Analysis on characteristics of self compacting concrete using recycled aggregate: A review

The inclusion of SCC or self-consolidating concrete is an innovative way to capitalize onthe demolished coarse aggregates in concrete. This can be obtained by crushing of old concretespecimens, beams, slabs, etc. This methodology was first introduced in Japan due to the scarcity andunavailability of labor. Since then it has gain popularity and has become a trend in the constructionsector. Its characteristics and properties are more or less similar to that of conventional concrete. Theflowability is good and there is no segregation of materials. It eliminates the vibration or any sort ofcompaction method which makes it easier to operate and perform in SITU. The durable propertyoffers rehabilitation such as repair applications. In this work SCC along with Recycled CoarseAggregate (RCA) is used in various proportions. The results are obtained and compared fordetermining the best proportion that can be adopted for practice. SCC, when incorporated withRecycled Aggregate (RA), showed a drop in compressive strength at various curing periods. Apartfrom mechanical properties, other various factors are discussed such as durability and microscopicanalysis. This will help in understanding its scope in the future
