Porous asphalt pavement
“When it pours, it’s porous.”
Porous asphalt pavements offer developers and planners a new tool in their toolbox for managing storm water. These pavements, used mostly for parking lots, allow water to drain through the pavement surface into a stone recharge bed and infiltrate into the soils below the pavement. Such pavements have been proving their worth since the mid-1970s, and recent changes in storm water regulations have prompted many consulting engineers and public works officials to seek information about them
Creep and shrinkage
This document discusses creep and shrinkage in concrete structures. It defines creep as time-dependent deformations of concrete under load, and shrinkage as shortening of concrete due to drying that is independent of applied loads. Factors that affect creep include concrete mix proportions, aggregate properties, age at loading, curing conditions, cement properties, temperature, and stress level. Factors that affect shrinkage include drying conditions, time, and water-cement ratio. The document also discusses types of shrinkage such as plastic, drying, autogenous, and carbonation shrinkages. It outlines effects of creep and shrinkage on structures and methods to prevent shrinkage.
Two Layer Porous Asphalt - Danish Experiences - BRRC Seminar 2005
This document summarizes a study on two-layer porous asphalt pavements in Copenhagen. The study aimed to develop noise-reducing pavements, test them under Danish conditions, and analyze their acoustic and structural properties over time. Initial results found the thickest porous pavement reduced noise by 5-6 dB compared to 1-2 dB for conventional pavements. However, pavements with smaller aggregates clogged more over time. Compared to barriers and insulation, porous asphalt provided better noise reduction per cost. Analyses of core samples helped evaluate clogging. Researchers proposed renewing top layers to continue the study.

SHOTCRETE TECHNOLOGY
Shotcrete or sprayed concrete (Gunite®) is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. It is typically reinforced by conventional steel rods, steel mesh, or fibers.
Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions. In pool construction, however, shotcrete refers to wet mix and gunite to dry mix. In this context, these terms are not interchangeable.
Shotcrete is placed and compacted at the same time, due to the force with the nozzle. It can be sprayed onto any type or shape of surface, including vertical or overhead areas.

Abstract: This project is regarding the investigation on compressive strength, flexural strength and tensile strength of unconventional concrete using waste material. The material used in this project is palm oil clinker and it has been used to replace conventional coarse aggregate in concrete. The main objective of this research is to support the usage of waste product which helps to reduce the usage of conventional construction materials that are decreasing in terms or quantity and increasing in terms of price. The rate at which extinction of natural resources and pollution is increasing day by day is becoming alarming. The pollution of the environment in causing irreparable damage to the earth and it can be avoided by the usage waste materials which can be easily obtained. Other than that, factors affecting the mechanical properties of concrete are studied throughout the literature review. This has been done in order to combine information gained into this research and provide a better solution for palm oil clinker concrete. The various tests were performed on five different types of concrete mix with different percentage of palm oil clinker as a coarse aggregate replacement. This is to study the characteristic of palm oil clinker in concrete and as well as the changes that it makes in the strength of concrete. From the result obtained, due to its water absorbing characteristic, size and shape, palm oil clinker increase the bonding between aggregate by filling in the voids. Furthermore palm oil clinker enables internal curing which allows concrete strength to be higher. It has reduced the porosity of concrete, which means it has increased the strength of concrete. Lastly, palm oil clinker as coarse aggregate replacement in concrete has a major impact in the future of construction industry by drastically increasing the strength of concrete as well as the eradication of waste.

A construction industry plays vital role in India which leads into the economic developments. The materials like fine
aggregate, coarse aggregate are used to prepare cement concrete which are easily available natural resources in our
country, but now there is high demand in materials which have gone to a high scenario.
The quantity of fly ash produced from thermal power plants in India is approximately 80 million tons each year, and its
percentage utilization is less than 10%. Majority of fly ash produced is of Class F type. During the last few years, some
cement companies have started using fly ash in manufacturing cement, known as ‘Pozzalanic Portland cement. It mainly
concentrated on replacement of cement with fly ash but production of artificial aggregate with fly ash helps in utilizing
large volume of fly ash in concrete. The world is much interested in this part recently due to this large scale utilization
which also reduces environmental pollution and dwindling of natural resources.

