Performance of Geopolymer Concrete at Elevated Temperature and Against Aggressive Chemical Environment

Abstract

The present paper reports result of an experimental program conducted to study the behavior of geopolymer concrete at elevated temperature on the basis of physical appearance, weight loss and residual compressive strength test. The geopolymer concrete cubes of 150×150×150 mm were cast. Three cubes were tested for compressive strength at the age of 7 days and 28 days by universal testing machine. Then the specimen were subjected to the elevated temperature 200oc, 400oc, 600oc, 800oc and 1000oc in an electric air heated muffle and after cooling were tested for the compressive strength. Six cubes were immersed in each solution of sodium sulphate, sulfuric acid, and sodium chloride for 30 days and 60 days. The test reveal the properties of geopolymer concrete and its applicability at elevated temperature and against aggressive environment such as acid attack, sulphate attack and chloride attack.
