Abstract
Patent of the present invention is the prescription with mixed cement material from phosphorus slag, belong to the Application in Chemical Engineering technical field, the technical issues that need to address are to obtain optimum mix, setting and harden speed and early stage intensity etc., the major technique feature is with cement clinker, the phosphorus ore slag, admixture or compound additive, prepare burden according to a certain ratio, through mixing, ball milling, packing, dispatch from the factory, owing to contain a spot of fluorine and phosphorus in the phosphorus slag, do not handle as long-term stacking, not only cause a large amount of occupied grounds, but also pollute the environment, utilize cheap phosphorus slag to make cement mixture, turn waste into wealth, reduced the Cement Production cost, be applicable to construction work.
Description
Patent of the present invention belongs to the Application in Chemical Engineering technical field.
A kind of waste residue that the phosphorus ore slag discharges when being electric heating process production yellow phosphorus is whenever produced one ton of yellow phosphorus, discharges 8～10 tons of phosphorus ore slags approximately.Owing to contain a spot of fluorine and phosphorus in the phosphorus slag, do not handle as long-term stacking, not only cause a large amount of occupied grounds, but also pollute the environment.The phosphorus ore slag is compared with the granulated blast-furnace slag, and its main drawback is that setting and harden is slow, drought period intensity low.By prior art,, can not satisfy user's requirement if the volume of phosphorus slag in cement greater than 20%, just might make cement setting time reach more than 10 hours.Just because of these problems, so phosphorus slag can only be used for cement mixture in a small amount at present, general volume is all less than 20%.
The purpose of patent of the present invention is to obtain optimum mix, setting and harden speed and early stage intensity etc. through experiment and practice, and utilizes cheap phosphorus slag to make cement mixture, turns waste into wealth, and reduces the cost of manufacture of cement, for the development of material of construction is made contributions.
The content of patent of the present invention: the prescription with mixed cement material from phosphorus slag is as follows: cement clinker 40～80%, phosphorus ore slag 20～60%, admixture 2～7%, with starting material by the preparation of as above proportioning after, mix, dropping in the grinding machine through being ground to fineness is that 4900 hole sizers tail over less than 10%.Wherein admixture is sodium sulfate (saltcake), and it both can be industrial goods, can be industry byproduct also, or is the waste residue etc. of major ingredient with sodium sulfate, and the effect of admixture mainly is to improve early strength and adjust time of coagulation.According to the difference of raw material quality and the size of phosphorus slag volume, can make 325 respectively
#, 425
#, 525
#Cement.Generalized case, the grog label is greater than 450
#, volume 55～65%, phosphorus slag volume 35～45%, anhydrous sodium sulphate 3～5%, the control cement fineness is 5～7%, every index of cement all satisfies GB 425
#The performance requriements of Portland blast.By the cement initial set of being produced of as above filling a prescription is 45 minutes to 2 hours, and final set is 2 hours to 6 hours, and therefore, its time of coagulation is quite desirable.The intensity in each length of time all meets or exceeds the requirement of GB like product, and the later strength of this cement still has growth by a relatively large margin.As will further improving early strength, accelerate cement setting, can adopt compound additive, compound additive is by sodium sulfate and yellow soda ash (being soda ash) preparation, or by sodium sulfate and water glass (being water glass) preparation, the proportioning of compound additive is that sodium sulfate equals 10 than soda ash (or water glass): (0.1～5).The volume of compound additive and production control parameter are identical when singly mixing sodium sulfate.
The advantage of patent of the present invention or positively effect: 1. utilize waste residue; 2. reduce the manufacture of cement cost, different according to the practical situation of various places, general cement per ton can reduce production costs 10～20 yuan; 3. the volume owing to phosphorus slag is bigger, so, under the situation that does not increase any investment, can increase cement output 10～40%.
Description of drawings: the Recipe of patent of the present invention according to proportion ingredient, through mixing, ball milling, finished product packing, dispatch from the factory, promptly obtains satisfied economic benefit and social benefit with cement clinker, phosphorus ore slag, admixture as shown in Figure 1.
Realize the best way of patent of the present invention: for example (label is greater than 450 with grog
#) 60%, phosphorus ore slag 40%, admixture sodium sulfate (industrial goods) 3%, accurate measurement after mixing, drops in the ball mill, the control cement fineness is 5～7%, can produce 425
#Slag cement.
