Abstract

This paper presents an experimental investigation on the effect of high temperature on the properties of SCC produced by the combination of admixtures (Superplasticizer + Viscosity modifying admixture + Air entraining agent + Retarder). The concrete testing specimens was prepared by a mix proportion 1:2.7:6.1:5.1 with cement: fly ash: sand: coarse aggregate with a water/binder ratio of 0.38. After 28 days of curing all specimens were removed and weighed 0 0 0 0 accurately and kept in the oven where they were subjected to 100 C, 200 C, 800 C and 900 C as the case may be for 4 hours. The specimens after cooling were weighed again to find the percentage loss of weight and were thoroughly observed for their change in colour and cracks. These specimens were tested for their respective strengths for different percentage addition of last admixture. SCC produced with the combination of admixtures show better resistance to elevated temperatures.
