Effect of Processing Parameters on Compressive Strength of Metakaolinite Based Geopolymers: Using DOE Approach

AbstractGeopolymers are inorganic materials with a wide variety of potential applications such as fire resistant materials, building materials, cements and concrete, high-tech composites aircraft interior, and etc. Various parameters affect the properties of these materials. This article describes the effects of several factors such as molar ratios of SiO2/Al2O3, Na2O/SiO2, and H2O/Na2O and curing temperature on the compressive strength of metakaolinite based geopolymer bodies (MGBs) by statistical design of experiments (DOE) approach. It was found that the above-mentioned agents play an important role in MGBs’ properties. Also, a model to present the relationship between compressive strength and influential factors was obtained
