This paper presents an investigation into the efficiency of temperature-sensitive self-compacting concrete. Reviewing on self-compacted concrete, steel fibre, glass fibre, Polypropylene fibre. To this end, adding fibres (steel fibre, glass fibre, Polypropylene) content 1.2% for mixture of concrete material. When the cube samples were 28 days old. They have been heated to high temperatures. Each samples were heated to different temperatures for each concrete mixture (0ºC,100C, 200ºC). Then, Tests for weight loss and compressive strength were performed. The Observations of surface cracks were made after exposure to high temperatures. A significant loss of strength up to 30-40% for all concretes after 300ºC was observed, especially for concrete containing Polypropylene fibre, glass fibre, steel fibre. The fibres reduced the risk of explosive spalling and prevented it. Based on the results of the study, the output of fine aggregate concrete can be inferred.

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 100oC 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.
