Durability Properties of Self-compacting Concrete Using Silica Fume

Abstract

Vigorous industrialization has led to the voracious generation of waste materials, like silica fume, RHA, ferrochrome ash, fly ash and so on. There were alternative materials that can be used as mineral admixture to cement in concrete. For example, ferrochrome ash which was obtained from Ferro-alloy industries and fly ash which is produced in thermal power plants are a few of them. This research shows the combined effect of fly ash and ferrochrome ash-based concrete in different percentages as partial replacement of cement. This paper is inclusive of results of experiments that have been carried out to get the enhanced mechanical properties of OPC by replacing fly ash with various percentages (10, 20, 30 and 3%) of ferrochrome ash. It was observed from the research that even a small quantity of ferrochrome ash when mixed with 30% of fly ash increases the compressive strength than fly ash alone in concrete. Both ferrochrome ash and fly ash come categorically under industrial waste; hence by using this industrial waste reduces the production of greenhouse gas and helps manage dumping at large. This, at the end, is a method of producing sustainable concrete.
