2.1.4Compressive strength test Compressivestrengthis one of the key characteristics of concrete. It is affected by several factors, such as the shape of the aggregate, the mixture of materials, the water-to-cement ratio, and the cement’s strength and quality. A cube or cylinder is used to...
Wrapping of fibre over the concrete columns significantly improves the compressive strength and ductility behaviour of columns. In this study the compressi
For other values of compressive strength of concrete under different dimensions, they would be first transformed by the formula of Neville [32], as shown in the following equation: (1) where P is the compressive strength of concrete under other dimensions; P0 is the compressive strength of ...
will deserve more investigation in the near term in order to better check, on one side, the reliability of the proposed simplified models on the basis of more experimental data and, on the other side, the effective importance of considering the contribute of the mortar in the strength formula...

Besides, the academy used the hollow cylinder as a specimen to test biaxial compression and the strength varied from 1.52 to 1.67 of the uniaxial strength with different stress ratios. The test results of the biaxial compressive strength of Kupfer of West Germany were from 1.18 to 1.27 of the...