The study found that as the percentage of plastic optical fibers in the transparent concrete increased from 2.5% to 4%, the slump, weight, compressive strength, and split tensile strength of the hardened concrete also increased compared to conventional concrete without fibers. At 28 days, the compressive strength was up to 10% higher for transparent concrete with 4% fibers compared to conventional concrete. Thus, the addition of plastic optical fibers improved the strength properties of the transparent concrete.Utilization of solid waste in manufacturing of brick
This document discusses utilizing solid waste in the manufacturing of bricks. Solid waste such as plastic is a growing problem and non-biodegradable. The authors propose using solid waste as a substitute for some materials traditionally used to make bricks, such as clay. They conducted experiments making bricks with proportions of solid waste like rubber and plastic. The bricks were then tested for properties like compressive strength. The solid waste bricks performed comparably or better than conventional bricks in testing. Additionally, using solid waste materials reduces costs and environmental impacts compared to traditional brick production. The authors conclude solid waste bricks could provide an economical and sustainable building material that also helps address the problem of non-degradable solid waste.
IRJET-Replacing the Fly Ash by STP Dry Sludge in Manufacturing of Fly Ash Bricks
This document describes a study that experimentally tested replacing fly ash with sewage treatment plant (STP) dry sludge in manufacturing fly ash bricks. STP sludge is a waste product that needs disposal, while fly ash is commonly used in brick production. The study replaced fly ash with 5%, 7.5%, 10%, and 12% STP dry sludge by weight. Tests on the dry sludge fly ash bricks showed that replacing up to 7.5% of the total weight with sludge yielded satisfactory results, with compressive strength and water absorption similar to standard fly ash bricks. Higher sludge content above 7.5% reduced brick strength. The study thus demonstrates the feasibility of using STP sludge as a
IRJET- Utilization of Ceramic Waste in Grout
This document summarizes research on utilizing ceramic waste in grout. Ceramic wastes like marble dust, granite dust, and crushed sand were used to create grout mixtures. Different sieve sizes and water ratios were tested to determine optimal flowability and strength. Compressive strength and tensile strength tests were performed on grout cubes and cylinders. The optimal mix was found to be 45% marble dust, 45% granite dust, 10% crushed sand, and 0.45% water ratio, achieving an average compressive strength of 11.37 N/mm2 and tensile strength of 3.65 N/mm2. This grout mixture provides equivalent strength to commercial grouts but at a significantly reduced cost of around 70

This document summarizes a study on using cement stabilization to improve the strength of conventional waste and marginal materials for pavement construction. Four samples - mine waste, river material, and hard shoulder material - were collected and tested with 3%, 6%, and 9% cement content. Testing included CBR, unconfined compressive strength, and durability. The results showed that with cement stabilization, the materials improved in strength and durability over time and met standards for base and sub-base layers in some cases. Using these stabilized waste and marginal materials could help reduce the cost of road construction while providing adequate engineering properties.
STUDIES ON STABILIZED MUD BLOCK AS A CONSTRUCTION MATERIAL
Soil as a building material is available in most areas of the world. In developing countries, earth
construction is economically the most efficient means for house construction with the least demand of resources.
Investigation is carried out to find the suitable proportion of locally available materials such as soil , coir , straw etc. with
cement as stabilizers for improving the strength of locally available mud blocks and thus to provide affordable housing.
Using soil (from areas of Neriamangalam) and stabilizers (cement, lime, straw fibre, coir fibre, plastic fibre), eleven
different types of samples were prepared. Tests were conducted on these samples in order to evaluate their performance
such as compressive strength and total water absorption on which the durability of the blocks depend. The investigation
has revealed that, out of all block samples, blocks which are produced from10% cement (C10), 10% cement with 3% coir
fibre (C10C) and 10% cement with 3% plastic fibre (C10P) have compressive strength and total water absorption values
above the recommended minimum values for structural work.(IS 1725:1992)

CASTING AND EVALUATING THE INTERLOCKING BRICKS USING ORGANIC WASTE MATERIAL.
The document discusses casting and evaluating interlocking bricks using organic waste material like textile sludge. Bricks containing 15% textile sludge showed the best results with a compressive strength of 3.98 N/mm2 and water absorption of 15%, compared to conventional bricks. The study concludes that using a 15% mixture of textile sludge and clay in interlocking bricks produces strong, environmentally-friendly construction materials while utilizing industrial waste.
REPLACEMENT OF FINE AGGREGATE WITH GLASS POWDER IN HIGH PERFORMANCE CONCRETE
This project report examines replacing fine aggregate with glass powder in high performance concrete. Eight students conducted tests to study the effects of partial replacement of fine aggregate with glass powder at levels of 10%, 20%, and 30%. Tests were performed to determine properties of materials used including cement, fine aggregate, glass powder, and coarse aggregate. Concrete mixtures were designed and casted, and cubes were tested for compression strength at ages of 3, 7, and 28 days. The results were compared to a control concrete without glass powder. The objective was to evaluate the use of glass powder as a partial replacement of fine aggregate and its impact on concrete performance.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
