8. Green means 'Environment', concrete is obtained from the waste industrial products. Thus it is called as 'GREEN CONCRETE'. Global warming is one of the major threats to the environment. The major principle of global warming is CO2 emission. Concrete is one of the major way for CO2 emission. Concrete emits 10% of total CO2 …
In terms of the use of industrial waste materials, as a substitute material by reducing the percentage amount of the weight of the cement with the composition ratio varies based on the comparative ...
5. CONCRETE Concrete is a composite material composed of gravels or crushed stones (coarse aggregate), sand (fine aggregate) and hydrated cement (binder),and imparts considerable hardness to the mixture. The cement reacts chemically with the water and other ingredients to form a hard matrix which binds all the materials …
Numerous scientific studies have been conducted, and a wide range of new inorganic geopolymer composite applications have emerged as a result. This innovative material can be made from agricultural waste sources rich in aluminosilicate, which provides best substitute for traditional cement in terms of both quality and cost. This …
Green Concrete Seminar and PPT with pdf report: Green Concrete is that type of concrete that is used to create the construction materials having a lesser effect on the environment. This version of concrete is made up of a mix of industrial waste and inorganic polymer. The most commonly used way to produce green concrete is by …
For example: Using coarse aggregate obtained from concrete waste, for preparation of fresh concrete. • Recycling: The process of converting waste materials into new ones for reduction of …
They found that self-compacting concrete with a high volume of fly ash has less environmental impact with less raw material and construction cost, making it a promising …
The concrete waste was collected from the waste yard in the college campus, segregated, crushed in jaw crusher, sieved, washed and used for concreting for a mix proportion of …
Construction debris and demolition waste constitute 23% to 33% of municipal solid waste, and demolished concrete contributes the largest share of this waste material. Use of …
This document discusses construction waste recycling. It notes that construction generates a significant amount of waste and that recycling can reduce environmental impacts. It identifies several materials commonly recovered from construction sites, such as asphalt, wood, gypsum wallboard, metals, concrete, brick, …
This paper presents an overview of the published literature on the use of E-waste in concrete. Effect of E-waste on the properties of concrete such as compressive strength, …
3. Introduction: Demolition sites & restoration schemes are large amounts of solid waste. Recycling of concrete & other building materials is difficult & uneconomical. It is possible to reuse most of the building materials & components. As the volume of demolition waste is huge allowing the waste to be crushed, processed, & reused as …
Green concrete is a concept of integrating environmental considerations in concrete design and construction. It considers source depletion of raw materials, concrete mix design, structural design, construction, and maintenance of concrete structures (Prusty et al., 2016).Green concrete encourages sustainable and innovative use of waste …

Industrial waste materials in concrete and their influence on physical & mechanical properties & durability of concrete This document discusses the use of pozzolanic materials, including natural …
6. Essential Parameters for Repair Materials Low Shrinkage: It is well known that the cementitious repair materials shrink with passage of time. Most of the shrinkage generally takes place in the initial period from the time of casting to 21 days. Therefore, cementitious repair material in its original form, if used for repair to concrete/ …
The document discusses methods for waste disposal and management, focusing on reducing, reusing, and recycling (the 3 Rs). It defines recycling as processing used materials into new products, which prevents waste and reduces environmental impacts. It provides examples of materials that can be recycled like glass, paper, …
Numerous waste materials are generated from manufacturing processes, service industries and municipal solid waste. This has contributed greatly to the production of plastic related waste research is being carried out on the utilizations of waste products in concrete. Such waste products include tires, plastic, glass, steel, E-waste.
C&D waste is nothing but a waste materials consist of the debris generated during the construction, renovation, and demolition of buildings, roads, and bridges. C&D materials often contain materials that inter alia include concrete, asphalt, wood, metals, gypsum, plastics and salvaged building components.
