Effect on Partial Replacement of Fine Aggregate and Cement by Waste Marble Powder/ Granules on Flexural and Split Tensile Strength

Abstract

Marble as a building material especially in palaces and monuments has been in use for ages Many studies have been reported in literature on the performance of the concrete containing waste marble dust or waste marble aggregate. It can be seen that combination of marble dust and other ingredients has modulus or compressive strength higher than alone for 7 days and 28 days respectively. The use of high proportion of marble dust increases the strength of cement paste..This study shows the experimental investigations on the replacement of cement and sand both partially & combined with the waste marble powder/waste marble granules in which, by the partial replacement of cement and sand, the compressive, flexure and split-tensile strength get increased up to a certain percentage but get decreased with the combined replacement of combination of cement & sand.
