Description

The production method of cement doped active materials
The present invention relates to a kind of production method of Cement Production method, particularly cement doped active materials.
In the prior art, the production method of cement doped active materials is to be main component with Wingdale, clayey raw material, add pyrite slag, hard coal is an auxiliary material, add fluorite again, barite is a mineralizer, and is broken, dry, allocate, be finely ground to raw material, and raw material are added water balling-up calcining, burn till with the Calucium Silicate powder is the Portland clinker of major ingredient, in grog, add active addition and gypsum, levigate making again.See national cement standard GB1344-92.For example, adding the blast furnace slag is " Portland blast " of active addition, and the problem of existence is, the active addition that mixes does not have volcanic ash, and time of coagulation is long, and early strength is low; Anti-freezing property is poor, and weather resistance is bad; Impervious poor, excreting water phenomenon is arranged, be unfavorable for waterproofing work; Moreover the slag quality fluctuation is big, is difficult to control in the production; Slag moisture content is big, needs to increase drying plant in the production, increases the fixed assets input, has strengthened production cost; Slag price height has strengthened production cost.
The present invention is directed to the deficiencies in the prior art, it is good to have proposed a kind of cement performance, the production method of the cement doped active materials that production cost is low.
Task of the present invention is to realize like this, the present invention is a kind of production method of cement doped active materials, be in Portland clinker, mix active addition and gypsum, after fragmentation, the mixing, levigate making, the active addition that mixes Portland clinker are that basalt constitutes, and the per-cent that the basalt that mixes accounts for the cement gross weight is: 5-30%.
Described Cement Production method is being used for the raw material of firing silicate cement clinker, mixes the basalt that accounts for raw material gross weight 6-8% and substitutes the part clayey raw material that accounts for raw material gross weight 6-8%.
The present invention compared with prior art because basalt belongs to natural crystal with SiO 2, Al 2O 3And Fe 2O 3Be main chemical compositions, have volcanic ash, latent hydraulicity is good, and steady quality as the cement that active addition is made, has strong, fast rigid energy early with it, and shorten one hour time of coagulation at least; Anti-folding, ultimate compression strength improve more than 20%.The cement color is dark, and workability is good, no excreting water phenomenon, and water resistance is good; Impervious, frost resistance good, has weather resistance preferably, can be used for the climatope construction more than-5 ℃, wide adaptability; Wear resistance is good, represents with abrasion loss, is not more than 3.5 kilograms/every square metre, can be used for building road; Loss on ignition is not more than 2.5%, and drying shrinkage is little, and contract with dry rate was not more than 0.10% in 28 days; The basalt prices of raw and semifnished materials are cheap, and cement cost per ton is reduced more than 6 yuan at least.
