Flexural behavior of RC structural elements made by geopolymer concrete

Abstract

The conception of Ordinary Portland Cement (OPC) diffuses CO2 into the air. Fly ash, which is a result acquired from coal industry, and replacement of OPC utilized in the construction. It is rich in silicate gel with alkaline solution to produce great cement. Expansion in fly ash fineness progresses the compressive strength and reduces the porosity. This investigation aims to study the flexural behavior of geopolymer concrete of M 30 grade and compares the same with OPC beam and column, to obtain the required compressive strength, 15% of GGBS is added to fly ash used in GPC, six (4GPC+2OPC) reinforced concrete beams and columns of size 150mm × 150 mm × 1200 mm were tested and cured under ambient temperature. Geopolymer concrete was made from flyash and ggbs which are byproducts of steel and thermal industries. The outcomes show that there is a rise in flexural strength, service load and peak load of GPC beams and columns than OPC beams and columns.
