Abstract
Concrete is one of the most versatile construction materials as it can be designed to withstand the harshest environmental conditions. This causes major problems for the environment due to CO2 emission from the manufacturing of Portland cement. Also, the fast growth in various industries has resulted in tons of by-product or waste materials, which can be used to replace cement, i.e., fly ash, silica fume, steel slag, etc. Silica fume is one of the best admixtures which improve the strength. Geopolymer concrete (GPC) is the alternative substitute of cement concrete. It can reduce global warming as well as solves the problems regarding industrial waste disposal. The main purpose of this study was to evaluate the mechanical properties of low-calcium fly ash-based GPC and silica fume blended GPC. To achieve this goal, 14 molar fly ash-based geopolymers and 14 molar silica fume blended GPC mixes were prepared. Present study indicates that the incorporation of silica fume in fly ash-based GPC has a significant effect on the development of its different properties. The compressive strength of GPC at 28 days varied from 20 to 38 MPa, and the ultimate strength reached up to 48 MPa.
