Abstract
The invention relates to the technical field of cements, and especially relates to a cement assistant. The cement assistant comprises, by mass, 40-60 parts of calcium sulfate, 100-120 parts of limestone, 10-15 parts of a stabilizer and 12-15 parts of a retarder, and preferably comprises, by mass, 40 parts of calcium sulfate, 120 parts of limestone, 10 parts of epoxy ester, 15 parts of citric acid and 5 parts of fly ash. The stabilizer well improves the integral stability of the cement assistant prepared through adopting the above formula; the retarder well plays a role in retardation; and an activator well improves the activity of the cement assistant.
Description
Technical field
The present invention relates to cement technology field, particularly a kind of cement adjuvant.
Background technology
In the calcination process of manufacture of cement, for improving burnability of raw material, complete the forming process of cement clinker faster, particularly when lime kilning saturation factor is high or raw material containing alkali and quartz sand in raw material time, prior art needs in calcination process, to add the auxiliary agents such as natural dihydrate gypsum, Calcium Fluoride (Fluorspan), phosphogypsum as mineralizer usually.
Chinese invention patent application CN1594174A discloses a kind of method of industrial waste production cement adjuvant, the method with the waste material of calcium sulfate for raw material, this waste material is the pulpous state waste material to producing in the process processed wastewater produced in titanium white production, this waste material is carried out press filtration, remove portion of water and become bulk, then drying treatment is carried out to this lumpy material, dried material made bulk or is crushed to particulate state or powdery, being cement adjuvant finished product.Although present invention utilizes industrial waste, the performances such as the activity of this cement adjuvant are good not.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of cement adjuvant with delayed coagulation.
For solving above-mentioned technical problem, a kind of cement adjuvant of the present invention comprises according to mass fraction meter: calcium sulfate 40-60 part, Wingdale 100-120 part, stablizer 10-15 part, retardant 12-15 part.
Further, described stablizer is the one in epoxy ester, N.F,USP MANNITOL, phosphorous acid ester.
Further, described retardant is the one in citric acid, glycerol, boric acid.
Further, promoting agent 5-10 part is also comprised.
Further, described promoting agent is the one in zeolite, silica flour, flyash.
Further, 40 parts, calcium sulfate, 120 parts, Wingdale, epoxy ester 10 parts, citric acid 15 parts, 5 parts, flyash.
After adopting above-mentioned formula, cement adjuvant of the present invention well improves the stability of cement adjuvant entirety by stablizer; In addition, the effect of slow setting is well played by retardant; Promoting agent can well improve the activity of cement adjuvant.
