AN OVERVIEW ON GEOPOLYMER OR ALKALI-ACTIVATED BINDER ALTERNATIVE TO PORTLAND CEMENT AS ECOFRIENDLY CONSTRUCTION MATERIAL

Abstract

This review displayed, several extents of an alternative to Portland cement as Eco-friendly construction material to reduce CO2 emissions connected with the industry of the binder in concreting works and which are distributing as in general as follows: Replace the percentage of Portland cement with "low-carbon" supplementary cementitious materials (SCMs) in concrete. And development alternate low-carbon binders geopolymer or alkali-activated binder by Use alternative raw materials in the manufacture of concrete or mortar. The first path primarily reflects incremental improvements that can be completed relatively quickly and inexpensively as long as appropriate base materials can be identified. The second path is but also holds a potential pledge for really substantial reductions in CO2 if achieved on a large scale. If use SCM, as an alternative for cement. by use lowcarbon binders geopolymer for the manufacture of concrete or mortar.
