Behaviour of Masonry with Flyash Bricks

Abstract

Abstract Bricks will always be needed for construction, but as land use intensifies, soil for making bricks will become scarcer. Though fly ash bricks are available from last few years, but the experimental data regarding behaviour of masonry made with such bricks are limited. In the realm of structural design, the compressive strength of masonry stands as a crucial property, while the modulus of elasticity under uniaxial compression assumes equal importance, particularly when addressing concerns related to the deformation of masonry structures. The aim of the experimental investigation reported in this paper is to determine modulus of Elasticity (E) for fly ash brick masonry under axial compression through testing prisms with height to the least lateral dimension ratio of prisms between 2 to 4. Comparison of the same is reported with that of the masonry with conventional burnt clay bricks. The test results revealed that the strength and E of masonry with the alternative bricks (flyash) are in almost similar range to those with burnt clay bricks.
