Basic properties of non-sintered cement mortar using industrial byproducts as activators

Abstract

This paper investigates the basic properties of non-sintered cement (NSC) mortar produced using granulated blast-furnace slag (an industrial byproduct), phosphogypsum (PG) generated in fertilizer production, and slacked lime (SL) as a replacement for cement to reduce environmental load and carbon emissions. The experimental results indicate that NSC mortar using industrial byproducts and waste was initially weaker than mortar using ordinary Portland cement (OPC) but that there was a reversal in their long-term strength and durability. These results indicate that the use of NSC mortar can overcome various limitations of OPC structures and that further NSC research can facilitate the development and use of various alternatives to cement, which is one of the major causes of global warming.
