| Popis: | The need for reducing the carbon footprint and effect of hazardous gases, etc., released from the construction sectors and other product manufacturing industries on the environment is the need of the hour. In this regard, the construction sector has been utilizing some of the wastes generated from various sources in making concrete. Notable among them is the Ground granulated blast furnace slag (i.e. GGBS) as a partial substitution of cement. Further, waste foundry sand, a by-product of the foundry industry is observed to be an appropriate alternative to partial replacement of fine aggregate and demolition waste as a partial replacement of coarse aggregate. These waste utilizations have addressed some of the global environmental concerns like solid waste management, scarcity of landfilling, sustainability etc. but there is still is inefficient, given the rate at which we are producing waste. This paper presents an overview of some of the recent research published on the utilization of wastes in the production of sustainable RMC/SMC. It also presents the effect of waste utilization in concrete on mechanical, microstructural and durability factors. |
