ABSTRACT - Self compacting concrete (SCC) is a high performance concrete that can flow under its own weight to completely fill the formwork and self-consolidates without any mechanical vibration. Self-Compacting Concrete (SCC) has gained a wide use for placement in congested reinforcement concrete structures where casting condition are difficult and in high rise buildings where pump ability properties are required. The project aim is to use of marble powder as an industrial waste and Fly ash as a pozzolana material. The established benefits substitution marble powder and fly ash by cement to make concrete as economic by the use of less cement. The main objective of the project to carry out an experimental investigation to study the properties of SCC, by partially replacing cement with certain percentage of Fly ash and Marble powder and understand the effect on fresh property, Harden property and Durability and also investigate the compatibility of marble powders in SCC along with chemical admixture such as super plasticizers. The Mix Design for self compacting concrete M0 grade is being done as per the Indian Standard Code IS: 08. KEYWORD: Self compacting concrete, Marble Powder, Fly Ash, Mix design. INTRODUCTION SCC has been considered as a great development in construction since it s first developed in japan. The high fluidity is main property of SCC so that it can be placed under its self-weight without vibration. In order to obtain SCC of high flowability without segregation or bleeding during the transportation or placing, the use of high powder content, super plasticizers and viscosity modifying admixtures seems a good solution. However, the cost of such concrete is significantly higher. The use of mineral additives such as silica fumes (SFs), Fly ash (FA) and ground granulated blast-furnace slag (GGBFS) could reduce material cost and enhance the self-compatibility. Several studies have shown that natural pozzolana have been widely used as a substitute for Portland cement in many applications because of its advantageous properties which include cost-reduction, reduction in heat evolution, decreased permeability and increased chemical resistance. Marble powder (MP) which is an inert material obtained as an industrial by-product during sawing, shaping, and polishing of marble has also successfully been used as an addition in SCC. Marble powder used as mineral addition of cement is reported to improve some properties of fresh and hardened self-compacting concrete (SCC). Page

2 International Journal of Scientific Research in Engineering (IJSRE) Vol. (), March, 07 RESEARCH SIGNIFICANCE This paper describes a procedure specifically developed to achieve SCC, using mineral admixture like Fly ash and Marble Powder as a partial replacing material for cement. In addition, the test results for acceptance characteristics for SCC such as Workability characteristics (Slump flow, J-ring and L-Box), Mechanical characteristics (Compressive, Split Tensile,). The Materials used in the research are:. Cement Cement paste is the binder in SCC that holds the aggregate (coarse, fine, admixtures) together and reacts with mineral materials in hardened mass. The property of SCC depends on the quantities and the quality of its constituents. In this present work, Ordinary Portland Cement of ultratech conforming to IS: -87 has been used and tested for their properties, presented in Table.

This project describes the feasibility of using the marble dust in concrete production as partial replacement of cement. In INDIA, the marble and granite stone processing is one of the most thriving industry the effects if varying marble dust content on the physical and mechanical properties of fresh and hardened concrete have been investigated.. Water The water should be clean and free from harmful impurities. METHODOLOGY Experimental investigation is carried out to study the properties of SCC, by partially replacing cement with certain percentage of fly ash and marble powder. To achieve optimum SCC mix various trail mix are done by varying cement, coarse and fine aggregate, water and super plasticizer. Once getting the Optimum Mix Design, totally six mixes are done by replacing cement with fly ash keeping % constant and marble powder added in percentage by mass of cement as 0,,0,,0 and %. Experimental programme are carried out in two phase. In the First Phase, for each mix tests are conducted to assess fresh Workability properties (Slump flow, J-ring,, L-box test) of concrete. In Second Phase, fresh concrete are cast into cubes, cylinders and beams. Specimens are cured in water till testing for 7, 8 days, than are tested for Mechanical properties (Compressive strength, Split Tensile strength. MIX PROPORTION The portioning of the mix is extremely important in developing an effective SCC. Till date there is no specific code book for mix design of SCC, but EFNARC provides specification and guidelines. Using IS method for mix design of SCC. EFNARC Specification and Guidelines for SCC-00 Water / Powder ratio by volume of Total powder content of 0-0 lts (00-00 Kg) per cubic meter. Coarse aggregate content normally 8-% by volume of the mix. Typically water content does not exceed 00 lts/m. Fresh Properties of SCC The main characteristic of SCC is its properties in the fresh state. SCC mix design is focused on the flowing ability, under its own weight without vibration. The ability to flow through congested reinforcing bars under its own weight. And, the ability to maintain the homogeneity without segregation of aggregates. Page
