Abstract

In recent years, research programs all around the world are concentrated on the improvement of sustainable construction materials. Because concrete is a building material, finding alternatives to OPC because of the high levels of carbon dioxide emissions involved with its production. The effects of Alkali activated solution (AAS) and fly ash on the fracture characteristics of fly ash-based GPC are examined in this study. Here, experimentation is carried on HSGC (High strength geopolymer concrete) and HSFRGC (High strength fibre reinforced geo-polymer concrete) which are having different notch depth variables as 0.25, 0.33, and 0.5. from test results and calculations from fracture energy it is noticed that, as notch depth ratio increases the load-bearing capacity reduces for Both type of beam specimens. It is also noticed that the addition of fibres in concrete enhances the loading bearing capacity, crack resistance and reduces the crack mouth opening displacement. Maximum fracture energy was obtained 1350.02 N/m for HSGC beam specimen and 1910.40 N/m for HSFRGC notched beam specimen and maximum peak loads are obtained for 0.25 notched beams followed by 0.33 and by 0.5 notched beams.
