Changes in the thermal expansion coefficient of concrete due to exposure to aggressive chemical environment

An analysis of the impact of long-term sulphate examination conditions on the thermal expansion of ordinary cement concrete made with the use of various limestone aggregates is presented in the paper. The article contains the results of selected chemical and temperature laboratory testing. This issue is of significant value for the description of cement concrete durability under aggressive conditions in a wide range of temperatures. The experimental results can usefully be applied to predicting the sustainability of ordinary cement concrete as well as its joints working under defined aggressive conditions
