Title: Influence of Concentration of Ammonium Nitrate Solutions on Concrete
Author(s): U. Schneider and S.-W. Chen
Publication: Special Publication
Appears on pages(s): 439-458
Keywords: ammonium nitrate; bending strength; compressive strength; concrete
Abstract:The behavior of ordinary concrete and high strength concrete under chemical attack was studied over a period of more than 5 years. The concrete specimens were immersed in a variety of chemical solutions including 10%, 5%, 1% and 0.1% ammonium nitrate solutions and simultaneously subjected to different flexural loads with load levels of 0%, 30%, 40% and 50% of their initial flexural strengths. The strength and mass changes of the concrete specimens, and the penetration depths of the attacking ammonium nitrate ions into the specimens were measured. The influence of concentration level of the solution on the bending strengths of the concretes was studied and is dis- cussed on the basis of experimental observations
