Reuse of waste sulfur as a binding agent in concrete

Abstract

Mainly due to the strict global environmental regulations regarding the oil and gas refining processes, which limit the maximum quantity of sulfur in combustibles, the availability of waste sulfur has been considerably growing during the last decades and it is evident that there will be a continuous abundant supply of waste sulfur in the future. Finding new ways for waste sulfur consumption thus becomes very important. In this research, possibility of using waste sulfur as a binding agent in concrete was analyzed and the properties of the obtained sulfur polymer concrete in aggressive environments were examined using destructive and non-destructive testing methods. Compressive strength changes were insignificant. Ultrasonic measurements indicated significant homogeneity changes and slight internal degradation. Based on the obtained results, the material with satisfying quality for possible application in corrosive environment was produced.
