Compressive strength of AAC Block

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 1.96–2.58 N/mm2 (MPa), whereas the average compressive strength of individual AAC block is ranging between 3 to 6 N/mm2 .
