Eco-cement
Eco-Cement is a brand name for a type of cement which incorporates reactive magnesia (sometimes called caustic calcined magnesia or magnesium oxide), another hydraulic cement such as Portland cement, and optionally pozzolans and industrial by-products, to reduce the environmental impact relative to conventional cement. Eco-Cement can include more industrial by-products as aggregate than Portland cement because it is much less alkaline, reducing the incidence of alkali-aggregate reactions which cause damage to hardened concrete.
