In this twenty-first century, Development is not only related to innovativeness in new applications but also reliability of infrastructural technology. Concrete is the main ingredient for the construction of infrastructure. When compared to other applied materials in the environment of concrete, its main component is cement. It is widely used in construction materials because of the raw materials present over the world. Nowadays Portland cement is the most popular cement concrete, but Global warming occurs due to the emission of the subsequent amount of carbon dioxide releasing quantity. So, to overcome this situation researchers are making a new step towards new alternative material named Geo Polymer concrete developed by Joseph Davidovits. It seems to be a potential alternative to standard concrete. In this we are using waste materials of combustion of coal powder waste flyash and Disposal of waste material eggshell powder for the full replacement of cement using the Reaction generating liquid with (flyash70% -eggshell 30%), (flyash80% -eggshell20%), (flyash90% -eggshell10%), (flyash100%eggshell 0%) compressive strength, split tensile strength, Flexural strength testing experiments are performed based on their proportions. This evaluating work mainly concentrates on the change in impact factor of silica modulus consisting of Reaction Generating Liquid (RGL)(Sio2/Na2o) ranging from 0.6 to 1.5.

This research work represents an investigation of the mechanical, durable properties and microstructure of geopolymer concrete mixed using Eggshell powder, class F fly ash (FA) and Ground granulated blast-furnace slag (GGBS). An optimal combination of FA, GGBS and Eggshell powder was determined using the compressive strength tests of geopolymer pastes and to find the durable properties like acid attack test and sorptivity test were conducted with various different replacements of FA with GGBS and Eggshell powder. The test results are to be taken on the mix proportions of geopolymer concrete various mix to be taken at 28,56, and 90 days respectively. This paper aims to examine the effects of chemical changes of reaction generating liquid on the strength and durable properties done to analyse the microstructure of the mortar through SEM, XRD, FT-IR and porosity assessments. The porosity analysis enabled us to indirectly verify the remarkable mechanical performance obtained by the activation of polymerization according to the chemical components of the Reaction Generating Liquid.

Researchers conducted research into the strength properties of a Geopolymer produced from eggshell powder, bauxite, and yash with RGL and curing for 84 days at ambient temperature. Also studied were changes in products of Morphology, XRD, FTIR studies and SEM images of microstructure. The results indicated that, in various mix proportions, the strength gradually improved from 28 days to 84 days. The aged geopolymer's lower porosity is attributed to the fact that the hardened samples become more compact with time due to gradual Geopolymerization to generate the coexisting C-A-S-H and N-A-S-H gels.Both the early-age and long-term Geopolymers had such an X-ray amorphous phase corresponding to Geopolymerization gel, but the aged specimens contain calcite from eggshell powder and alumina from bauxite powder, showing potential improvement on the properties of mechanical and durability properties were examined using various mix proportions in an experimental investigation.
