Vulnerability Assessment of Geo Polymer Concrete

摘要

World's most smart revolutions are from the construction industry, making sustainable developments in the construction industry lead to healthy environment. Cement is the major material required for construction purpose. In fast growing areas there is a more need for the occupancy, which ultimately results in the increase in the production of cement, for every production of 1 KG of cement there is 980 gms emission of carbon dioxide, which is the major contributor of green house effect and global warming, by considering the aspects in more eco friendly way there will be always a tenable solution to it. Due the revolution in construction industry, there is a vast research going on to find the alternate material to cement. One of the alternative material I prefer In this research paper is alkali activated fly ash slag recycle concrete (AAFSRC). The performance of AAFSRC with sodium hydroxide and potassium hydroxide, as alkali activators are studied. All the activators are used at 4% Na2O (by weight of slag). The scope of the work covered four mixes: a normal strength OPC control mix, potassium hydroxide activated fly ash-slag, sodium hydroxide activated fly ash-slag, combination of (NaOH +KOH). The results are given for 3, 7, 14 and 28 days.
