Experimental Investigation on Geopolymer Concrete Under Different Modes of Curing

Various researches are going worldwide to find a replacement to Portland cement, as it produces carbon di oxide next to the automobiles which highly pollutes the atmosphere. In addition to that large amount of energy was also consumed for the cement production. Geopolymer concrete is one of the best replacement for this issue which is pollution free and it is constitutent of many residual materials which need space to be dumped as waste. The reaction of materials containing alumino silicates with concentrated alkaline solution to produce an inorganic polymer binder is known as geopolymer concrete. It is emerged as a possible solution for using the by-products of many industries which could be utilized in manufacturing of precast structure and non-structural elements, concrete pavements, concrete products and immobilization of the toxic waste that are resistant to heat and aggressive environment. Sodium hydroxide solution of 8 Molar concentration is mixed with sodium silicate gel is used as alkaline solution. The project is to test the beam column joints prepared by geopolymer concrete of various molarity of 8M. Curing of member is done by various methods mainly open air curing, heat curing and ambient curing with thin film wrapping in which thin film wrapped curing produces more results conclusive. So further projects can be carried out by film wrap up curing in geopolymer structural elements as heat curing in structural elements is uneconomical and practically impossible.
