This document is a project report on developing water absorbing pavement using porous concrete. It discusses mixing porous concrete using various materials like cement, coarse aggregates, and admixtures. Five concrete samples with different fine aggregate proportions were made and tested for properties like compressive strength and infiltration rate. Replacing a part of cement with materials like fly ash increased the concrete's strength while also making it more environmentally friendly. The report concludes that porous concrete allows water to pass through it, and finds effective proportions use coarse aggregates larger than 10mm but smaller than 20mm.

Partial Replacement of Cement by Saw Dust Ash in Concrete A Sustainable ApproachIJERD Editor
Concrete industry is one of the largest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the biggest challenge concrete industry is facing. In this paper, the issues of environmental and economic concern are addressed by the use of saw dust ash as partial replacement of cement in concrete. Cement was replaced by Saw Dust Ash as 5%, 10%, 15% and 20% by weight for M-25 mix. The concrete specimens were tested for compressive strength, durability (water absorption) and density at 28 days of age and the results obtained were compared with those of normal concrete. The results concluded the permissibility of using Saw Dust Ash as partial replacement of cement up to 10% by weight for particle size of range 90micron.

The Use Of Permeable Concrete For Ground Water RechargeIJERA Editor
In order to develop Smart Cities in India, we need to develop smart technologies and smart construction materials. Permeable concrete an innovative material is environment friendly and a smart material which can be used for construction of several structures. In India, the ground water table is decreasing at a faster rate due to reduction in ground water recharge. These days, the vegetation cover is replaced by infrastructure hence the water gets very less opportunity to infiltrate itself into the soil. If the permeable concrete which has a high porosity is used for the construction of pavements, walking tracks, parking lots, well lining, etc. then it can reduce the runoff from the site and help in the ground water recharge. Such type of smart materials will play an important role for Indian conditions where government is putting lot of efforts to implement ground water recharging techniques. During the research work, the runoff for a particular storm was calculated for a bitumen pavement on a sloping ground. Later after studying the various topographical features, the traffic intensity and the rainfall for that particular area, the concrete was designed and tested for the different proportion and thus the mix design for the permeable concrete was finalized based upon its permeability and strength characteristics. Later by using this permeable concrete the infiltration and runoff for the same storm was compared and studied. The research paper will thus give an account of the properties of permeable concrete where it can be used over an existing road.

The results of an experimental investigation to study the effects of partial replacement of cement with fly ash in rubberized and coconut shell concrete. The percentage of rubber used in this study was 5% replaced with coarse aggregate and fly ash varies from 0-20% were replaced with cement in conventional concrete. One size of tire rubber chips are used of about 10mm.
Rubber is produced excessively worldwide every year. It cannot be discharge off easily in the environment as its decomposition takes much time and also produces environmental pollution. In such a case the reuse of rubber would be a better choice.
In order to reuse rubber wastes, it was added to concrete as coarse aggregate and its different properties like compressive strength, Tensile strength, ductility etc. were investigated and compared with ordinary concrete.
As a result it was found that rubberized concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. The compressive strength of rubberized concrete can be increased by adding some amount of silica to it.
Properties of concrete with coconut shells (CS) as aggregate replacement were studied. Control concrete with normal aggregate and CS concrete with 10-20% coarse aggregate replacement with CS were made. Two mixes with CS and fly ash were also made to investigate fly ash effect on CS replaced concretes. Constant water to cementitious ratio of 0.6 was maintained for all the concretes. Properties like compressive strength, split tensile strength, water absorption and moisture migration were investigated in the laboratory. The results showed that, density of the concretes decreases with increase in CS percent.
Workability decreased with increase in CS replacement. Compressive and split tensile strengths of CS concretes were lower than control concrete. Permeable voids, absorption and sorption were higher for CS replaced concretes than control concrete. Coarse aggregate replacement with equivalent weight of fly ash had no influence when compared with properties of corresponding CS replaced concrete
The mix design was targeted to be M15 grade of concrete. The mix proportion of concrete was 1:2:4 with water cement ratio of 0.45.The fresh and hardened properties of rubberized concrete produced at two different replacements ratios of fly ash compared to the conventional concrete without rubber and fly ash.
