A study of the properties of mortars and bricks and their relation to bond

The water retaining capacity, transverse and compressive strengths, sorption, volume changes, and moduli of elasticity of 50 mortars and the absorption rate, moisture expansion, and transverse and compressive strengths of six makes of brick were studied.Also, 15 of the 50 mortars were used with the 6 makes of brick in tests of brick, mortar assemblages.The data indicate that the water retaining capacity of mortars and absorption rate of bricks were of primary importance in obtaining a good bond.The possible effects of brick and mortar properties on strength of bond in tension, bond durability, transverse strength of brick beams, and compressive strength of brick piers are discussed.
