Durability of high-strength concrete in ammonium sulfate solution

Durability of high-strength concrete in ammonium sulfate solution This paper considers the ammonium sulfate attack of high-strength concrete (grade 100). An accelerated attack consisting in wetting–drying cycles was adopted throughout this study. Compressive strength, mass loss, and length variations were measured before and after sulfate attack. The microstructure was investigated by scanning electron microscopy (SEM). No swelling was observed after six cycles of degradation and the chemical attack was limited to a superficial zone of 5 mm thick. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Cement and Concrete Research Elsevier

Abstract

This paper considers the ammonium sulfate attack of high-strength concrete (grade 100). An accelerated attack consisting in wetting–drying cycles was adopted throughout this study. Compressive strength, mass loss, and length variations were measured before and after sulfate attack. The microstructure was investigated by scanning electron microscopy (SEM). No swelling was observed after six cycles of degradation and the chemical attack was limited to a superficial zone of 5 mm thick.
