2014-4-20 The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.

Why cube strength is more than cylindrical strength? Cubes are based on BS code and its strength is higher than cylinders because of the platen effect of cubes.Generly,cube strength is 20 % higher than cylinder strength. What is a cylinder test? The Cylinder test is designed to evaluate locomotor asymmetry in rodent models of CNS disorders. As the animal moves within an open

When assessing the compressive strength of concrete, three test cylinders are required for each test from the same sample of concrete. This may be reduced to two specimens when analysis of strength results shows that the within test coefficient of variation is less than 4% as defined by NZS 3104 and NZS 3112 Part 2.

Test Procedure of Compressive Strength of Concrete Cubes: There are two types of specimens either cubes of 10 cm*10 cm*10 cm or 15 cm*15 cm*15 cm both depend on the sizes of aggregates used. Commonly size of 15 cm*15cm*15 cm cubical molds are used for most of the works. Concrete is poured and suitably forced so that there will be no voids.
