Abstract
The invention discloses composite cement made from basalt. The composite cement is prepared from 30-60 parts by weight of clinker, 20-40 parts by weight of slag, 3-20 parts by weight of fly ash, 3-20 parts by weight of basalt and 3-7 parts of gypsum. The fluidity of cement is improved with basalt replacing limestone, during preparation of concrete, the amount of water can be reduced, the compactness of the cement can be improved due to adoption of the basalt, and accordingly, by comparison with cement prepared from limestone, the three-day strength of the composite cement is greatly improved, and the overall performance of the cement can be better.
Description
Technical field
The present invention relates to cement field, particularly relate to a kind of use basalt as the complex cement of material and
Preparation method.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material, becomes slurry after the stirring that adds water, can be the hardest
Change or preferably harden in water, and can be the most cemented together for the material such as sand, stone.Cement is usual
With lime stone as primary raw material, it is equipped with slag, flyash, gypsum etc. by proportioning.Due to the thin slag powders of height and
The feature that early strength that flyash has is low, if 3 days pressure resistances when producing portland slag cement with it
Spend on the low side, the most only 11.2Mpa, although reached the national standard requirement of 32.5 grades 10.0pa, but
Quality risk is very big, can only take to increase the measure of limestone content, cause manufacture of cement cost increase, give
Enterprise causes bigger economic loss.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of use basalt as the complex cement of material and
Preparation method, it is possible to increase 3 days compression strength and rupture strength, reduces manufacture of cement cost.
To achieve these goals, the present invention provides following technical scheme:
A kind of use basalt as the complex cement of material, including the raw material of following parts by weight:

Preferably, one or both during described gypsum is dihydrate gypsum, desulfurated plaster or ardealite.
Present invention also offers the above-mentioned use basalt preparation method as the complex cement of material, its feature
It is, comprises the following steps:
A) grog, slag, flyash, basalt and gypsum are dried at 50～80 DEG C, take out, cool down,
Standby；
B) grog, slag, flyash, basalt and gypsum that step a) takes out are put into grinder to carry out
Grind, obtain pulverulent mixture；
B) pulverulent mixture obtained by step b) calcines 30～60min at 700～1000 DEG C, cooling.
Preferably, after step a) is dried, moisture in grog, slag, flyash, basalt and gypsum
Content is not higher than 2wt%.
Preferably, after grinding, the fineness of described pulverulent mixture is 0.8～1.2.
From technique scheme it can be seen that the present invention provide use basalt as the complex cement of material,
Improving the mobility of cement by using basalt to substitute lime stone, it is when preparing concrete, it is possible to reduce
Watering quantity, and basalt can improve the packing of cement, and therefore it is compared to lime stone, and within 3 days, intensity obtains
To improving significantly so that the overall performance of cement is more preferable.
