Effect of admixtures and supplementary cementitious material on mechanical properties and durability of concrete

Abstract: We studied the effects of superplasticizer (SP) (PCE1 and PCE2), air-entraining admixtures (AEA), and supplementary cementitious material (silica fume and fly ash) on the mechanical and durability properties of concrete samples. Eight concrete mix designs were prepared. The first six concrete mix design contained similar aggregates, PCE2 SP, AEA, 350 kg/m 3 cement, and water to cement ratio equal to 0.38, and one of the mentioned mix design was selected as control samples with water to cement ratio equal to 0.… Show more

“…Silica fume, fly ash, metakaolin, and blast furnace slag have a composition that contains a high percentage of silicates. Silicates can react with Ca(OH)2 in the presence of some agents to improve the mechanical properties of concrete and reduce the porosity [7], [9], [11]. Another benefit that SCMs can provide, which is reducing the impact of structures being exposed to high temperatures up to 400 ºC by improving the residual compressive and tensile strength [12].…”

“…A study on concrete using natural zeolite as a partial substitute for regular Portland cement of 53 grade with coarse aggregates of 10-12 mm, fine aggregates, zeolite, and water was carried out. Compressive strength tests were performed on 150 * 150 * 150 mm cubes for 7, 14, and 28 days [22]. In this study, the physical-mechanical characteristics of zeolite and cement and the chemical and mineral parameters of fine and coarse aggregates were estimated.…”
