Abstract
The present invention relates to composite excitant for cement, which solves the problem that the existing excitant can only enhance the early strength of cement without enhancing later strength. The composite excitant for cement is composed of the following materials having the proportion by weight of 45 to 50% of aluminium sulfate residues, 15 to 20 % of industrial salt, 15 to 20% of lime for construction, 10 to 14% of sodium sulphate and 1 to 1.5% of calcium lignosulphonate. The composite excitant for cement can be used for cement production in use to enhance strength, particularly later strength, shorten coagulation time and improve stability. The excitant can be used for reducing 10% of cement clicker under the condition of the same cement strength, and the cost of per ton cement is reduced by 10 yuan.
Description
Technical field
The invention belongs to technical field with industrial residue producing cement.
Background technology
Along with the building materials development of science and technology, flyash, liquid slag, boiling furnace slag, coal gangue, slags etc. have been widely used in the manufacture of cement, in order to excite the activity of waste residues such as flyash, numerous scientific and technical personnel have done a large amount of research to exciting agent, and some patent documentations report arranged, as CN87105441,200510043962.6 etc., but still there is weak point in actual applications in these researchs, such as 200510043962.6 cement rapid hardening excitants, it only solves the early strong problem of cement, do not strengthen for later strength, even retraction can take place, and can not shorten cement setting time, improve soundness, and, complex process, cost is higher.
Summary of the invention
The objective of the invention is to propose a kind ofly can improve strength of cement, particularly later strength the cement composite exciting agent that shortens time of coagulation.
Cement composite exciting agent of the present invention comprises following raw materials by weight percent:
Aluminium sulfate slag 40--------55%
Industrial salt 14.5------20%
Building lime 20--------24%
Sodium sulfate 0--------14.5%.
In order to reduce the moisture content in the material, can in such scheme, increase the wooden calcium of following weight percent
0.5------1.5％。
Aluminium sulfate slag is the residuum after alumina and sulfuric acid reaction extract Tai-Ace S 150, residue just, and the mud of water content more than 50%, its main component is SiO
2About 70%, Al
2O
316%, CaO, Fe
2O
3, MgO accounts for 3%, SO
30.05%, loss on ignition 9.6%.Building lime is a lime, and the content of CaO+MgO is 60---90%.
The preparation of this cement composite exciting agent is to adopt artificial mix method, just can mix in the manufacture of cement in the ratio of 1-3% in three, four days after stirring.
Mix cement mortar of the present invention in manufacture of cement, can improve cement intensity, improve stability, particular case sees the following form.
The cement physical properties contrast

As can be seen from the above table, after mixing 3% cement composite exciting agent of the present invention, the early strength and the later strength of cement all are significantly improved, under the constant situation of cement clinker amount, can improve 28 days later stages intensity 8----12MPa, cement setting time shortens 30----60 minute, and has improved soundness.Under the identical condition of strength of cement, can reduce cement clinker about 10%, can improve blended material incorporation 15---25% in cement, deduct the cost of this exciting agent and blended material, cement per ton can reduce cost about 10 yuan.In a word, use this exciting agent can improve cement quality, reduce cost, and its raw material is easy to get, preparation is simple, and with low cost, effect is remarkable.
