Effect of Potassium Hydroxide As An Activator on Compressive Strength of Activated Class F &Class C Fly Ash

This research paper highlights the details of development of variousphysical properties of geopolymer with respect to time. Compressivestrength and sorptivity arethe most important physical properties which are broadly discussedbelow. Fly ash is the main constitute material of this Geopolymer. Sothis investigation here is basically based on the three types of thefly ash which is Class F (Black), Class F (Gray) and Class C (White)respectively. Apart from fly ash potassium hydroxide and sodiumsilicate are the two main constituents materials used here. Fly ashchanges in silicate modulus and in percentage of K2O have also made anobvious impact on it. Again the changes in compressive strength withtime variation graphs strongly focus on the above statement. So, thispaper represents the very changes in physical properties of geopolymerdue to the application of potassium hydroxide, changes in silicatemodulus and in percentage of K2O with respect to time.
