Compressive Strength and Elasticity of Masonry Prisms with Clay Brick and Flyash Brick

Most of the investigations on behavior of brick masonry are with burnt clay bricks. Yet, over the past few years, use of fly ash bricks has increased. The mechanical properties of masonry with fly ash bricks have to be studied. In this experimental research, brick masonry specimens were subjected to uniaxial compression. Fly ash and burnt clay brick prism specimens were cast in cement sand mortar with ratios as 1:4, 1:6, and 1:8. The specimens with four different h/t values between about 1.5 and 2.6 with number of mortar layers as 3, 4, and 5 were prepared. Analysis of the compressive strength test results showed that the masonry prism strength to unit brick strength ratio is higher with the fly ash bricks. The modulus of elasticity of the masonry is also higher with the fly ash bricks.
