Mechanical Properties of Brick Masonry using Stone Dust as Partially Replacement with Sand in Mortar

This paper presents the experimental investigation of mechanical properties of brick masonry using stone dust as partially replacement with sand in masonry mortar. As part of research the main goal of work is to determine compressive strength, modulus of elasticity and bond strength of brick masonry specimen. The brick masonry specimen made with common building brick available in Ahmedabad region throughout the work and two different mortar proportions 1:3 and 1:6 (cement: sand) adopted. The water to cement ratio (W/C) 0.60 is constant throughout experiment work. Sand was replaced by sand stone dust of 0%, 25%, and 50% by weight of sand in mortar mixes for 7 days of tests and 0%, 20%, 30%, 40% and 50% replacement in mortar mixes used for the 28 days of tests. After completion of curing period, the mechanical properties were measured. From the experiment work, it was concluded that up to 30% replacement of sand stone dust with sand is possible and give reliable results.
