Know More" The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall."
Know MoreA comprehensive series of drained triaxial compression tests were performed on crushed concrete aggregate (CCA) moist as compacted. When compared to ordinary natural wellgraded gravelly soils, the peak strength and stiffness increase more significantly with dry density, while the effect of the degree of saturation during compaction is much less significant.
Know MoreSAMPLING The first step is to take a test sample from the large batch of concrete. This should be done as soon as discharge of the concrete commences. The sample should be representative of the concrete supplied. The sample is taken in one of two ways: For purposes of accepting or rejecting the load: Sampling after 0.2 m3 of the load has been poured.
Know MoreConcrete cubes may get crushed on one side or will develop tensile crack on one or more faces and fail. Fig shown below shows some of the likely unusual failures of concrete cubes. This type of failure will give lower indiion of compressive strength of concrete. These are usually due to defects associated with testing machine.
