[PDF] COMPARISON OF STRENGTH PERFORMANCE

This study focuses on the relative performance of uncrushed aggregates and crushed aggregates for concrete in strength gaining. The study was conducted for medium grade concrete (concrete having cube compressive strength at 28 days between 6 Mpa to 50 Mpa). There is a general belief that crushed aggregates contribute higher strength in concreting compared to uncrushed aggregates.

What is Crushed Aggregate? (with pictures)

Crushed aggregate is produced in quarries by processing larger rocks into smaller pieces. Crushed aggregate, also known as rock aggregate, refers to a crushed stone product produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger stones are processed in an impact crusher to create crushed rock aggregate.

The reported research indicates that aggregates made with uncrushed or partially crushed gravel particles have a lower resilient modulus than do those with angular crushed particles. This effect has been attributed to the higher num- ber of contact points in crushed aggregates, which distrib- ute loads better and create more friction between ...
