the aforementioned drawbacks of the recycled aggregate concrete by incorporation of mineral admixtures. It was found that the use of mineral admixtures in concrete produced with treated RCA enhances both the mechanical and durability properties. Thus, the concrete produced with treated RCA and mineral admixture will lead to sustainable development.

Dec 16, 2016· 6F5 is a recycled aggregate that is made up of crushed hardcore materials including crushed concrete. In general, our crushed concrete contains materials that range in size from 75mm down to dust making it perfectly suited for use as bulk fill. A recycled aggregate such as 6F5 is formed by the processing of inorganic material that has previously been used in construction.

Sep 03, 2017· For example, the density of concrete is determined by the density of the aggregate. Soft, porous aggregates can result in weak concrete with low wear resistance, while using hard aggregates can make strong concrete with a high resistance to abrasion. Aggregates are of two basic types: Coarse: crushed rock, gravel or screenings.
