Abstract

The performance of Light Weight Self-Compacting Concrete (LWSCC) incorporated with Sintered Fly Ash and Vermiculite are investigated in this study. The robustness and hardened properties of the LWSCC is investigated at diverse proportioning rates where Cement, Fine Aggregate and Coarse Aggregate are replaced with Fly Ash (FA) (25%), Vermiculite (1-9%) and Sintered Fly Ash (SFA) (10-50%) respectively. The workability properties such as Filling ability, Passing ability, viscosity and the mechanical properties such as density, compressive strength, tensile strength, flexural strength, ultrasonic pulse velocity, acid and sulphate resistance were studied. The percentage loss in weight and loss in compressive strength due to Acid attack and Sulphate attack at the age of 28 days of LWSCC were observed by immersing in 10% of HNO3, magnesium sulphate and sodium sulphate solutions. Vermiculite with SFA considerably boosted the workability and mechanical properties of LWSCC mixes. The presence of lightweight aggregates reduced the strength loss caused by sodium and magnesium sulphate ions. A combination of 5% of Vermiculite and 30% of SFA resulted with the best robustness and hardened property of concrete
