摘要：This paper gives you view to study the properties by using Recycled concrete aggregate as partial replacement for natural coarse aggregate on the properties of Self Compacting Concrete (SSC) in hardened state with different proportions. Compressive strength test is done for 7 and 28 days.SCC has favourable characteristics such as high fluidity, good segregation resistance and the distinctive self compactibility without any need for vibration during the placing process and so noiseless construction. The unique characteristics of SCC are a rapid rate of concrete placement with very less time. SCC offers a very high level of homogeneity; minimize the concrete void spaces and have uniform concrete strength and also provides the superior level of finishing and durability of structure. SCC also achieves same engineering properties and durability as traditional vibrated concrete. The use of SCC has gained a wider acceptance in recent years. Recycled aggregates (RA) are produced from the reprocessing of mineral waste materials, with the largest source being the construction and demolition waste. In general, the quality of RA is inferior to those of natural aggregates. In experiment, three types of concrete mix were made, where the percentage of substitution of coarse aggregate by recycled aggregate was 0%, 25% and 50% is varied. Determined the influence of different proportion on the performance of concrete made with coarse recycled aggregate from stamp out concrete. The properties analysed in Hardened properties. This paper explains the utilization of Recycled concrete aggregate in properties of Self Compacting Concrete. SCC is type of concrete with very high level of homogeneity; minimize the concrete void spaces and have uniform concrete strength and also provides the superior level of finishing and durability of structure. SCC also achieves all same engineering properties and durability as the traditional vibrated concrete we use on construction. The use of SCC has gained extensive acceptance in recent years.
