One part silica fume replacing 3 ∼ 4 cement means the total binder weight is reduced. Because the total heat is a function of the total binder weight silica fume cement can effectively be used as low heat cement. AS 3972 requires that cement producers specify the heat of hydration of their cements.
Low-heat Portland Cement Products Business
· Features. This cement features extremely low heat of hydration. It offers excellent long-term strength. This cement has a high percentage of belite (C 2 S) at approximately 60 .
Low Heat CementStructural Guide
· As indicated in the above table of ASTM C186 the average heat generated by the Type IV cement is low when compared with other types of portland cement. Why we need low Heat Cement The rise of the heat of hydration in the concrete leads to cracking of concrete. We need to limit the temperature rise to avoid the craking.
