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 …

Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse Aggregate was collected from five different …

Sampling of Aggregates. Select coarse aggregate that passes through a 12.5mm IS sieve and is retained on a 10mm IS sieve. Heat the aggregate at 100 to 110°C for 4 hours, cool it to room temperature, and ensure that the material depth in the cylinder, after tamping as described below, is 10 cm. Determine the appropriate quantity by filling …
