ABSTRACT

The mortar samples exposed to Na2SO4 solution showed much more expansion than the samples exposed to Na2SO4 + NaHCO3 solutions. The samples showed after the interaction with

1 INTRODUCTION

Chemical degradation of cementitious materials is a serious threat to the durability and performance of concrete structures. Recent advances in modeling have enabled adequate description of the changes associated with sulfate ingress either using simple “0-dimensional” models or 1-dimensional reactive transport models, which gave comparable results and were able to reproduce the changes observed in experiments.
