Water-to-cement ratio (w/c) has been established at 0.45. In this experimental investigation, concrete cubes and split tensile cylinders will be used with varying quantities of vermiculite: 0%, 20%, 40%, 60%, 80%, and 100%. The compression and split tensile strength of vermiculite concrete specimens are analyzed after 7, 14, and 28 days of curing, revealing a substantial increase in strength. Instead of sand, vermiculite is employed as the primary infill in concrete. The self-weight of the structure will be reduced by utilizing fine aggregate in place of vermiculite. This leads to a decrease in the cost of construction. https://www.materialsciencejournal.org/vol22no1/experimental-analysis-of-vermiculite-concrete-with-supplementary-cementitious-materials-assessing-the-synergistic-effects-of-fly-ash-and-silica-fume/ Admixtures Curing Fly ash M30 Silica fume Strength properties Vermiculite
