Geopolymer Concrete, Silica Sand, Two-Point Loading, Flexural Parameters


Many efforts are put on the advances in construction technology. Study on the Geopolymer concrete, which is produced by developing a binder named geopolymer are rich in silica and alumina as source materials by an alkaline reaction, it replaces Ordinary Portland Cement. This study mainly focused on the Flexural behaviour of geopolymer concrete One-way slab with partial replacement of silica sand as natural sand at different proportions like 100:0, 90:10, 80:20, and 70:30 (natural sand: silica sand). The grade of conventional concrete M40, which is equivalent to grade of geopolymer concrete. The Slabs were cured for 28 days at ambient room temperature and tested for two point loading. The flexural parameters under two point loading like Load characteristics, first crack load, Ultimate load, service load, yield load, Ultimate deflection, bending stresses, Moment characteristics are presented. The study final concludes that at 20% replacement level of silica sand as partial replacement of natural sand gives better results at 8M, hence the silica sand used as a filler material for well graded geopolymer concrete.
