Background technique
Concrete be most widely used in modern society, a kind of maximum construction material of usage amount, China is in the world
Using the maximum country of concrete material, as country is for the huge investment of foundation construction field and for the urgent of urbanization
The situation for growth of walking unhurriedly is presented in the usage amount short time of demand, China's concrete and associated materials, concrete passes through concrete
The hydration reaction solidification carried out between material is to have stronger compression strength, however, due to existing between concrete material
Barrier is reacted, the hydration reaction of common concrete material is only capable of completion 70~80%, moreover, the hydration reaction class of concrete material
Like the process of crystal structure, the product that common concrete material only has about 80% after hydration reaction is formd with structural strength
Concrete, there are segmental defects for remaining reaction product, and the compression strength of concrete entirety is caused not can be further improved.
In order to further increase the performance of concrete, generallys use add potent dose, potent dose thereto in the prior art
Main function it is main there are two, first is that increase concrete material dispersibility so that can between the particle of concrete material
Fully disperse, prevent it from reuniting together, and then accelerate the hydration process of cement, reduces the usage amount of cement in concrete,
Second is that increasing other concrete additives such as water-reducing agent etc. for the adsorption capacity of concrete material, enhance its using effect.

Polyoxyethylene ether, sodium lignin sulfonate, filler material are added in reactor, are stirred 1~2 hour, are obtained at a temperature of 50~80 DEG C
To mixture A；And then stir triethanolamine, modified starch in water 0.5~1 hour, obtain mixture B；Finally to mixing
Mixture B is poured into object A, after being mixed 1 hour, obtains Concrete strength agent mother liquor.The technical solution can be applied to coagulation
Soil additive technical field can be realized and be effectively improved defect present in concrete in the prior art, can be improved concrete
Comprehensive performance.
In the prior art, in potent dose of raw material usually include water-reducing agent, and in water-reducing agent polycarboxylate water-reducer performance
Preferably, but its higher cost, and preparation process is complicated.Compared to polycarboxylic acids dehydragent, ligninsulfonate water-reducing agent cost
Low, preparation process is simple, but its water-reducing rate generally only has 8~10%, and use scope is relatively narrow.
