dry weight of 20 mm aggregate

Aggregate: Mechanical Properties of Aggregate | Concrete ...

For aggregates upto 40 mm size the machine is rotated for 500 revolutions and for bigger size aggregate 1000 revolutions. The charge is taken out from the machine and sieved on 1.7 mm sieve. Let the weight of oven dry sample put in the drum = W Kg. Weight of aggregate passing through 1.7 sieve = W 1 Kg. Then abrasion value = [(W 1 /W) x 100]

Strength of RCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubed) compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.
