Abstract
A kind of concrete early strength agent and preparation method thereof, relate to industrial chemicals technical field, carried out after rational proportioning formula carries out hybrid process, preparing after drying granulation by aluminum sulfate, gypsum, sulfate, sodium carbonate, slag powders, triethanolamine, potassium hydroxide, flyash, ammonium chloride, calcium silicates and water.The invention has the beneficial effects as follows: the present invention prepares convenient and simple, environment friendly and pollution-free, raw material is easy to get, and equipment investment is few, it is simple to operation, and the concrete early strength agent using effect of preparation is good, and ability of derusting is strong, and no side effects is safe and reliable.
Description
Technical field
The present invention relates to industrial chemicals technical field, be specifically related to a kind of concrete early strength agent and preparation side thereof
Method.
Background technology
Concrete early strength agent is one of concrete admixture, and concrete early strength agent refers to improve concrete early
Phase intensity, and the additive that later strength is not made significant difference.The Main Function of early strength agent is to accelerate
Hydrated cementitious speed, promotes the development of early strength on coagulation；Both there is early powerful, had again certain
The additive of water reducing and strength increasing function is referred to as early strength water-reducing agent, but metal-derusting present on current market produces
Product are a feast for the eyes, but, what a kind of concrete early strength agent can be real plays obvious effect,
But also corresponding toxicity can be there is, affect health.
Summary of the invention
The technical problem to be solved is to provide a kind of intensity high, condenses fast concrete the strongest
Agent and preparation method thereof.
The technical problem to be solved realizes by the following technical solutions:
A kind of concrete early strength agent, it is characterised in that: include the raw material composition of following weight portion,

Acid calcium 8 parts, deionized water 35 parts；
It is another object of the present invention to prepare the method for concrete early strength agent in the present invention, it is characterised in that:
Comprise the following steps:
A, select a reactor, in the deionized water of half adds reactor in raw material, then by raw material
In aluminum sulfate, sulfate, sodium carbonate, triethanolamine and potassium hydroxide be added thereto, add unlatching stirring,
It is heated to 20-30 DEG C so that it is after being completely dissolved, pours out；
B, select an agitator tank, the residue deionized water in raw material is added thereto, the most again by raw material
Ammonium chloride and calcium silicates, stirring is until after ammonium chloride and calcium silicates all dissolve, obtaining solution A, standby；
C, the solution poured out in material A and step a is sufficiently mixed after, stir, then by former
In material, gypsum, slag powders and flyash are ground into foam, are added in agitator tank, after being then sufficiently stirred for,
Carry out drying granulation, pack after filtration.
The invention has the beneficial effects as follows: the present invention prepares convenient and simple, environment friendly and pollution-free, raw material is easy to get,
Equipment investment is few, it is simple to operation, and the concrete early strength agent using effect of preparation is good, and using effect is obvious,
No side effects, safe and reliable.
