Influence of Temperature on the Fracture Parameters of Basalt Fiber Concrete

Abstract

bstract: In the present study, the effect of elevated
temperatures on the strength parameters and fracture
parameters of plain and basalt fiber high strength concrete was
studied at the end of 28 days of conventional curing. The study
was done for 1000C, 3000C, 5000C, 7000C and 9000C
temperatures for 02 hours in a high temperature furnace of
10000C capacity. The percentage decrease in strength
parameters and fracture parameters was increased for plain
and basalt fiber concrete specimens with the increase in the
temperature.
