Abstract
Sustainability in Cement mortar Production can be achieved by innovations in substitutions of materials used. Innovations are much needed to meet the increasing demand for new and quality materials. Use of Hazardous Industrial wastes in cement mortar and concrete making will leads to greener environment. This paper presents the feasibility of the substitution of waste granite powder for cement to achieve economy and environment saving. Granite waste is a solid waste material generated from the granite processing and can be used either as a filler material in cement or fine aggregates while preparing cement mortar and concrete. It has been used as a replacement of fine aggregates in many literature works but this paper presents the feasibility of the substitution of granite waste for cement in mortar to achieve economy and environment saving. But silica oxide content in granite tend to cause alkali aggregate reaction. So an attempt has been made to investigate the occurance of ASR in cement mortar. Properties of cement mortar incorporating granite powder(GP) as partial substitution for Portland cement in amounts of different percentage were investigated and the Compressive strength of Cement mortar is found to be be decreased with addition of waste granite powder .And also an investigation conducted to evaluate the influence of elevated temperatures on the mechanical properties of cement mortar (which contains GP).The effects of elevated temperature on mortar are noted and their performance were compared to control mix mortar. In this research,analysis of SEM and XRD was carried out to analyze the particle size and occurance of ASR .The production of cheaper and more durable cement mortar using this waste can solve to some extent the ecological and environmental problems. Therefore this paper provides a scope for more research which is required to design consistent and durable concrete with this waste.
