In an extensive research scenario, the self-compacting concrete influence a major role in the advanced construction technology which gives the higher impact on its strength and durability of the structure, for its assessment there were various types of physical and chemical testing techniques are available. In this article the work represents the compressive strength of self-compacting concrete in various temperature testing like 200o C and 400 o C with the consideration of 100% cement and different mix proportion of admixtures for the replaceable of cement like Fly-ash with 30% and 15% and GGBFS 30% and 15% and the addition of polypropylene fibre with 1% and 2% with all of its mix proportion. The fundamental tests of the concrete are performed as per the Indian Standard code. The results indicate that an enhancement of compressive strength at the maximum optimized temperature.

SCC has been widely adopted in the various applications. Addition of fibers to SCC has shown to increase the strength and concrete durable. Concrete structures are subjected to intense solar radiations and alternating temperatures throughout their lifetime right from the time of casting. The variation in the properties of concrete due to this radiation exposure and thermal cycles of alternating hot and cold temperatures needs to be investigated. The current study presents an investigation on compressive and flexural strength as well as weight reduction in polypropylene fiber reinforced SCC at 100 o C thermal cycles of 7, 14 and 28 days. Two mixes of concrete namely normal SCC and SCC with mineral admixture (10% silica fume) are considered. Strength is observed to improve with an increase in thermal cycles while the weight is found to reduce.
