Comparative Analysis of Geopolymer Concrete with Conventional Concrete Using M Sand - A Review

World's most consumed construction material is concrete made up of cement, aggregates, water and additives as it is found to be more versatile, durable and reliable. Concrete is the second most consumed material after water, which required large quantities of Portland cement. The manufacturing process of Ordinary Portland Cement (OPC) results in destruction of the environment due to the emission of CO2 as well mining also results in unrecoverable loss to nature. The amount of carbon emissions is increasing on an alarming scale and hence, it is required to find an alternative material to the existing expensive cement-concrete. This is also a high time to think for an alternative to cement since the production of cement is the main reason for emission. There are considerable attempts which have taken place in order to replace cement other materials. Geo-polymer concrete is one of an alternative construction material which is produced by the chemical action of inorganic molecules. Fly Ash, a by-product of coal obtained from the thermal power plant is abundantly available worldwide. Fly ash which is rich with silica and alumina activated with alkaline activators form alumino silicate gel that act as the binding material for the concrete. It is an excellent alternative construction material to normal concrete without using any amount of ordinary Portland cement. Geo-polymer concrete shows a greener substitute for ordinary Portland cement concrete in some applications. This paper reviews the structural properties of Geo-polymer concrete and its applications. Hence, an attempt has been made to consolidate the research works carried out by the researchers in the area of geo-polymer concrete. The limitations of geo-polymer concrete are also presented.
