Embodiment 1
[0026] When formulating anti-scour low-heat Portland cement, the weight percentage of each component contained in the firstly prepared anti-scour mixture is:
[0027] Active Microsilica 84%
[0028] Ultrafine low calcium fly ash 15%
[0029] Superplasticizer 1%
[0030] After mixing the anti-scouring mixture evenly, mix it with finely ground low-heat Portland cement clinker and gypsum. The weight ratio is:
[0031] Low heat portland cement clinker 85%
[0032] Anti-abrasion compound 13%
[0033] Gypsum 2%
[0034] Among them, the average particle size of the low-heat Portland cement clinker is 0.1-0.3 μm;
[0035] Then, the three components are mixed uniformly through a cement mill, and the fineness is controlled to 12%, that is, the anti-scouring low-heat Portland cement is obtained.
Embodiment 2
[0037] When formulating anti-scour low-heat Portland cement, the weight percentage of each component contained in the firstly prepared anti-scour mixture is:
[0038] Active Microsilica 90%
[0039] Ultrafine low calcium fly ash 8.8%
[0040] Superplasticizer 1.2%
[0041] After mixing the anti-scouring mixture evenly, mix it with finely ground low-heat Portland cement clinker and gypsum. The weight ratio is:
[0042] Low heat portland cement clinker 85%
[0043] Anti-abrasion compound 13%
[0044] Gypsum 2%
[0045] Among them, the average particle size of the low-heat Portland cement clinker is 0.1-0.3 μm;
[0046] Then the components are mixed uniformly through a cement mill, and the fineness is controlled to be 12%, so as to obtain the anti-erosion low-heat portland cement.
Embodiment 3
[0048] When formulating anti-scour low-heat Portland cement, the weight percentage of each component contained in the firstly prepared anti-scour mixture is:
[0049] Active Microsilica 90%
[0050] Ultrafine low calcium fly ash 8.8%
[0051] Superplasticizer 1.2%
[0052] After mixing the anti-scouring mixture evenly, mix it with finely ground low-heat Portland cement clinker and gypsum. The weight ratio is:
[0053] Low heat portland cement clinker 90%
[0054] Anti-abrasion compound 8%
[0055] Gypsum 2%
[0056] Among them, the average particle size of the low-heat Portland cement clinker is 0.1-0.3 μm;
[0057] Then the components are mixed uniformly through a cement mill, and the fineness is controlled to be 12%, so as to obtain the anti-erosion low-heat portland cement.
