Abstract
Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Marble has been used as an important building material, especially for decorative purposes for centuries. During sawing, shaping and polishing process, about 25% of the processed marble turns into dust or powder form. It is obvious that the waste material of these plants reaches millions of tons, thus making the stocking of this amount of waste impossible. Common river sand is expensive due to excessive cost of transportation from natural source. Also large scale depletion of this source creates environmental problem. Environmental transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product for concrete industry need to be found. The production of M-Sand also generates high percentages of micro fines, particles that pass the 75µsieve, ranging from 5% to 20%. In the present investigation, micro level materials such as Marble Powder (MP) are used to replacement of cement. Fine aggregate are replaced by Manufacturing Sand (M-Sand) and their physical properties were determined.It has been observed that at optimum value of 75% M-sand and 5% Marble powder, the compressive strength was increased by 17.37%, the tensile strength was increased by 53.6% and the flexural strength was increased by 20.64%.
