Compressive strength of concrete block in N/mm2

Compressive strength of concrete block in N/mm2 kg/cm2, on average, it range from 75 to 125N/mm2 or 75 to 125kg/cm2 for hollow/ solid CMU It is observed that the compressive strength of the blocks varies in a non linear pattern with the quantity of additive Initially the compressive strength increases until a peak value is attained and decreases thereafter The maximum compressive strength has been found to be 36 MPa for the value of additive quantity as 148%Compressive Strength of Interlocking Concrete Pavement Compressive strength of concrete Blocks or concrete masonry units are required to know the suitability of these in construction works for various purposes Concrete masonry blocks are generally made of cement, aggregate and water Which are usually rectangular and are used in construction of masonry Testing of Concrete Masonry Blocks for Compressive

Compressive strength and deformation characteristics

The compressive strength is one of the prime properties for the design of masonry walls in various loading situations Subsequently, several research studies have been dedicated in the past to investigate the compressive behaviour of concrete block masonry [,,,,,,, ]Hence, one can note there is an inconsistency in the approach of designing and constructing concrete block masonry with various mortar types in different codes of practice The random exclusion of specific mortar types for the determination of compressive strength of concrete block Compressive strength and deformation characteristics The compressive strength of AAC block masonry is less than that of the compressive strength of individual AAC block The average compressive strength of masonry using different proportions of cement–sand mortar ranged from 196–258 N/mm2 (MPa), whereas the average compressive strength of individual AAC block Compressive strength of AAC Block Test procedure
