To evaluate the tensile strength of concrete, a flexural test is performed on concrete beam. This test checks the ability of unreinforced concrete beam to withstand failure in bending. The flexural test on concrete can be conducted using 3-point load test. What are the Applications of Flexural Test on Concrete? Flexure test is an essential […]

How compressive strength of a concrete is determined?
To determine the compressive strength of concrete, 6 concrete samples are prepared using cube mould. Freshly prepared concrete is poured into 6 cube moulds and are kept for curing for 7 & 28 days. The preferred size of concrete cube used in concrete testing is 150mm x 150mm x 150mm. On 7th day, 3 concrete […]
How to prepare concrete cubes, using cube moulds, for testing?
Concrete Cube Mould preparation for strength testing Clean the cube mould thoroughly and oil it’s inner walls lightly. Freshly prepared concrete should be added to the mould and compacted with a steel tamping bar, with at least 30 to 35 tamps per layer for a 100 mm cube mould. Slightly overfill the mould and gently […]
