Influence of Thermal Preconditioning on the Mechanism of External Sulphate Attackr for the two tests. Although the mortar cylinders with thermal pre-conditioning showed stronger degradation earlier according to certain parameters (mass, volume, radius), there was no difference regarding the beginning of the expansion.

An Alternative Method to Evaluate the Sulphate Resistance of Cementitious Binderscimens immersed in sodium sulphate solution (5% Na.SO.) by monitoring the variation in mass and the length change over time. When compared to the current ASTM method, the new method showed a significant acceleration in the rate of expansion with severe visual deterioration observed on the mortar bars in less than one-half the time.

Indikation zum ärztlichen Handelnolume ratio. Quantification of the attack using the depth of alteration in the specimens was studied by X-ray microtomography. The information from the microstructural analysis was used to assess the impact of specimen size, with a view of connecting laboratory specimens to actual structural elements in sulphate-rich environments.
