Cement and cement concrete | PPT

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 together into a durable stone-like …

Aggregates of Concrete | PPT

Aggregates make up 65-80% of concrete's volume and are inert fillers that float in the cement paste. Their characteristics impact the performance of fresh and hardened concrete. Aggregates are classified based on size, specific gravity, availability, shape, and texture. Proper aggregate grading leads to a dense, strong concrete mixture.

3. The large quantities of concrete should not be deposited at a time. Otherwise the concrete will start to flow along the formwork and consequently the resulting concrete will not have uniform composition. 4. The concrete should be dropped vertically from a reasonable height. For vertical laying of concrete, care should be taken to use stiff mix.
