Abstract
The cement strength excitant includes composite surfactant comprising triethanolamine and triisopropanolamine and cement slurry decontamiating embryo, which are crushed and mixed through stirring before packing as product. It is added into cement clinker during pulverization and can excite both the early strength and the later strength after 28 days of cement, increase the yield of cement grinding machine, reduce its power consumption, and improve the stability and mixability of cement.
Description
The present invention relates to material of construction cement, particularly a kind of cement strength excitant that adds in the cement.
Along with progress of science and technology, shaft kiln cement plant is by a series of Measures of technical, the aspect has obtained than great achievement improving cement output, quality and cut down the consumption of energy etc., particularly on the homogenizing of raw material, fuel, on cutting down the consumption of energy, the employing low grade coal carried out bigger research, strengthening also having spent great strength aspect operation, tighten management, the reforming equipment simultaneously, but research is less aspect excited cement intensity.
Existing No. 425 cement, because clinker from vertical kiln intensity majority about No. 525, is difficult to produce cement No. 525, and owing to be subjected to the restriction of grog label, blended material adds less, causes cost higher thus.
The purpose of this invention is to provide a kind of new cement strength excitant, it adds when the pulverizing cement grog, has both excited the early strength of cement, has also excited 28 days later strength of cement.
Technical solution of the present invention is as follows:
A kind of cement strength excitant, it comprises complexed surfactant and cement paste embryos, wherein complexed surfactant is made up of trolamine and tri-isopropanolamine; Described complexed surfactant and cement paste embryos are stirred after crushed, again packaging final prod.
Existing No. 425 silicate cements, ordinary Portland cement, slag cement, pulverized fuel ash cement and volcano matter cement after adding 2%～8% cement strength excitant of the present invention, can make above-mentioned cement mark be strengthened to No. 525～No. 625; Also can mix blended material 10%～30% more.
After adopting cement strength excitant, cement mill output about 10% can be improved, cement power consumption of the mill about 10% can be saved; Also can help to clear up the part free calcium oxide, improve soundness, workability.
Below in conjunction with embodiment the present invention is elaborated.
A kind of cement strength excitant comprises complexed surfactant and cement paste embryos, and wherein the proportioning of complexed surfactant is 10%～16%, and the proportioning of cement paste embryos is 84%～90%.Complexed surfactant is made up of three ethanol and tri-isopropanolamine.
The consumption that complexed surfactant accounts in the cement is 0.03%～1%, and the best is 0.3%～0.5%.Can in cement grinding mill, play the grinding aid effect after adopting complexed surfactant, improve cement mill output.Tensio-active agent can make tiny cement granules have good dispersiveness and static resistance.When cement and water generation hydration reaction, water is fully contacted with cement granules, have good humidification and osmosis, can improve cement and concrete various mechanical property greatly, and to the effect of reinforcing bar non-corroding.
The consumption that the cement paste embryos accounts in the cement is 2%～4%, is at least 2%.Cement is in hydration process, and hydrated product constantly generates calcium silicate hydrate gel and the final cement stone with certain intensity that forms.Along with going deep into of hydration process, crystal constantly increases, and cement stone also just has more and more higher intensity.And the brilliant base of special cement can play and promotes hydrated cementitious, promotes the effect that crystal generates, and makes that cement and concrete are strengthened in early days, the purpose of late-enhancement thereby reach.
The brilliant base of complexed surfactant and cement paste is stirred after crushed, and packaging final prod can add in the pulverizing cement grog and go again.
Also can mix rare earth ore in cement strength excitant of the present invention, the consumption that rare earth ore accounts in the cement is 0.3%～2%.
Also can mix zeolite in cement strength excitant of the present invention, the consumption that zeolite accounts in the cement is 0.5%～3%.
Also can mix the Attapulgite ore in cement strength excitant of the present invention, the consumption that the Attapulgite ore accounts in the cement is 0.3%～1%.
Zeolite and Attapulgite ore are the mineral substance with porous frame shape structure, and its internal surface area is huge, has good adsorption, ion exchangeable and catalytic.They are active mixed materials of cement, can improve soundness, also can improve the tension and the ultimate compression strength of cement.
The rare earth ore, zeolite and the Attapulgite ore that mix in the cement strength excitant need to be stirred after crushed, mix.
Cement strength excitant is added in No. 425 ordinary portland cements, its folding strength 3 days be 4.8,28 days be 6.6; Its ultimate compression strength 3 days be 21.6,28 days be 44.2.
In No. 425 ordinary portland cements, add 3% cement strength excitant, its folding strength 3 days be 5.1,28 days be 7.2; Its ultimate compression strength 3 days be 28.5,28 days be 55.8.Strength of cement is equivalent to No. 525.
In No. 425 ordinary portland cements, add 5% cement strength excitant, its folding strength 3 days be 5.5,28 days be 8.1; Its ultimate compression strength 3 days be 32.8,28 days be 65.2.Strength of cement is equivalent to No. 625.
