Durability and Microstructure of Sulphur Concrete under Aggressive Environmental Conditions

Abstract

Sulphur concrete has proved to be a suitable construction material due to its ability to develop strength quickly, in a few days, and due to its chemical resistance and ability to withstand aggressive service environments. The long-term durability and microstructural stability under combined environmental actions is, however, a big challenge in predicting. This study suggests an Adaptive Durability and Microstructure Prediction Algorithm (ADMPA) to model the degradation behavior of Sulphur Concrete under corrosive environment. The framework considers the environmental severity as well as sulphur content, exposure period, porosity, and temperature to simulate the durability performance numerically using MATLAB software. According to the proposed model, the durability index, residual strength, mass loss, microstructure integrity and crack resistance factor are 95.8%, 93.4%, 1.9%, 96.2%, and 0.94, respectively, which are better results than conventional prediction models. The suggested computational model is a powerful tool for evaluating the durability of sulphur concrete and its potential use in designing durable infrastructure in corrosive environments.
