Abstract :

In this research, the effect of the cement, sand, and pumice mixture on the durability of lightweight concrete is investigated. The intention of this paper is to replace a certain amount of the pumice percentage as an alternative option of the cement and pumice sand aggregate with conventional sand components. The experimental results include compressive strength, ion-chloride emission factor (RCPT and RCMT). The experiments are carried out at the concrete age of 28 and 90 days. The results indicate that pumice composition improves the durability of lightweight concrete. Furthermore, it was observed that the proposed mixing design have proper permeability resistance against the chloride ion attack. For 90 days aged concrete, it was notified that the samples had a chlorine ion penetration coefficient of 10% which is less than the concrete specimens of 28 days. Finally, the compressive strength of the new mixing design samples can beincreased by 1.5 to 2.5 Mpa after 90 days.
