Flexural Toughness of Ternary Blended Steel Fibre Reinforced Concrete Subjected to Sustained Elevated Temperature

Dr Deepa A Sinha

Abstract :

In this paper, an attempt is made to study the flexural toughness of steel fie reinforced concrete with ternary blends. 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. A detailed investigation is made to study the flexural toughness 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.. It can be concluded that 30% replacement of cement by (10+20) proportions of (FA+GGBFS) in ternary blended SFRC yields higher strength.
