Abstract

This study shows that by using mixture-optimized, High Performance Concrete (HPC), significant reductions in CO2 contributions can be realized for concrete construction-in conventional buildings, as well as in major projects. There is a growing awareness all over the world about the extensive damages being caused to the environment due to accumulation of waste material in the form of pulverized fuel ash from thermal power plants, silica fume, blast furnace slag etc. Worldwide efforts are being made to utilize these industrial wastes as an alternative material for both in building industry and for road construction. The paper presents experimental studies conducted on HPC mix of M70 grade using mineral and chemical admixtures in various proportions. The main purpose of this investigation is to develop confidence among user agencies in India to use mineral and chemical admixtures in a desirable proportion in most of the construction works. Overall, the paper highlights the usage of admixtures to achieve high strength concrete mixes and from the experimental investigation it is clear that mineral admixtures contribute effectively a lot not only for achieving durability, also high strength.
