Plasticizers and Viscosity Modifying Agents (VMA) and does not needs compaction, removes air voids itself is known as Self compacting concrete (SCC). Due to well-controlled conditions, the initiation of SCC in the precast concrete is successful. But on the field, the growth is slower, as the product is more sensitive. In this paper the properties of SCC in comparison to normal concrete has been discussed
Later on many researchers worked on SCC to enhance the quality and strength of concrete. “

Mishra and Panda (2015) rubber particles were employed as aggregates in the production of concrete to improve the material's ability to absorb energy and to improve its tensile and deformation capacities. Aggregate rubber particles, it has been shown, enhance misshapening and energy assimilation limits while at the same time diminishing usefulness and mechanical elements.

1. INTRODUCTION
Gite.al. (2014) Steel fibres with varied aspect ratios were tested in a series of experiments, and it was shown that the strength of a given steel fibre decreased with decreasing aspect ratio, and that straight fibres had less strength than their hooked-end and crimped counterparts.
First created in Japan in 1986, self- consolidating concrete (SCC) is sometimes known as self-compacting concrete. The characteristics of SCC are the subject of much study. “
Shuttering concrete is unique in that it can flow into and fill every crevice of the formwork (without the aid of vibration or other void removal processes) even when substantial reinforcing is present. Use of recycled or waste materials for the construction of civil structures is a matter of great significance in this century. Utilization of Portland cement per unit volume of concrete is decreased when waste materials are used in building. The proliferation of SCC across the world, as well as its unique microsocial structure and strengths, have been the subjects of a great deal of study. The Bureau of Indian Standards (BIS) has not normalized a blend strategy to get proper blend plan preliminaries and self-reduced limit testing methodology, despite considerable research and building system efforts. Similar to regular concrete, Self Compacting Concrete's performance depends on the combination of a fastener, fine total, coarse total, water, fines, and admixtures. Significant purposes for the expanded utilization of strengthening materials in concrete cement are To diminish the utilization of concrete however supplanting the concrete with materials having cementations properties. to work on the properties of new and solidified concrete. A few researchers have as of late grown elite execution concrete with a low water-to-solidify proportion by utilizing super-plasticizers and ultrafine mineral admixtures.
Alberti. Et al (2014). Different macro polyolefin fibre contents in self-compacting concrete were tested, and their effects on the concrete's mechanical qualities were compared. Similar fracture behaviour is maintained when comparing these materials to self-compacting concrete with and without steel fibres. Balakrishnan and Paulose (2013) used fly ash as a cement replacement in four different percentages (12.5%, 18.75%, 25%, and 37.5%) and discovered that fly ash improved workability, reduced bleeding and segregation, and increased filling and passing capacities of concrete. "The ductile behaviour of SFRSCC has been modelled
numerically, thanks to the work of Cunha et al. (2011). The smeared crack model in three dimensions helps to establish the nonlinear material behaviour of self-compacting concrete. The mathematical model has shown a high correlation with experimental results. Vijayanand et al (2010) dissected the flexural reaction of SCC radiates built up with steel strands. Three plain SCC bars and six SCC radiates with steel fibbers with fluctuating percent of fibber content (0%, 0.5%, and 1.0%) and the pliable steel proportion (0.99%, 1.77%, and 2.51%) were given a role as a component of a trial program.
2. OBJECTIVE OF STUDY The main purpose of this study is to explore the possibility of utilizing waste products in concrete production and to compare the properties of SCC to normal concrete. ”
