How to Calculate Cement, Sand and Coarse Aggregate

For Beam, If we need to calculate the concrete volume, Volume = Length X Breadth X Width = 5 X 0.6 X 0.3 = 3.75 m3 For Column, If we need to calculate a concrete volume for the below Columns, Rectangular Column, Volume = Height X Breadth X Width = 5 X 0.6 X 0.3 = 0.9 m 3

Aggregate Moisture in Concrete - Concrete Construction

May 31, 2013 · I design my mixture with aggregates in the saturated surface-dry (SSD) condition. {Answer} The moisture condition of aggregates in concrete is very important. We are all familiar with Abrams Law, which states that, all other things being equal, compressive strength of concrete is dependent on the ratio of mass of water to cementitious material.

ASTM C1585 - 20 Standard Test Method for Measurement of Rate

1.1 This test method is used to determine the rate of absorption (sorptivity) of water by hydraulic cement concrete by measuring the increase in the mass of a specimen resulting from absorption of water as a function of time when only one surface of the specimen is exposed to water. The specimen is conditioned in an environment at a standard ...
