Field Performance of Portland Limestone Cement Concretes Exposed to Cold-Temperature Sulphate Solutin varying limestone contents. The addition of fly ash or silica fume to Portland limestone cement produced concretes with better sulphate resistance than Type MS (moderate sulphate) cement concretes and mirrored the performance of ordinary Portland cement with fly ash and silica fume.作者: 粘連 時(shí)間: 2025-3-23 01:10 作者: thrombosis 時(shí)間: 2025-3-23 02:10 作者: TERRA 時(shí)間: 2025-3-23 08:54
Influence of Temperature and Aggressive Solutions in the Formation of Thaumasite and Ettringite in Swith time. The mortars with alkali reactive aggregates (opal plus quartz) show alteration under all conditions with variable damage. On the other hand, the expansion and the formation of thaumasite or ettringite is favored by low temperature and solution combination.作者: 擦掉 時(shí)間: 2025-3-23 11:22
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.作者: Adenocarcinoma 時(shí)間: 2025-3-23 15:22 作者: paroxysm 時(shí)間: 2025-3-23 20:04 作者: Muffle 時(shí)間: 2025-3-23 22:19 作者: 性冷淡 時(shí)間: 2025-3-24 06:00 作者: sulcus 時(shí)間: 2025-3-24 07:47
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.作者: pulmonary 時(shí)間: 2025-3-24 12:24

One way to achieve that is to dry the material at 60?°C then to saturate it with a sulphate solution before the test.

With a modified test method, significantly better test results could be achieved for cements with known high and low sulphate resistance.