The test result indicate that there was a small reduction in the strength with the 5% replacement in rubber content as compared with the conventional concrete. However, the increase of fly ash from 10% to 20% improved the mechanical properties of rubberized and coconut shell concrete.
This study explores the effects of rubber particles and coconut shell on some properties of concrete.
Variation of Compressive strength and water absorption of concrete made by Tw...ijsrd.com
Nowadays construction materials are increasingly evaluated by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications. The concrete in this paper is produced by utilizing alternative and recycled waste materials such as fly ash and recycled concrete aggregates to reduce energy consumption, environmental impact, and usage of natural resources. The inferior quality of recycled aggregate (RA) has restricted its use to low-grade applications such as roadwork sub-base and pavements, while its adoption for higher-grade concrete is rare because of the lower compressive strength and higher variability in mechanical performance of RA. A new concrete mixing method, two-stage mixing approach (TSMA), was advocated to improve the quality of RA concrete (RAC) by splitting the mixing process into two parts. In the current paper we will discuss two parameters on which the concrete made by TSMA has been tested for strength characteristics viz. compressive strength and flexural strength. These parametric properties are compared with the conventional concrete with the variation of percentage of recycled coarse aggregates(RCA) and fly ash.
compressive strength of concrete containing milled glass as partial substitut...IJAEMSJORNAL
This work reports the outcome of an experiment carried out by using milled glass (MG) of varying percentages (20%, 40% and 60% by weight)of cement in concrete making. MG was sourced for and milled to required fineness. The concrete was batched with mix ratio of 1։2։ 4. Concrete Cube specimens produced were allowed to cure for 7-28 days and compressive strength, slump and setting time tests were carried out and were compared with those of conventional concrete (0% MG). Results obtained showed that compressive strength of the concrete increased with increase in length of curing age, but decreased as the percentage of MG increased. However, the strength still remained in the allowable range of workability for concrete in line with British standard. MG replacement of 20% was found to be the most suitable mix considering the strength and safe use of the concrete. It was concluded that MG replacement of 20% showed no significant loss in strength compared to the control sample and is stable and could be acceptable in most concrete. At the long run. Waste glass that currently constitutes waste concern in built environment in Nigeria can best be managed through alternative use in concrete production.
Pervious concrete is a concrete composite material consisting of coarse
aggregate, cement and water. Because of the absence of fine aggregate in the mixture,
the aggregates are bonded together at its points of contact by cement paste, resulting
in a high percentage of interconnected voids that, when functioning correctly, permit
the rapid percolation of water through the concrete. In this work, polypropylene
monofilament and fibrillated fibres are selected as raw materials in three varying
percentage. 0.2% of fiber is added by the total volume of concrete and a new method
for determining the permeability of pervious concrete that provides better design
methodology is used. The experimental test values of permeability are discussed and
validated using Avizo software. The mix design is done for the water to binder ratio of
0.30. Coarse aggregate of 10 mm and 4.75 mm are selected in order to reduce the
void content as per the ACI 522R-06 codal provision. The addition of polypropylene
fibers shows enhancement in mechanical properties of the pervious concrete as
expected
Comparision of Strength For Concrete With Rock Dust And Natural Sand Concrete...IJERA Editor
The Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust can be defined as
residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine
particles less than 4.75mm. Usually, Quarry Rock Dust is used in large scale in the highways as a surface
finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated
Elements. This project presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes
for Natural Sand in concrete. Design Mix for M30 and M40 has been calculated using IS 10262-2009 for both
conventional concrete and quarry dust concrete. Tests were conducted on cubes, cylinders and beams to study
the strength of concrete by using Quarry Rock Dust and the results were compared with the Natural Sand
Concrete. Cement motor ratios of 1:3 and 1:6 are prepared and observe the percentage of water absorption in
both Quarry Rock Dust and Natural sand for plastering.
Pervious concrete is one of the most promising sustainable materials now a days.
Pervious concrete is a zero slump, open graded material consisting of hydraulic
cement, coarse aggregates, admixtures and water. It is sometimes referred to as nofines
concrete. It is a special type of concrete having a high void content and is
becoming popular due to its potential to reduce the runoff to the drainage systems.
