A STUDY OF COMPRESSIVE STRENGTH OF MORTAR MIXING …

From Fig. 2, it is found that the compressive strength of mortar is proportional to age of curing. When the quarry dust is added, the compressive strength is increased. This is because the quarry dust is stronger than sand. Moreover the seizing of quarry dust is larger than sand and fineness modulus is higher than sand (1). Then adding with quarry

Mortar Compressive Strength - Civil Engineering Knowledge Base

May 04, 2019· May 03, 2019· Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.
