Anti-erosion low calcium portland cement and preparation method thereof
The invention discloses anti-erosion low calcium portland cement and a preparation method thereof. The anti-erosion low calcium portland cement comprises clinker and gypsum according to a weight ratio of 96.5: 3.5 to 94.5: 5.5. Minerals of the cement comprises, by weight, 35.03-49.51% of C3S, 25.13-39.00% of C2S, 0.21-8.84% of C3A, 8.2-19.2% of C4AF and 1.71-9.24% of MgO. The cement has good anti-erosion performances, can effectively prevent seawater erosion of concrete engineering, has small dry shrinkage and good anti-cracking ability, improves a service life of oceanographic engineering, and has high early strength. Compared with the existing low-heat portland cement, the anti-erosion low calcium portland cement is conducive to shortening of a concrete work form stripping period and processing progress.
