Abstract
The present invention discloses a preparation method for low-expansion cement. The preparation method comprises the components in parts by weight: 1-2 parts of ferrous sulfate, 5-10 parts of limestones, 10-12 parts of cement clinker, 8-12 parts of coal ash, 1-3 parts of sodium chloride, 1-2 parts of triethanol amino and 2-3 parts of phenol titanate. The above raw materials obtained by the above ratio are all mixed in a stirring tank and uniformly mixed and crushed, and bagged.
Description
Technical field
The invention belongs to technical field of cement production, relate to a kind of preparation method of low bulk cement.
Background technology
Cement mainly silicate, composite Portland cement common on the market at present, this cement manufacturing process is simple not, and need calcination process, the hearthstone that even needs had forges.And the cement and expanded rate of generation is high, and density is low, is easy to entrained air and foreign matter.
Summary of the invention
For the defect existed in above technology, the invention provides a kind of preparation method of low bulk cement.
For solving the problems of the technologies described above, the preparation method of low bulk cement of the present invention, is characterized in that comprising the following steps:
The first step, gets 1 ~ 2 part, ferrous sulfate, 5 ~ 10 parts, Wingdale, cement clinker 10 ~ 12 parts, 8 ~ 12 parts, flyash, 1 ~ 3 part, sodium-chlor, triethanolamine 1 ~ 2 part, 2 ~ 3 parts, metatitanic acid phenol;
Second step, is mixed in steel basin, Homogeneous phase mixing, smashs to pieces;
3rd step, packs.
