Evaluation of Aggregate Crushing Tests and Their

Six aggregates sampled from different sources were subjected to various aggregate tests, including the Los Angeles abrasion, micro-Deval, soundness magnesium, and acid insoluble tests. A Superpave mix with a 12.5-mm (1/2-in.) nominal maximum aggregate size gradation was produced with each aggregate source using the same PG The Los Angeles machine was used mainly for the mechanical treatment, as it was significant for indicating the relative quality or the competence of the aggregate. Meanwhile, its processing system performs a degradation from a combined action of abrasion or attrition, impact, and grinding in a rotating steel drum containing 12 spheres, Durability of Recycled Concrete Aggregates Prepared with

Resistance to fragmentation of recycled concrete aggregates

Recommendation for coarse recycled aggregate resistance to fragmentation categories for the use in concrete in the European standard [ 16] is based on the Los Angeles coefficient (LA) as specified in [ 17] for natural coarse aggregate. The Los Angeles (LA) test is an empirical measure of degradation of mineral aggregates of Resistance to Abrasion of Coarse Aggregate by Use of the Los Angeles. Machine.
