Abstract
The invention belongs to the technical field of mortar concrete preparation, and particularly relates to a coal ash activating agent for cement added with coal ash. The coal ash activating agent is prepared from, by weight, 20-40 parts of anhydrous sodium sulphate, 40-60 parts of aluminum potassium sulfate, 3-6 parts of triethanolamine, 3-6 parts of sodium gluconate, 1-2 parts of citric acid and 20-40 parts of silica powder. The raw materials are evenly mixed, smashed and screened through a screen with the mesh number of 200, and the coal ash activating agent is obtained. The invention further relates to the low-cost cement prepared through the coal ash activating agent. The low-cost cement is prepared from, by weight, 40-50 parts of ordinary Portland cement, 45-50 parts of the coal ash and 6-10 parts of the coal ash activating agent. As for concrete poured through the low-cost cement, the early strength of the concrete is hardly affected, and the later strength is obviously increased; hydration heat of the concrete can be reduced, and shrinkage cracking of the concrete can be relieved; the phenomena of bleeding and disintegration of the concrete can be prevented; the corrosion resistance of the concrete can be improved, and chlorine ion penetration can be relieved.
Description
Technical field
The invention belongs to mortar concrete preparing technical field, the particularly activating flyash agent that uses of a kind of cement being added with flyash, the invention still further relates to low cost cement prepared by powder application coal ash activator.
Background technology
Along with the enforcement of the strategy of sustainable development and national energy-saving reduce discharging, the implementation of environmental protection policy, the problem such as resource, the energy, environment of Cement industry becomes its principal element be restricted, use Portland clinker less, utilize industrial residue to produce cement, be a problem with environment protection significance and economic worth more as far as possible.Flyash is mainly the solid waste that the fuel-burning power plant of fuel is discharged with coal, flyash is one of China's quantity discharged and the high-volume maximum industrial residue of heap, in the utilization ratio of China less than 40%, remainingly can only to stack, not only to environment, also occupy a large amount of land resources.Flyash is roughly spheroidal particle, be acknowledged as have can improve coagulation scholar job specification, longterm strength can be improved, the practical value such as cement consumption in concrete can be reduced.The utilization ratio of flyash in concrete is also more and more higher in recent years.But, if flyash adding proportion is more than 30%, then reduce concrete strength, affect concrete properties, can Shrinkage Cracking of Concrete be caused.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of activating flyash agent; The second technical problem that the present invention will solve is to provide low cost cement prepared by a kind of powder application coal ash activator.Be intended to flyash is farthest utilized at concrete, concrete production cost reduced, but does not affect concrete properties.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme taked: a kind of activating flyash agent, it is characterized in that being made by the raw material of following weight: Sodium sulfate anhydrous.min(99) 20 ~ 40 parts, potassium aluminium sulfate 40 ~ 60 parts, trolamine 3 ~ 6 parts, Sunmorl N 60S 3 ~ 6 parts, citric acid 1 ~ 2 part and silica flour 20 ~ 40 parts; Above-mentioned raw materials is mixed and pulverized 200 mesh sieves, obtained activating flyash agent.
Activating flyash raw material sources that agent uses of the present invention are extensive, and manufacturing process is simple, lower to equipment, site requirements, three-waste free discharge, environmental protection; There is good mobilizing function to flyash, prevent concrete surface scum, strengthen the advantages such as workability.
It is as follows that the present invention solves the technical scheme that above-mentioned second technical problem takes: low cost cement prepared by a kind of powder application coal ash activator, is characterized in that being made by the raw material of following weight: ordinary Portland cement 40 ~ 50 parts, 45 ~ 50 parts, flyash and activating flyash agent 6 ~ 10 parts.
Low cost cement prepared by powder application coal ash activator of the present invention, according to existing cement, sandstone, water conventional proportions during use, be applied in the middle of traditional material concrete, simple to performance verification method, same normal concrete, namely carries out performance verification by GB or industry standard.The concrete that the low cost cement using powder application coal ash activator of the present invention to prepare is built, its salient features is as follows:
1, little to concrete intensity effect in early stage, later strength increases obviously; 2, can hydration heat of concrete be reduced, reduce Shrinkage Cracking of Concrete; 3, can prevent concrete water bleeding, segregation phenomenon produces; 4, concrete anticorrosion ability can be improved and reduce chloride permeability.Table 1 is normal concrete and the concrete performance comparison of interpolation activating flyash agent, the ordinary Portland cement 42.5 grades that the cement experiment sample used in concrete adopts conch cement mill, Pingliang, Gansu Province to produce.
