Concrete cube test is a small quantity of concrete batch is taken out as a sampling for testing of compression strength of the concrete whether is achieved as per design required. The samples in cube sized of (150x150x150)mm Concrete’s compression strength is set under the grading(G)- Exp: G20kN, G25kN, G30kN etc. The concrete cubes are tested on days 7th, 14th, and 28th after its cured in the water. If a result of the strength/grade is below to the design mixed, that means a certain concrete ba
