Concrete is one of the main material in the construction industry. The global cement industry contributes around 6% of all CO2 emission into the atmosphere. Global warming is caused by the emission of excessive greenhouse gases into the atmosphere hence reduce the environmental problems the cement is partially replaced by diatomite and waste marble powder. Diatomite is a pozzolanic material containing amorphous silica, cristabolite and minor amounts of residual minerals. Waste marble powder and marble stones is an inert material which is obtained as an industrial by-product during sawing, shaping, and polishing of marble. This waste is dumped on to open land which creates a lot of environmental problems and severe scarcity of natural aggregates for the production of concrete primary aggregates are partially replaced with marble aggregates. This paper describes the procedures and results of a laboratory investigation of mechanical properties carried out on the concrete specimens containing diatomite and WMP as partial replacement of cement and marble stones as partial replacement of coarse aggregate in concrete. Test results indicated that the best compressive and flexural strength of the concrete specimens containing 10% diatomite, 5% WMP and combination of 10% diatomite + 5% WMP replacement by weight of the cement and marble aggregate replacement to the coarse aggregate is 25% of the total volume of the aggregates together 10% diatomite + 5% WMP replacement by weight of the cement using a super plasticizing admixture to improve the mechanical properties of the conventional concrete mixtures. The main objective of this study is improving the mechanical properties of the concrete with low cost, economy and reducing environmental problems and global warming.
