More## COMPRESSIVE STRENGTH FOR CONCRETE BLOCK

2015-4-24 For design of masonry, the compressive strength is current1y based on standard prism strengths, determined ei ther from testing of fully capped 2 block high prisms or from code vai ues tabulated according to the mortar type and block strength. However, standard prism strengths do not closely represent the true compressive strength of face shell mortared block masonry. This is because prism strengths determined from tests of fully capped standard 2 block high prisms are influenced by the significant loading platen restraint, non-representative full capping and an inadequate number of mortar joints to reproduce the mode of failure observed in structural elements. The compressive strengths tabulated on the basis ofblock strength and morta r type are influenced by the same factors beca use of being based on previous similar prism tests. An added facto r is that current standard methods of measuring the material properties do not accurately quantify the properties relevant to compressive strength of face shell mortared masonry. This leads to uncertainty regarding the relationships between prism strengths and the strengths
