In order to avoid the deleterious impact on carbon dioxide emission from the production of cement, an alternative binding material by synthesizing the pozzolanic precursor (rich in Si, Al) is activated with the reagents of alkali/acidic medium through the exothermic process of geopolymerization. Geopolymer concrete (GP) is recognized as an alternative promising material to the conventional cement concrete. This research aims in investigating the performance of the physical-durability characteristics of the GPC produced from the natural mineral phosphate deposits, which is pulverized and utilized as one of the precursors along with the most endorsed prime materials, fly ash and ground granulated blast furnace slag. This combination had a leading chemical composition of Ca, Si, and Al which creates a sturdier internal dense matrix from the polymerization process to produce the oligo-silates gel structure, and this poly-condense forms the reticulation networking with the final product of geopolymer solidification. Based on the test results obtained in the aggressive environment exposure conditions, this concrete proved to counterpart the conventional OPC by enduring the acidic, sulphate and chloride environments and also able to withstand thermal exposure condition with minimal crumbling.
