Determine the Compressive Strength of Concrete Hollow Blocks

2016-8-6  Concrete Hollow Blocks (CHB), are one of the most extensively used walling materials in the Philippines. Some of the reasons for this is their relative low cost when compared to other materials and speed of installation by semi-skilled labourers. CHB walls are very weak against lateral loads (pushing or pulling forces from typhoon or earthquake).

Experimental investigation on tensile strength of hollow ...

2021-8-2  In this paper, an experimental and statistical analysis was carried out from hollow concrete blocks. Firstly, 30 blocks were tested under compression force (vertical-direction). After, 60 blocks were studied under the splitting test from ASTM–C–1006 and, later a direct tensile test was applied to other 60 blocks. The blocks, in the direct tensile test, were subjected to a tensile force in ...
