Abstract
This study investigates the sustainability performance of local common raw clay as a supplementary cementitious material (SCM) in concrete in simulated semi-arid environment of Morocco. The service life of the underground concrete pipe is shorter in this harsh environment because of aggressive corrosive soil, and cyclical variation of temperature and humidity. Limestone cement calcined clay (LC3 ) and limestone cement fly ash (LCF) and traditional OPC (Ordinary Portland cement) have been investigated. The electrochemical resistance, environmental, and economical performances have been evaluated. In the simulated condition, the LC3 improve good concrete performance (Rc) in simulated condition by approximately 25 and 3 times compared to LCF and OPC, respectively. The environmental and economical assessments of LC3 and LCF binder showed a similar cost and embodied CO2, and both concrete mixes were lower by 38% and 38%, respectively, than the traditional concrete. Ultimately, the LC3 technology seems to improve eco-friendly sustainability performance in the simulated aggressive semi-arid environment.
