An Experimental Study on Strength and Durability Properties for Utilization of Rice Husk Ash (RHA) in Geopolymer Concrete
Among many environmental issues, carbon dioxide released into the atmosphere takes a serious effect at the time of manufacturing the cement. Cement-less binder is an elective material to prevent the earth from global warming. Utilizing pozzolanic-filled industrial waste as source material can decrease the pollution from depravity of environment. Presence of chlorides in the building is the root for causing corrosion in reinforcement and degradation of the reinforced concrete structures. In this paper, tertiary materials such as fly ash, ground-granulated blast-furnace slag, and rice husk ash are employed and activated with 10 Mof NaOH. The results showed that replacement of fly ash by 30% of RHA improves the mechanical properties. Water absorption, sorptivity, and carbonation test are examined to study the durable nature of rice husk ash-based geopolymer concrete. The durability test results exhibit that RHA-based geopolymer concrete enhances the durable properties of concrete by making denser structure by providing strong bonding among the aggregate and paste which resulted in diminishing the water permeability.
