Performance Characteristics of Self-cured Recycled Aggregate Concrete with SCM’s

Self-cured recycled aggregate concrete with shrinkage reducing admixtures is one of the pioneering researches in the construction industry. There is a possibility of depletion of natural resources due to prolonged consumption over a period of time in our modern civilization. In this research, characteristics of recycled aggregate concrete with supplementary cementitious materials (SCM) like powdered limestone and fly ash with self-curing agent PEG6000 were investigated along with the conventional concrete. Hydration plays a predominant role in the properties of hardened concrete. Particularly in high strength concretes, micro cracking occurs due to the absence of pore water and lack of relative humidity thus causes self-desiccation. The experimental studies exhibit the performance of concrete mixes with 35% limestone powder in LP60 and 35% fly ash in SC60 and RA60. The mechanical and durability properties of M60 concretes with SCM’s and PEG6000 were investigated. The results indicated that concretes with 1% self-curing compound shows improved results than the mixes with 0%. All the concretes mixes achieve the properties at the range of self-compacting concrete in the green state.
