Strength of Coarse Aggregates

Strength of coarse aggregates is difficult to measure. While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete ...

Influence of Crushed Coarse Aggregates on Properties

From experiment it was observed that, A-1 coarse aggregates exhibited more compressive strength (for both 1 weeks and 4 weeks) than A-2 coarse aggregates. Compressive strength was increased moderately for both type crushed aggregates with the decrease of w/c ratio. For A-1 coarse aggregate, lower compressive strength (14 MPa) was recorded for Group-I and higher compressive strength
