Description
Technical field
The invention belongs to mortar concrete preparing technical field, more particularly to a kind of cement added with flyash is used
Activating flyash agent, the invention further relates to application flyash activator prepare low cost cement.
Background technology
With implementation and national energy-saving emission reduction, the implementation of environmental protection policy, cement industry of the strategy of sustainable development
Resource, the energy, environment the problems such as the principal element that is restricted as it, it is as far as possible to utilize less with Portland clinker more
Industrial residue produces cement, the problem of to be one have environment protection significance and economic value.Flyash is mainly using coal as fuel
Thermal power plant discharge solid waste, flyash is China's discharge capacity and heap high-volume one of maximum industrial residue,
The utilization rate of China is remaining to stack less than 40%, and not only environment is polluted, and also takes up substantial amounts of soil money
Source.Flyash is approximately spherical particle, and the job specification of coagulation scholar can be improved, can improve long-term strength, energy by being acknowledged as having
Reduce the practical value such as cement consumption in concrete.Utilization rate of the flyash in concrete also more and more higher in recent years.However,
If flyash adding proportion is more than 30%, concrete strength is reduced, concrete properties is influenceed, concrete can be caused to receive
Contracting cracking.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of activating flyash agent；The invention solves the problems that the second technology ask
Topic is to provide low cost cement prepared by a kind of application flyash activator.It is intended to flyash is farthest obtained in concrete
To utilization, concrete production cost is reduced, but do not influence concrete properties.
The technical scheme that present invention solution above-mentioned technical problem is taken is as follows：A kind of activating flyash agent, it is characterised in that
Made by the raw material of following weight：20~40 parts of glauber salt, 40~60 parts of alum, 3~6 parts of triethanolamine, Portugal
20~40 parts of 3~6 parts of grape sodium saccharate, 1~2 part of citric acid and silica flour；Above-mentioned raw materials are well mixed and crushed 200 mesh sieves, are made
Obtain activating flyash agent.
Activating flyash agent of the present invention uses raw material sources extensively, and manufacturing process is simple and easy to apply, to equipment, site requirements
It is relatively low, three-waste free discharge, environmental protection；There is good activation function to flyash, prevent concrete surface scum, enhancing construction
The advantages such as performance.
The technical scheme that above-mentioned second technical problem of present invention solution is taken is as follows：It is prepared by one kind application flyash activator
Low cost cement, it is characterised in that by following weight raw material make：40~50 parts of Portland cement, fine coal
6~10 parts of 45~50 parts of ash and activating flyash agent.
Low cost cement prepared by present invention application flyash activator, it is normal according to existing cement, sandstone, water when using
Rule proportioning, simple to performance verification method among traditional material concrete, same to normal concrete, i.e., by national standard or row
Industry standard carries out performance verification.The concrete that the low cost cement prepared using present invention application flyash activator is poured,
Its main performance is as follows：
1st, to concrete early stage intensity effect less, later strength increases obvious；2nd, hydration heat of concrete can be reduced, is reduced
Shrinkage Cracking of Concrete；3rd, concrete water bleeding can be prevented, segregation phenomenon is produced；4th, concrete anticorrosion ability reduction chlorine can be improved
Ion permeates.The cement used in the performance comparison that table 1 is normal concrete with addition activating flyash agent concrete, concrete
Experiment sample uses 42.5 grades of the Portland cement that Gansu Province Pingliang conch cement plant is produced.
