Environmental impacts and mechanical properties of ...

Jan 20, 2018 · The results indicated that RM can be used to produce LWC with convenient mechanical properties and densities of 1685–1789 (kg/m 3). Moreover, the environmental impacts of LWC incorporating 25% of RM reduced in terms of CED, GWP, CO, NO X, Pb and SO 2. Consequently, reusing RM waste which is otherwise disposed in landfills is an environmental ...
