1. Water Absorption Test of Aggregate: Formula. The formula that we need to utilize to calculate aggregate water absorption is as follows:. Weight of saturated aggregates in the air (A) = Weight of oven-dry aggregates in the air (B) = Water Absorption = (A-B)/B x If the Water Absorption value is less than 2%, aggregate can be used in construction.
The document describes the DLBD (Dry Loose Bulk Densities) method for calculating material requirements for a nominal M-20 concrete mix with a ratio of 1:1.5:3 for cement:sand:aggregate. It determines that a 50 kg bag of cement contains 0.035 cubic meters and requires 0.0525 cubic meters of sand and 0.105 cubic meters of aggregate. It then converts these volumes to …

The abrasive charge is also chosen in accordance with table and placed in the cylinder of the machine, and …
Sampling for Crushing Test of Aggregate. For the Aggregate crushing value test, an aggregate sample passing through a 12.5 mm IS sieve and retained on a 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mold about 6.5 kg of a sample of aggregate is sufficient.
