Description
Technical field
The present invention relates to a kind of carbide slag cement, belong to cement field.
Background technology
Cement is one of important now material of construction, it is the portland cement clinker made after being mixed by mineral raw materials such as Wingdale, fire coal, iron powder and clays, then in grog, adds gypsum make through levigate.Along with the fast development of China's economy, the demand of cement is multiplied.According to incompletely statistics, national cement output in 2012 reaches 21.8 hundred million tons.Meanwhile, the research of special cement is also on the increase.Chinese patent 200710137472.1 discloses a kind of cement intensifier, and it takes full advantage of industrial gaseous waste mixture, reduces cement cost, has saved the mineral products energy, has improved ecotope.Chinese patent 200710055161.0 discloses a kind of antifreezing cement, makes even, the antifreeze degree of cement antifreezing effect high by adding the antifreeze component of cement.Mainly there is following problem in current manufacture of cement: (1) mainly adopts Wingdale as main raw material, cost is higher, and can cause the wasting of resources and environmental pollution, although also some enterprise utilizes the industrial wastes such as carbide slag to produce cement clinker, but mix low, energy consumption is higher; (2) the antifreeze degree of cement is low, can only meet some areas winter construction needs.
Summary of the invention
the technical problem solved:for the above-mentioned deficiency of prior art, the invention provides a kind of carbide slag cement, good freezing protection effect, environmental protection, ultimate compression strength are high, can meet the demand of modern cement.
