Abstract

Construction industry is exploring Green-concrete to reduce the use of concrete mixture (OPC). Global warming is caused by the CO2 emissions during cement production. Geopolymer concrete (GPC) has been put into practice as a replacement of conventional concrete. Granite waste is one of the industrial waste produced by the mining activity. Later, granite waste deposits become a problem for the environment. For the case of reducing granite waste, it must be used as a binder or fine aggregate in concrete. In the present analysis, fly ash in the range of 0, 5, 10, 15 and 20% is partially replaced by granite waste. Identify the effect of granite waste at 7 and 28 days of age on mechanical properties such as compressive strength and split-tensile strength in the initial stage. In the final stage the effect of granite waste has been studied at different ages on durability properties such as Sulphate attack, chloride attack, acid attack, Sorptivity, water absorption and carbonation. The non-destructive tests such as the Rebound hammer and the UPV tests were carried out at 28 days. Micro- structure of all mixes is studied by Electron Microscopy Scanning (SEM)
