  • This study is to analyze the difference by comparing the physical properties of general Portland cement (OPC) and low-heat Portland cement (LHC) in the market to develop low-heat cement manufacturing technology that can minimize the amount of limestone by using non-carbonate circulating resources as raw materials. To this end, the mortar is being reviewed by evaluating the properties of the mortar, such as slump, strength, durability, and thermal insulation properties, with a difference in the mixing ratio.
