Cement an intensive energy construction material with production increase of 5% annually. The production of one ton of cement liberates about one ton of carbon dioxide to the atmosphere. So, one way to produce eco-friendly concrete to reduce the use of Cement is by replacing fly-ash with alkaline liquids.
In this work comparison of compressive strength of Geopolymer concrete with Control concrete. Trial mix proportion the cement is fully replaced by fly-ash with alkaline liquids. Sodium silicate (Na2Sio3) and Sodium hydroxide (Na OH) solution are used as Alkaline liquids in different mix proportions. Concentration of Na OH was kept 8M. Both the liquids were mixed together and alkaline solution was prepared.
In this work split tensile strength and flexural strength were found. The cubes, cylinder and beam are tested at 3, 7, 14 & 28 days. And then the strength Geopolymer concrete compared with control concrete.
