In this paper an investigation of marble powder (MP) as partial replacement for cement and marble waste (MW) as partial replacement for sand is presented. MP replaced the cement at the rate of 5%, 10% and 15% of cement by mass. MW was used as a replacement for sand at constant 50% replacement level. Control mixture was prepared without MP and MW. Water to cement (w/c) ratio varied since MP was considered as binder, thus w/b ratio was constant. Fresh properties were determined by air content, workability and density, while hardened properties were evaluated with compressive and flexural strength, absorption, bulk density and quality. The results indicate a small decrease in workability, but no significant change in compressive strength for samples with 5% and 10% MP addition and 50% MW addition. Increasing the MP replacement level leads to a decrease in properties.
