Ordinary Portland cement and lime are two traditional admixtures that account for 6% of all CO2 emissions, thus making them the leading causes of global warming. Alkali-activated slag types of cement are new environmentally friendly cement types that

Seismic analysis of earth and rockfill dams is generally done in two ways: quasi-static and dynamic. However, a quasi-static method with easy application and simple assumptions may lead to unsafe and uneconomical results. In the present study, two st
