concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.). Coarse aggregates (Fig. 5-2) consist of one or a com-CHAPTER 5
The use of waste marble powder (dust) was proposed in partial replacement of cement, for the production of Mortar and Concrete Mix. In particular, tests were conducted on the mortars and concrete mix cured for different times in order to determine their .
Gray cement obtains its color from raw materials that contain iron, manganese, chromium and magnesium oxides. To produce white cement, manufacturers must use limestone or other raw materials that contain very low levels of these oxides. White concrete cement must contain aggregates, such as marble, that do not add color.
Hence the maximum replacement of sand by admixture marble powder is 10 and 15 flexural strength increase.8.Conclusion the aim of the study was to evaluate durability of performance of structure concrete containing marble powder from marble quarriyng.After the experiment the following conclusion of concrete.1.15 marble powder.
