Abstract
The invention discloses green environmental-protection cement, which is characterized by comprising, by weight percentage: 45-65% of industrial garbage, 25-30% of desulfurized gypsum, ferrous sulphate no more than 7.5%, sodium sulfate no more than 5.5%, 0.5-1.5% of alum, 1-3% of potassium nitrate, and magnesium oxide no more than 7.5%. The cement has advantages that industrial garbage is utilized, and waste is changed into valuables. The cement is green and eco-friendly, and is low in cost.
Description
Technical field
The invention belongs to technical field of cement production, relate to a kind of green environment cement.
Background technology
Conventional cement manufacturing process adopts silicate to be prepared as starting material, and its raw-material drawing materials exists problem such as the work wasting of resources and environmental pollution etc.And along with the quickening of Process of Urbanization Construction, the demand of social development to cement is increasing, further increases the consumption of cement manufacture, increased the weight of the burden of manufacture of cement.Meanwhile, other corresponding steel produces, generating, and building manufacture waits the manufacture of industrial refuse also day by day serious.If one can be had to gather materials on the spot, utilize these trade wastes will bring immeasurable resources conservation to society, the benefits such as environment protection to the product manufacturing cement.
Summary of the invention
For solving the above-mentioned problems in the prior art, the object of this invention is to provide a kind of green environment cement of turning waste into wealth of drawing materials conveniently, utilizing industrial refuse to be prepared.
For this reason, green environment cement of the present invention consists of the following composition, industrial refuse: 45 ~ 65%, desulfurated plaster 25 ~ 30%, ferrous sulfate≤7.5%, sodium sulfate≤5.5%, alum 0.5 ~ 1.5%, saltpetre 1 ~ 3%, magnesium oxide≤7.5%.
The mixture of described industrial refuse to be industrial refuse be flyash, wet fly-ash, coal gangue, Wingdale.
Advantage of the present invention has: utilize the compositions such as flyash, wet fly-ash, coal gangue, Wingdale to be prepared cement.And these materials all belong to steel refining, send out the common industrial refuse of point, building materials industry, make the present invention have the value of environmental protection thus, while manufacturing cement, consume the refuse pollution that other industry is brought.Meanwhile, because draw materials conveniently, make the present invention with low cost, be easy to market and popularize.
Embodiment
