COMPARATIVE STUDY OF PROPERTIES OF CONCRETE MADE OF HYDRAULIC CEMENT (TIS 2594) AND ORDINARY PORTLAND CEMENT (TIS 15)

Abstract

Cement is the most manufactured product in the world by mass and it is the 2nd most used substance after water. Cement industry alone is responsible for more than 5% of global CO2 emissions. Hydraulic cement (HY) with lower clinker content than ordinary Portland cement (OPC) can help reduce emissions, but with reduced clinker content performance and durability may become an issue with large scale adoption to significantly reduce emissions. This research was focused to answer questions on performance of concrete made of hydraulic cement versus OPC. Three major cement manufacturers in Thailand with combined market share of more than 85% were chosen and their brands of cement had been studied in this research. The study covered fresh, hardened and durability properties of concrete. The results obtained displayed that hydraulic cement concrete had workability similar to OPC concrete and compressive strength similar to OPC concrete and in some brands even better. With respect to durability, both hydraulic cement concrete and OPC concrete had similar properties.
