Abstract

To decrease greenhouse gas emissions and maintain sustainable economic growth, the cement industry has developed limestone calcined clay cement (LC3). Many researchers have started to investigate the performance of LC3 as a construction material. However, the strength development of LC3 has diverging or opposite views. In this research, the strength development characteristics of ordinary Portland cement (OPC) and LC3 with different combinations of medium reactive ground granulated blast furnace slag (GGBFS) have been compared using compressive strength and ultrasonic pulse velocity, and maturity tests. The test result shows that the LC3 concrete has a similar 28-day compressive strength to OPC concrete despite developing a lower early age. Ultrasonic pulse velocity test results have matched compressive strength test results. The predicted compressive strengths using 7-day maturity data were comparable to actual strength results.