In this paper, the behavior of pervious concrete with different sizes of coarse
aggregate is studied. Various mix proportions were prepared by using different sizes
of coarse aggregates. The properties like permeability, porosity, density, strength and
durability of pervious concrete are studied.
The water cement ratio (0.31) and aggregate cement ratio are kept constant. The
study is conducted experimentally for 7, 28 & 56 days. The mix proportion of coarse
aggregate and its effect on properties of pervious concrete are studied and
corresponding graphs are hence obtained
An Experimental Paper on Compressive Strength of Pervious Concreteijtsrd
Pervious concrete has been in use in many countries over more than a century. Its higher porosity helps in percolating rain water directly to ground and thereby helps in recharging groundwater aquifer. In this study, pervious concrete of sizes of 6.3mm size aggregate were prepared with different water cement ratios to find the compressive strength. The purpose of this project is to analyze the feasibility of producing highly sustainable no fine concrete mixtures and evaluating the effect of W c ratio on the properties of pervious concrete. Porous concrete is produced by using ordinary Portland cement, coarse aggregates, and water. This concrete is tested for its property compressive strength. The results showed that the water cement ratio showed significant effect on compressive strength of Pervious concrete. S. Suryasri | Mr. K. S. B. Prasad "An Experimental Paper on Compressive Strength of Pervious Concrete" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-6 , October 2019, URL: https://www.ijtsrd.com/papers/ijtsrd28121.pdf Paper URL: https://www.ijtsrd.com/engineering/transport-engineering/28121/an-experimental-paper-on-compressive-strength-of-pervious-concrete/s-suryasri
Hence, it can be concluded concrete prepared with 3% NS and 6%
SF combination can be recommended for the structural applications. The increase in the strength
properties of concrete is due to the availability of additional binder in the presence of NS and SF.
The improved durability property of concrete is due to proper packing of NS and SF particles results
in reduction in voids and leading to dense concrete.

A Compatibility Study on Different Types of Cement and Plasticizerijsrd.com
It has long been a concrete technologist's dream to discover method of making concrete at the lowest possible water/cement ratio while maintaining a high workability. To a considerable extent this dream has been fulfilled with the advent of super plasticizers. It has added a new dimension to the application of admixtures with regards to production of high strength and flow able concretes. It is now possible to produce concrete with compressive strength of the order of 90Mpa (90 N/mm2). In the wake of energy conservation policy and diminishing supplies of high quality raw materials, there is a need to use marginal quality cements and aggregates for the production of concrete. In such instances the use of plasticizers/super plasticizers permits the production of concrete at low water/ cement ratios. We have taken ultra tech opc cement & coromandal ppc cement to find the compatibility by adding perma plast (plasticizer). The water cement ratio was maintained as 0.40 &0.45 for OPC & PPC respectively. To study the effect of these PP on various properties of concrete. The dosage of plasticizers/super plasticizers was measured as 1.5% for Perma plast for OPC & 1.3% for PPC by the weight of cement.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

4. Porous concrete is a performance-engineered concrete made with controlled
amounts of cement, coarse aggregates, water, and admixtures to create a mass of
aggregate particles covered with a thin coating of paste.
Pervious concrete has a rough and open texture that has been compared to a rice
cake.
Pervious concrete as a paving material have the ability to allow water to flow
through itself.
This property of porous pervious concrete reviews its applications and engineering
properties.
By replacing a part of cement with SOME CONSTITUENT, then it results the more
strength to the concrete. Hence it acts as an eco-friendly paving material.
In doing so, pervious concrete has the Ability to lower overall project costs on a
first-cost basis.
A pervious concrete mixture contains little or no sand, creating a substantial void
content.
Portland cement is partially replaced by supplementary cementitious materials,
such as fly ash, blast furnace slag , etc then the porous concrete could be
considered as environmentally concrete for sustainable construction.
5. 1. M. Aamer Rafique Bhutta a, K. Tsuruta b, J. Mirza was studied on
topic of Evaluation of high- performance porous concrete
properties.
