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.
