GEOPOLYMER AS GREEN CONSTRUCTION MATERIALS RESEARCH describes about different important factors (e.g. NaOH molarity, activator-to-fly ash ratios, curing condition, etc.) influencing the processing of the fly ash-based geopolymer were investigated. These experimental results are utilized to propose a new method for geopolymer cement processing and the design of geopolymer concrete mixtures. Experimental data on the characterization and properties of the geopolymer cement and concrete are then presented. Some case study about the geopolymer materials also has been presented in this booklet. Final part of this book also describes the application of these geopolymers as lightweight materials, geopolymer brick, pilot plant for geopolymer brick/block making machine, and some preliminary study on geopolymer coating and aggregate.
