This document presents the results of a study on the performance of concrete containing zeolite as a supplementary cementitious material (SCM). Seventeen concrete mixtures were prepared with 0-40% replacement of Portland cement with untreated and calcined zeolite. The fresh and hardened concrete properties were tested. The main findings were that zeolite reduced workability but a water reducer was able to maintain workability. Untreated zeolite concrete had higher density while calcined zeolite concrete was lighter. Compressive strength improved at 10% replacement but declined at 25-40% replacement compared to the control concrete. Thus, zeolite can be used as a SCM to improve strength and enable production of lighter weight concrete.
DURABILITY STUDIES OF GGBS AND METAKAOLIN BASED GEOPOLYMER CONCRETE Ijciet 08...IAEME Publication
The objective of this research work was to produce a carbon dioxide emission free cementious
material. The geopolymer concrete is such a vital and promising one. In this study, geopolymer is
prepared from ‘Ground Granulated Blast Furnace Slag’ (GGBS) a powder from grinding the byproduct
of slag waste from blast furnace of steel plants and metakaolin from industry. The Alkaline
liquids used in this study for the polymerization process are the solutions of sodium hydroxide
(NaoH) and sodium silicate (Na2Sio3).A 8 Molarity and 10 Molarity solutions was taken to prepare
the mix. The cube compressive strength was calculated for different mixes. The cube specimens are
taken of size 150 mm x 150 mm x 150 mm. Ambient curing of concrete at room temperature was
adopted. In total 180 cubes were casted for their compressive strength at age of 28 days
respectively. The test data indicate that on exposure to 5% Sodium Sulphate, Sulphuric Acid and
Sodium Chloride, the losses in weight, and strength of geopolymer concrete (GPC) are
significantly much less than those for cement concrete. Thus the geopolymer concrete is considered
to be an environmentally pollution free construction material.

Concrete is the most widely used man-made construction material in the world and is consumed second only to water on this planet. It is obtained by mixing the cementitious materials, water and aggregates in the required proportions. However, the various required performance attributes of concrete including strength, workability, dimensional stability and durability, often impose contradictory requirements on the mix parameters to be adopted, there by rendering the concrete mix design a very difficult task.
The increase in global warming has resulted a wide range of change in earth’s temperature, the source being emission of carbon dioxide gas from the production process of cement. Use of naturally available pozzolanic waste materials (fly ash & granite powder) as a partial substitute of OPC cement in mortar mix has seen a wide potential in the utilization of these waste material and also enhancing the properties of mortar mix and thus reducing the environment impact caused by manufacturing of cement. In this study the effect of using fly ash & granite powder is used as a partial substitute of ordinary port-land cement and to reduce the cost of the cement.
An investigation was conducted to determine the suitability of using fly ash (bi-product from thermal power plant) and waste granite powder as partial replacement for cement for concrete production. Apart from the control concrete sample which had 100% cement all the other samples were treated to 20%, 40%, 60%, 80% and 100% replacement of cement with flyash and granite powder. Concrete cubes of 150mmx150mmx150mm, cylinders of 150mm diameter and 300mm height, beams of 100mmx100mmx500mm were made with the various proportions of cement, sand and coarse aggregates in a mix ratio of 1:2.2:3, water -cement ratio of 0.50 and cured over 28 days. The results of compressive strength tests show that the strength of the concrete cubes with varying amounts of cement and fly ash and granite powder changed marginally. This was interpreted to mean that the partial replacement of cement with fly ash and granite powder up to 20% in concrete results in about 1.4% increase in the strength of the concrete. The compressive strength of concrete cubes is 33N/mm2, flexural strength of concrete beams is 5.10 N/mm2 and split tensile strength of concrete cylinder is 2.34 N/mm2 for 20% replacement.

Experimental Study on Use of Waste Marble Dust in ConcreteIJERA Editor
Concrete is the most important component used in the construction industry throughout the world, where the
fine aggregate is generally natural sand. The use of sand in construction activities results in the excessive
mining. Due to excessive mining, natural resources are getting exhausted, results in increase in scour depth and
sometimes flood possibility. Thus, it is becoming inevitable to use alternative material in concrete.Marble is one
of the important materials used in the construction industry. Marble powder is produced from processing plants
during the sawing and polishing of marble blocks and about 20 - 25% of the processed marble is turn into
powder form. Disposal of the marble powder material from the marble industry is one of the environmental
problems worldwide today.The present study is aimed at utilizing Waste marble powder construction industry
itself as fine aggregate in concrete, replacing natural sand. The replacement is done partially and fully in the
proportion 0%, 25%, 50% and 100% and its effect on properties of concrete were investigated.

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.
Study on the Effect of Ggbs & M Sand in Self Compacting oncretetheijes
Conventional concrete is the most widely used construction material throughout the world because of its versality, mouldability, durability, and resistance to fire and energy efficiency. However, its major disadvantages like poor tensile strength, limited ductility and little resistance to cracking resists its use as a structural material. Hence, in order to overcome these difficulties several new materials have been developed in the recent past.Admixtures are ingredients other than water, aggregates, hydraulic cement and fibers that are added to the concrete batch immediately before or during mixing. Mineral admixtures are usually added to concrete in larger amounts to enhance the workability of fresh concrete, to improve resistance of concrete to thermal cracking, alkali-aggregate expansion and sulphate attack and to enable a reduction in cement content. The objective of this study is to evaluate the effectiveness of various mineral admixtures in producing SCC. In this study the scope of GGBS ( Ground granular blast furnace slag ) as a mineral admixture to some percentage replace cement in SCC were studied. The study showed that a maximum of 50% GGBS were able to be used as a mineral admixture without affecting the self-compactability

Self compacting concrete for slip form pavingeSAT Journals
Abstract Slip form paving has been extensively used worldwide for construction of pavements. During the process of paving, concrete mix with a slump less than 50 mm is placed in front of a paver. Because of the low consistency of the mix, a great deal of vibration is needed to move entrapped air and compact the concrete. There is a need to overcome problem by designing a concrete that would not require vibration to compact the concrete mix, at the same time stability after extrusion and high flexural strength. Mix design based on the absolute volume concept was adopted to fabricate SFSCC. Volume of paste of 0.38 and water content of 200 kg/m3 was kept constant throughout the study. Cement content was varied from 360 to 425 kg/m3, 3 mixes of SCC with GGBS (SFSCC-S), 3 mixes of SCC with 2% of alccofine replaced by cement (SFSCC-SA) and 3 mixes of SCC with 2% of metakaolin replaced by cement (SFSCC-SM) is reported. The quantity of polypropylene fibers used in all the mixes was 900 gm/m3. Slump, spread, green strength and compaction factor were evaluated for all the 9 mixes. To simulate the practical construction process, a mini paver system was fabricated. The strength parameters compressive and flexural strength of concrete was evaluated at 7 days and 28 days. Keywords: Slip form paving, alccofine, SCC, GGBS, metakaolin, SFSCC, SP.
Disposal of tyre rubber is becoming a huge problem in India day by day.
Researchers are trying to use those rubber in civil engineering projects from long day

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers.
