Nov 16, 2017· Hello! My group mates and I are working on a project concerning potential reinforced concrete hollow blocks using junk shop materials. We're pretty new to the entire process, and we're not sure of how we will arrive to our results (if the final results will be declared via machine or derived through a certain formula).

The compressive strength of concrete test is one of the post-test widely doing at the site to find out the compression strength of particular concrete batch. The compressive strength of concrete is defined as the maximum crushing stress can withstand by the concrete.

Compressive strength of a brick is determined by testing the brick under standard conditions using a Compression testing machine. The procedure as mentioned in IS 3495 (Part-2) shall be used to determine the compressive strength of brick work.

Example: You've been asked to calculate the compressive strength of a concrete cylinder. The cross-sectional faces of the cylinder each measure 6 inches across, …

Note down the crushing load for each cube separately and then multiply the load with 2204 so that it is converted to pounds. Then divide each crushing load value by the area of cross section of cube which in this case is 4 in 2. This will give the compressive strength of each cube which may vary in value.
