Compressive Strength of Concrete Hollow Blocks (Formula

Nov 16, 2017 · If the quality (determined by compressive strength) is greater than the regular hollow blocks, there would also be a comparison between the modified blocks (which of the three types would serve as a—possibly— greater alternative for the regular type)What is the normal compressive strength of hollow blocks?,The commpressive strength of hollow concrete blocks should be 5N/mm2 This strength is enough for the non-bearing wallsTesting of Concrete Masonry Blocks for Compressive ,Density of block (3 blocks) Compressive strength of block (8 blocks) Dimension Measurement All blocks should be checked in this step The length, width and height are measured with steel scale If it is a hollow block, then the web thickness and face shell are measured with caliper ruler
