Experimental study on axial compressive strength and elastic modulus of the clay and fly ash brick masonry

Abstract

Brickwork is a composite material with bricks as the building units and the mortar as the jointing material. When this two element combined to form a brickwork unit, the properties of the materials influences the strength of the brickwork. Short prisms have been tested under axial compressive load using two types of masonry units: clay brick and flyash brick using flyash cement mortar. The brick masonry is reinforced with woven wire mesh at the alternate bed joint and tested for its axial strength and elastic modulus of the prisms specimens. They confirm that masonry prisms may be used for determining the basic compressive strength. Areas needing further investigation include the effect of moisture on the strength of brick masonry and the strength of eccentrically loaded brick work. In the present research, design strength was determined. Key words: Prism, flyash, mortar, brick masonry, elastic modulus.
