چکیده
Self-compacting concrete (SCC) is an innovative concrete that has been able to improve the problems caused by shaking operations during compaction and concreting in reinforced thin sections compared to conventionally placed concrete. Common pozzolanic materials used in concrete include fly ash, iron smelting furnace slag, rice husk ash, silica fume, pumice, and volcanic tuffs. One of the synthetic pozzolanic materials used in concrete in recent years is bagasse. Bagasse is a substance obtained after extracting the sugarcane stalk extract. Rice husk ash (RHA) produced from the controlled combustion process has a very high pozzolanic property, and this phenomenon is due to the presence of a high percentage of amorphous silica inside the rice husk. This article aims to investigate the mechanical properties (efficiency, compressive strength, and permeability) of SCC containing different percentages of rice husk ash and bagasse according to the variables of concrete age. Also, L-Box, V-Funnel, and Slump tests were used to measure the filling ability, creep, and permeability of the manufactured concretes and to confirm the self-compaction of the mixing designs. Compressive strength, permeability, and specific, gravity tests were also performed on the self-compacting hardened concrete of the control and modified with ashes. The results indicate that the use of rice husk ash and bagasse increases the compressive strength and specific gravity and decreases the permeability of SCCکلیدواژه ها
