Calculate the cumulative percentage of retained aggregate on each sieve.
Calculate Sand & Gravel per 50kg Cement Bag in
The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.
Bulk Density Of Aggregates Engineering Discoveries
If a statement is like A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. After that, weight the aggregate mass that is inside the container and divide it by the volume of the container. This will give you the bulk density of the loose aggregates.
