Abstract

Sulfate attack in concrete structures is considered to be among the major durability concerns in civil infrastructure systems. Proper modeling techniques can help us understand the durability conditions more readily and accurately. Such an understanding improves the decision making process in every stage of construction and maintenance and will help in better administration of resources. Aspects of cement chemistry, concrete physics, and mechanics are applied to develop a model for predicting sulfate penetration, reaction, damage evolution, and expansion, leading to degradation of cement-based materials exposed to a sulfate solution. The model is refined to address the interaction effects of various parameters using calibration data available from experiments conducted at the National Institutes of Standards and Technology (NIST). Parameters of the model were refined through parametric analysis, consideration of specific boundary conditions, and calibration with experimental data.
