Abstract

An experimental study was conducted to study the effect of mortar thickness on the compressive strength characteristics of masonry prisms with solid blocks prototyped with granite dust (GD) and M-sand (MS). The solid blocks are produced by a constant replacement of cement by 10 % of granite dust and in replacement of fine aggregate by MS in proportions of 0%, 20%, 40%, 60%, 80% and 100%. The mortar grade (cement-sand ratio) used in the study is 1:5.Three types of mortar thickness were used in the study i.e., 10mm, 15mm and 20mm.The compressive strength of the masonry prism has been compared with code provisions i.e., IS1905-1987 and ASTM C 1314.It is observed that the thickness of mortar has marked effect on masonry prism. From the results, it is found that masonry prism of mix designation SGD10M40 with 15 mm mortar thickness achieved maximum compressive strength when compared with control mix (CM).
