Abstract
The present invention proposes a kind of early strength agent for cement concrete, and its composition is counted as follows in parts by weight：15 25 parts of calcium chloride, 35 parts of methyl diethanol, 10 15 parts of sodium metasilicate pentahydrate, 36 parts of Fatty acid methyl ester sodium sulfonate, 12 15 parts of ethylene glycol, 13 parts of methyl acrylate, 12 18 parts of water, shorten initial set and the final setting time of concrete, improve efficiency of construction.
Description
Technical field
The present invention relates to a kind of early strength agent, and in particular to a kind of early strength agent for cement concrete.
Background technology
Concrete early strength agent refers to the additive that can improve early age strength of concrete, more in the winter time construction or rush repair
Shi Caiyong, at present the more conventional concrete early strength agent in China mainly have villaumite system, sulfate system, carbonate system, organic matter
System, mineral substance and complex accelerator, the most frequently used several classes mainly include：(1) chloride salt early strength agent：Mainly there are calcium chloride, chlorination
Sodium, potassium chloride, amine oxide, iron oxide, aluminum oxide etc., chloride salt early strength agent have good early strength function, wherein calcium chloride morning
Potent fruit is good and cost is low, most widely used.(2) Sulfates early strength agent：Mainly there are sodium sulphate (i.e. glauber salt), thiosulfuric acid
Sodium, calcium sulfate, aluminum sulfate, alum etc..Wherein sodium sulphate is using more.(3) organic species early strength agent：Organic amine is early
Strong agent mainly has triethanolamine (abbreviation TEA), triisopropanolamine (abbreviation TP), diethanol amine etc., and wherein early strong effect is with three second
Hydramine is preferred.A few class early strength agent singly can be mixed or compound more than in engineering.Villaumite system early strength agent has obvious action of rust to reinforcing bar,
Therefore the early strength agent application of chloride system is seldom.Sulfate system early strength agent is also due to cause concrete " scum ", and alkali be present
Aggregate reaction endangers risk, and its application is also very restricted.Some other species early strength agent, or there is early strong effect
It is bad, or influence later strength, or raw material sources be present, the problems such as difficult production cost is high.
The content of the invention
The present invention propose a kind of early strength agent for cement concrete regarding to the issue above, shorten concrete initial set with
Final setting time, improve efficiency of construction.
Specific technical scheme is as follows：
A kind of early strength agent for cement concrete, its composition are counted as follows in parts by weight：
Calcium chloride 15-25 parts,
Methyl diethanol 3-5 parts,
Sodium metasilicate pentahydrate 10-15 parts,
Fatty acid methyl ester sodium sulfonate 3-6 parts,
Ethylene glycol 12-15 parts,
Methyl acrylate 1-3 parts,
Water 12-18 parts.
Further, the composition of early strength agent is counted as follows in parts by weight
20 parts of calcium chloride,
4 parts of methyl diethanol,
12 parts of sodium metasilicate pentahydrate,
4 parts of Fatty acid methyl ester sodium sulfonate,
13 parts of ethylene glycol,
2 parts of methyl acrylate,
16 parts of water.
Further, the composition of early strength agent is counted as follows in parts by weight
15 parts of calcium chloride,
3 parts of methyl diethanol,
10 parts of sodium metasilicate pentahydrate,
3 parts of Fatty acid methyl ester sodium sulfonate,
12 parts of ethylene glycol,
1 part of methyl acrylate,
12 parts of water.
Further, the composition of early strength agent is counted as follows in parts by weight
25 parts of calcium chloride,
5 parts of methyl diethanol,
15 parts of sodium metasilicate pentahydrate,
6 parts of Fatty acid methyl ester sodium sulfonate,
15 parts of ethylene glycol,
3 parts of methyl acrylate,
18 parts of water.
Beneficial effects of the present invention are：The present invention shortens initial set and the final setting time of concrete, improves efficiency of construction.
