Abstract
What the present invention relates to is slag alkali cement and manufacture method thereof, it is characterized in that adopting slag, the high alkali-activator of solid and retardant to make raw material, the common levigate cement that makes after the drying both can be as the convenient use of silicate cement, and its physical and mechanical property is better than other cement with label again, technology investment is few simultaneously, production unit is simple, has made full use of waste residue, turns waste into wealth, improve environment, society and remarkable in economical benefits.
Description
The invention belongs to cement and make the field.
Traditional cement manufacturing method is to adopt two mills, one firing technique, is about to the levigate roasting of starting material and generates grog, and is again that grog and spike is levigate.This technology investment is big, the energy consumption height, and the high offscum in alkali number of metallurgical slag, flyash, chemical industry of the annual discharging in the whole nation can't effectively utilize serious pollution of ecological environment mostly with hundred million tons.Initial stage in the sixties, but Soviet Union scientist begin the lateral reactivity of alkali activated slag is studied, utilize highly basic activated slag lateral reactivity, make it setting and harden, obtain cured body, promptly alleged alkali slag cement and concrete as cement stone.It is actually uses the slag powders with certain fineness, this powder can not as silicate cement alone with water effect setting and harden, when using, the highly basic exciting agent need be mixed with liquid, or with liquid as exciting agent, again with slag powders, gathering materials is mixed into concrete, use, all very inconvenience of transportation.And if solid alkali exciting agent and slag are worn into cement altogether because solid alkali is expensive, so cost height not only, and strength of cement is lower again, so be difficult to apply.
The purpose of this invention is to provide a kind of slag alkali cement and manufacturing process thereof, the slag alkali cement of being produced can equally with ordinary Portland cement use, this technology can reduce investment, cut down the consumption of energy, and the cement early strength height of being produced, later strength increases by a fairly big margin, and has better physical and mechanical property.
Solution of the present invention is, uses slag, the high alkali-activator of solid and retardant to make raw material, and drying to residual water-content is not more than 1%, common grinding to required fineness cement, wherein high-alkali sharp side sends out that alkalinity is in the agent: with equivalent Na
2O weight counts 8～55%, and the proportioning of slag and high alkali-activator is 100: (3～60).
In technique scheme, the proportioning of slag and high alkali-activator is according to following principle the preparation, (SiO in the slag
2) and (Al
2O
3) total amount and the (K in the high alkali-activator
2O) and (Na
2O) ratio of total amount: ((SiO
2)+(Al
2O
3))/((Na
2O)+(K
2=60/1～20/1, and (CaO) in the cement and (SiO O))
2) and (Al
2O
3) ratio of total amount need satisfy ((CaO))/((SiO
2)+(Al
2O
3))=1/2～1/0.5, the content of determining alkali in the high alkali-activator is to guarantee reliable activated slag lateral reactivity.Raw material stoving to residual water-content is not more than 1%, is convenient to grinding on the one hand, the cement that makes on the other hand can not harden before use.With the common grinding of raw material of oven dry, make the raw material can thorough mixing, by test,, make the cement that makes behind the raw material thorough mixing through common grinding, its physical and mechanical property is greatly improved.
Detailed content of the present invention further describes as follows:
Described slag comprises one or more in the non-ferrous metal slags such as blast furnace slag, phosphorus slag, slag, flyash and manganese slag, has made full use of the waste residue of metallurgy industry discharging, turns waste into wealth, and has improved environment again.Described high alkali-activator comprises one or more in saltcake, glauberite, chemical industry alkaline residue, soda ash, sodium sulfate, grog, the unslaked lime etc., like this, adopt on the one hand solid alkali can with the common together grinding of slag, thorough mixing, improve the physical and mechanical property of cement, the cement that makes on the other hand can equally with Portland cement use, and is very convenient, uses the disadvantage of being brought thereby avoided needing that the highly basic exciting agent is made into liquid.Owing to adopt solid alkali to make exciting agent, use highly basic scope to enlarge relatively simultaneously, except the expensive solid-state soda ash of price, alkaloid substance that some other is cheap and alkaline residue all can use, not only reduced cost, but also can turn waste into wealth, comprehensive utilization.Described retardant comprises one or more in gypsum, phosphogypsum, yellow phosphorus slag, sugar, the citric acid etc.
The made cement fineness of the present invention is 4900 holes/cm
2Tail over and be not more than 15%, satisfy requirement of engineering to guarantee the cement that makes.
Slag cement provided by the invention and manufacture method thereof are because the characteristics of its raw material and technology, make the cement that makes in use as ordinary Portland cement, and this cement has the early strength height, and later strength increases big, and physical and mechanical property is better than the characteristics with other cement of label.By the slag alkali cement of this prescription with production method, technology investment is few, and production unit is simple, has saved the energy, and has made full use of waste residue, changes evil for benefit, improves environment, society and remarkable in economical benefits.
Specific examples scheme of the present invention is provided by following examples, and further specifies effect of the present invention.