AIM-The aim of this laboratory study was to evaluate the properties
of high performance porous concrete. Tests carried out on this
concrete were: slump, slump-flow, void ratio, and coefficient of
permeability, compressive and flexural strengths, and strength
development rate.
2. Y. Aoki*, R. Sri Ravindrarajah and H. Khabbaz
carried out study on Properties of pervious concrete
containing fly ash.
6. AIM- In this paper, the findings of an experimental investigation on
properties of pervious concrete are reported and discussed. The amount of
general purpose Portland cement has been reduced by introducing fly ash as
a cementitious agent in pervious concrete samples. The properties of various
pervious concrete samples including density, porosity, compressive
strength, water permeability and drying shrinkage have been carefully
measured.
7. To develop a strong and durable pervious cement concrete
mix using different types of fine aggregate with varying
quantity of fine aggregate and comparing properties of
different proportion of fine aggregate.
To make project eco-friendly by using ceramic waste.
8. In the past due to the scarcity of cement, the pervious
concrete has been used extensively.
The pervious concrete has lost its importance after
successful production of cement in large quantities.
But now-a-days, the usage pervious concrete has
gained its popularity due to many advantages.
By using the pervious concrete we can able to
recharge the ground water table and the storm water
disposal can also be done.
So, in future to tackle aforesaid problems and to
protect people from flood prone areas, the pervious
concrete is one effective solution.
9. MATERIAL USE:
CEMENT {53 GRADE OPC}
COARSE AGGREGATE {4.75mm-7.5mm}
WATER { W/C=0.4}
ADMIXTURE { Conplast SP430 ASTM-C-494 Type
'G, ETC}
CERAMIC WASTE {12mm-20mm}
10. A laboratory study evaluating strength and infiltration,
concrete mix was performed.
The experiments included compressive strength tests,
infiltration rate test on clean specimens.
5 different sample of M25 grade considered-
Sample 1: M25 concrete having proportion 1:1:2
Sample 2: M25 concrete having proportion 1:1:2 with no sand.
Sample 3: M25 concrete having proportion 1:1:2 with 5% sand.
Sample 4: M25 concrete having proportion 1:1:2 with 10% sand.
Sample 5: M25 concrete having proportion 1:1:2 with 15% sand.
9 cubes of each sample are prepared ,are cured
underwater and admixture is also added to increase
strength and durability.
On increasing sand strength of concrete increases but it
reduces the permeability.
Among 5 sample with desirable properties is choosen.
11. Ceramic waste can be used as an alternative for coarse
aggregate to make it more cost effective and ecofriendly .
The samples of concrete with different proportion of
coarse aggregate ,ceramic waste and cement are
considered –
Sample (composite ceramic and C.A. : Cement) –
2:1- 100% c.a.
2:1-75% ceramic waste and 25% c.a.
2:1-50%ceremic waste and 50% c.a.
2:1- 75%c.a. and 25%ceramic waste
2:1-100% ceramic waste
Sample with highest compressive strength is
considered.
16. Effective surface Runoff Management:
Permeable paving surface allows water to percolate though
itself. They are effective in managing runoff from paved surfaces,
thus providing local flood control.
Control over Pollutants:
Permeable paving surfaces keep the pollutants in place in the
soil or other material underlying the roadway, and allow water
seepage to groundwater recharge while preventing the stream
erosion problems.
Ground Water Recharge :
Permeable pavement contributes a lot in to ground water
recharge.
Reduction in Cost:
It reduces the need for traditional storm water infrastructure,
which may reduce the overall.
17. From the experimental results of investigation,
Porous concrete allows water passes through it. It
is not composed of fine aggregates. Aggregate
having size more than 20mm cannot be used,
because of larger voids cause settle down of
cement slurry. And aggregates having size less
than 10mm can give better results. Effective
utilization of waste product (fly ash ),and making
it as a eco-friendly concrete. Lesser percentage
of fly ash gives high strength than higher
percentage. Higher percentage of fly ash weaker
in cement bonding. Conplast Sp430 is good
admixture, and it increases the strength and
bonding between cement and aggregates.
