Experimental Investigation on Strength, Porosity, and Permeability Properties of Ambient Cured Metakaolin-Based Geopolymer Concrete
Geopolymer concrete is the advancement in the construction industry towards the development of the world to a sustainable and greener environment. Since cement production contributes to the carbon footprint, an alternate greener product developed to overcome this environmental issue is geopolymer concrete which involves no cement and polymers binding with the industrial by-products to produce a strong binding material. Many industrial by-products can be used to produce geopolymer concrete such as fly ash, grounded granulated blast furnace slag (GGBS), rice husk ash (RHA), metakaolin (MK), etc. Metakaolin is a clay mineral of kaolin which is in dehydroxylated form and acts as a good supplementary cementitious material. In this study, geopolymer concrete is produced using the alkali activator sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) mixed with various replacement levels of metakaolin (MK) with GGBS cured under ambient temperature. Porosity is an important property that affects the strength and durability of the concrete. Sorptivity and volume of voids tests were conducted to assess the effects of porosity and permeability in geopolymer concrete constituting under ambient curing. The mechanical properties, sorptivity, and volume of voids test results show that better performance of geopolymer concrete can be achieved with 40% replacement of MK with GGBS under ambient curing than controlled concrete.
