Abstract:

This paper presenting an experimental investigation has conducted on shear behavior of M-sand based geopolymer concrete, in this study low calcium flyash is used to make geopolymer concrete along with sodium hydroxide, sodium silicate solutions. The experimental study included a total of 5 beams and 12 cube specimens are casted, beam of size 100 x 150 x 1200mm and cube of size 150 x 150 x 150mm. All the Beams were provided with same amount of flexural and shear reinforcement and the beams were tested for various replacement of river sand by M-sand under two point loading.This research study focuses on complete elimination of Portland cement for production of concrete that can be achieve 28 days strength in the range of 40-44Mpa only under the sunlight curing. From this result geopolymer with M-sand beam shows higher compressive strength alsothebehavior of reinforced geopolymer concrete beams and M-sand based geopolymer concrete beams failing in shear, including the failure modes and crack patterns are found to be similar to those observed in reinforced Portland cement concrete beams including M-sand beams. It has found that the methods of calculation including code provisions, used in the case of reinforced Portland cement concrete beams are applicable for predicting the shear strength of reinforced geopolymer concrete beams. Being the fact that flyash and M-sand is considered as a waste material, so flyash and M-sand based geopolymer concrete is 30% cheaper than Portland cement concrete.
