In this study, the strength properties of marble powder in cement mortar have been investigated. The strength studies include compression test, split tensile test and flexure test. To perform these tests, a cement mortar is prepared in the ratio of 1:3 as per the Indian Standard guide lines. In this mortar, the cement is replaced by marble powder by 5%, 10%, 15%, 20%, 25%, 30%, 35% and 40%. For testing the compression strength behaviour of marble powder in replacement of cement, cement mortar cube specimens of size 7.07 cm x 7.07 cm x 7.07 cm are cast for all the said replacement ratios. After 7 and 28 days of curing, the specimens are tested for compression. Similarly for testing of splitting tensile strength, cylindrical mortar specimens of size 60mm dia. and 120mm are cast and tested at 7 and 28 days. For flexural strength determination, beam specimens of size 160mm x 40mm x 40mm are cast and these specimens are tested after the required days of curing. From the test results, it has been found that the cement mortar mix with 10% marble powder gives better results in compression, split tension and in flexure results. To determine the oxide composition of marble powder, XRF test was performed.
