Flexural Behavior of Tbsfrc Subjected to Sustained Elevated Temperature

Dr Deepa A Sinha

Abstract :

A detailed investigation is made to study the flexural behaviour of steel fie reinforced concrete with ternary blends on the beam specimen when subjected to sustained elevated temperature of 200oC, 400oC, 600oC, 800oC and 1000oC for 3 hours and then allowed to cool. The mix design was carried out for M30 grade concrete which yielded a proportion of 1:1.86: 2.41 with a w/c ratio of 0.45. Before mixing, 30% of cement was replaced by (FA + SF) or (FA+GGBFS) or (FA+MK) according to the proportions such as (0+0), (30+0), (25+5), (20+10), (15+15), (10+20), (5+25) and (0+30) respectively. It has been found that the TBSFRC containing (FA+GGBFS) and (FA+MK) offer higher resistance to sustained elevated temperatures upto 600oC and 800oC, where as the blend containing (FA+SF) offers resistance only upto 400oC.
