Abstract:

Concrete is an important material used in constructions like buildings, pavements, bridges etc. often subjected to environmental impact loads. The durability of concrete and strength of concrete are affected when the concrete is exposed to fire accidents in the buildings and at high temperature in case of concrete pavements. This paper presents the results of experimental studies conducted on performance of High Volumes of Slag Concrete (HVSC) exposed to elevated temperatures up to 600oC. In HVSC, 50% of cement is replaced with Ground Granulated Blast Furnace Slag (GGBS). In this experimental studies, HVSC of 100 mm cubes are cast and tested for various water/binder ratios ranging from 0.55 to 0.27. The specimens are exposed to elevated temperatures of 200oC, 400oC and 600oC for 4, 8, 12 hours. Result of compressive strengths and weights of cubes after expose to high temperature are estimated. Percentage loss in compressive strengths and weights are also evaluated. The results illustrate that the loss in compressive strength and weights are more for higher temperatures for longer duration for higher water/binder ratios.

Keywords:

High Volumes of Slag Concrete, Ground Granulated Blast Furnace Slag, elevated temperatures.
