Embodiment 1
[0028] Example 1: The weight percentage of each raw material in slag Portland cement is 5-7% of basalt, 26-28% of Portland cement clinker powder, 6% of dihydrate gypsum, and 61% of granulated blast furnace slag powder.
[0029] Proceed as follows:
[0030] A. Grinding portland cement clinker, dihydrate gypsum and basalt with large roller press and ball mill to produce clinker powder,
[0031] The weight percentage of raw materials is basalt 14.3%, clinker 80%, dihydrate gypsum 2.1%;
[0032] B. Grinding granulated blast furnace slag and dihydrate gypsum with a slag vertical mill to produce fine slag powder. The weight percentage of raw materials is 93.8% of granulated blast furnace slag and 3.9% dihydrate gypsum.
[0033] C. Mix and stir clinker powder with a weight percentage of 35% and fine slag powder with a weight percentage of 65% by a mixing homogenizer to obtain slag portland cement.

[0035] Proceed as follows:
[0036] A. Grinding portland cement clinker, dihydrate gypsum and basalt with large roller press and ball mill to produce clinker powder,
[0037] The weight percentage of raw materials is basalt 17.1%, clinker 77.1%, dihydrate gypsum 2.1%;
[0038] B. Grinding granulated blast furnace slag and dihydrate gypsum with a slag vertical mill to produce fine slag powder. The weight percentage of raw materials is 93.8% of granulated blast furnace slag and 3.9% dihydrate gypsum.
[0039] C. Mix and stir clinker powder with a weight percentage of 35% and fine slag powder with a weight percentage of 65% by a mixing homogenizer to obtain slag portland cement.
Embodiment 3
[0040] Example 3: The percentage by weight of each raw material in the slag Portland cement is: basalt 7.0%, clinker 26.0%, dihydrate gypsum 6.0%, granulated blast furnace slag powder 61.0%.
[0041] Proceed as follows:
[0042] A. Grinding portland cement clinker, dihydrate gypsum and basalt with large roller press and ball mill to produce clinker powder,
[0043] The weight percentage of raw materials is basalt 20.0%, clinker 74.3%, dihydrate gypsum 2.1%;
[0044] B. Grinding granulated blast furnace slag and dihydrate gypsum with a slag vertical mill to produce fine slag powder. The weight percentage of raw materials is 93.8% of granulated blast furnace slag and 3.9% dihydrate gypsum.
[0045] C. Mix and stir clinker powder with a weight percentage of 35% and fine slag powder with a weight percentage of 65% by a mixing homogenizer to obtain slag portland cement.
