The Compressive Strength of Concrete determines the quality of Concrete. This is generally determined by a standard crushing test on a concrete cylinder. This requires engineers to build small concrete cylinders with different combinations of raw materials and test these cylinders for strength variations with a change in each raw material.

2. Crushing Strength or Compressive Strength Test on Bricks. Crushing strength of bricks is determined by placing brick in compression testing machine. After placing the brick in compression testing machine, apply load on it until brick breaks. Note down the value of failure load and find out the crushing strength value of brick.get price

The specimen so placed in the compression testing machine is loaded in the rate of 14 N/mm 2 per minute. The crushing load is noted. Then crushing strength is equal to this crushing load divided by the area where the load is applied. At least three specimens must be tested, and the average ought to be taken as crushing strength.

Aggregate Crushing Value and Its Test Procedure: One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS: 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on ...
