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.
Reusing of glass powder and industrial waste materials in concrete
Abstract A huge amount of concrete is consumed in the construction work. A good quality concrete is mixing of cement, fine and coarse aggregates, water and admixtures as needed to obtain an optimum quality and economy. In this study investigation were carried out on compressive strength, split tensile strength and water absorption of M-40 grade of concrete mixes with 20% constant replacement of waste glass powder in cement and partial replacement of waste foundry sand in fine aggregate. From the test results, strength are achieved very less on 7th and 14th das but it increases on the 28thday. High strength values found at 40% replacement level in strength parameters. Keywords: waste glass powder, waste foundry sand, eco-friendly, concrete mix.
Bottom ash as a partial replacement of fine aggregate
This document presents research on using bottom ash, a byproduct of coal burning, to replace fine aggregates in concrete. A group of students conducted experiments with 0%, 20%, 40%, and 60% replacement of fine sand with bottom ash. Test results showed compressive strengths of 49.7, 47.8, 43.6, and 41.2 MPa at 28 days, respectively, indicating strength decreases as replacement increases. While bottom ash concrete is weaker, it can replace lower grade concretes. Using bottom ash in this way utilizes a waste product, reduces environmental contamination from ash disposal, and decreases demand for natural sand.

Portland cement concrete is an artificial rock composed of aggregates, water, and a cementing agent like Portland cement. Portland cement is produced by burning and grinding a mixture of limestone, silica, alumina, and iron. The major constituents of Portland cement are compounds like C3S, C2S, C3A, and C4AF that form during burning and fusion and influence properties like strength. Concrete is composed of cement, water, fine aggregate, coarse aggregate, and sometimes admixtures. Admixtures are added during mixing to improve properties and aid construction.

Portland cement concrete is an artificial rock composed of aggregates, water, and a cementing agent like Portland cement. Portland cement is produced by burning and grinding a mixture of limestone, silica, alumina, and iron. The major constituents of Portland cement are compounds like C3S, C2S, C3A, and C4AF that form during burning and fusion and influence properties like strength. Concrete is composed of cement, water, fine aggregate, coarse aggregate, and sometimes admixtures. Admixtures are added during mixing to improve properties and aid construction. Curing protects concrete from moisture loss and temperature extremes to ensure proper strength development.

Concrete Technology Study Notes
Cement is a binding agent that undergoes hydration when mixed with water. There are various types of cement including ordinary Portland cement (OPC), rapid hardening cement, and sulphate resisting cement. Cement provides early strength through C3S and later strength through C2S. Heat is generated during cement hydration through an exothermic reaction. Proper storing, grading of aggregates, minimizing segregation, and adding admixtures can improve the properties of concrete.
Cement/Concrete technology
Cement is a binding agent that undergoes hydration when mixed with water. There are various types of cement including ordinary Portland cement (OPC), rapid hardening cement, and sulphate resisting cement. Cement provides early strength through its C3S content and later strength through C2S. Proper storing, labeling and stacking of cement bags is important to maintain quality. The hydration of cement is an exothermic reaction that produces heat and results in the formation of compounds like C-S-H gel and Ca(OH)2. The heat of hydration can cause cracking in large concrete structures like dams. Admixtures are used to modify properties of fresh and hardened concrete.

Role of water in man made rock.pptx
Water plays a crucial role in concrete as it is required for the chemical process of hydration where water reacts with cement to gain strength over time. The water-cement ratio affects properties like strength and durability, with lower ratios producing higher strengths and more durable concrete. Proper curing with water is also important to ensure continued hydration and development of strength and durability.

This document summarizes an experimental investigation into the strength properties of pervious concrete compared to conventional concrete. Pervious concrete has a higher permeability due to its interconnected pore structure and lower cement content. Testing found that pervious concrete has a lower unit weight and compressive strength but higher void ratio than conventional concrete. The compressive strength of pervious concrete was 7 MPa, 15 MPa and 22 MPa at 3, 7 and 28 days respectively, compared to 28.22 MPa, 39.78 MPa and 46.5 MPa for conventional concrete. While pervious concrete is weaker, it provides environmental benefits such as reduced stormwater runoff and groundwater recharge.

The document presents the results of an experimental study on partially replacing cement with marble dust powder in concrete. Marble dust powder is a waste material produced during the quarrying and processing of marble. The study tested different replacement levels of cement with marble dust powder in M30 grade concrete. It was found that replacing up to 10% of cement with marble dust powder increased the compressive strength of concrete compared to conventional concrete. Replacing up to 15% of cement increased the split tensile and flexural strengths. Higher replacement levels led to reduced strengths. Therefore, the study concluded that marble dust powder can be effectively used as a partial replacement for cement in concrete production at optimal replacement levels.
