EXPERIMENTAL INVSTIGATION ON STRENGTH PROPERTIES AND SULPHATE RESISTANCE OF SELF-COMPACTING CONCRETE INCORPORATING SILICA FUME AND METAKAOLIN

Abstract

Self-compacting concrete (SCC) may overcome obstacles and be poured without vibration. Due to its benefits, SCC has grown in popularity in Japan, Europe, and the US since 1988. SCC technology may reduce or eliminate concrete laying issues in tough situations. It also saves time and effort by reducing quality control test repetition. Faster and simpler construction and placement. Not vibrating reduces noise pollution. SCC increases concrete durability, particularly in components with reinforcing congestion or permeability faults. The compressive and splitting tensile strengths and sulfate resistance of silica fume and metakaolin self-compacting concrete will be examined in this research. Silica fume and metakaolin may substitute cement in 5%, 10%, and 15% amounts. Samples are tested for sulfate, cracking tensile strength, and compressive resistance. The seventh, 28th, and 56th days of life are tested. This experiment using silica fume and Metakolin self-compacting concrete passed all plastic stage tests. Hardened-stage compressive and splitting tensile strength testing was also good. The compressive strength increased 18–38% with Simica fume and 15–45% with metakaolin. By replacing cement with silica fume and metakaolin, SCC's sulfate resistance increased.
