1. Comprehensive formula of water-reducing admixture for concrete
Water-reducing admixture is a type of concrete admixture. Its function is to maintain the slump of concrete basically unchanged. Under the conditions, the mixing water consumption can be reduced. There are many formulas for concrete water-reducing agents, the commonly used ones are:
1. Formula 1:
Hydroxyethyl acrylate: 25g, acrylamide: 5g, Allyl polyoxyethylene ether: 175g, sodium persulfate: 10g, neutralized with sodium hydroxide.
2. Formula 2:
Allyl polyoxyethylene alcohol ether: 40g, acrylic monomer: 30g, 10% ammonium persulfate aqueous solution 40g , neutralized with triethanolamine.
3. Formula 3:
Allyl polyoxyethylene alcohol ether: 100g, methacrylic acid: 70g, acrylic acid: 20g, 10% Ammonium sulfate aqueous solution: 50g, neutralized with sodium hydroxide.
4. Formula 4:
Methacrylic acid: 25g, allyl polyoxyethylene ether: 175g, sodium persulfate: 10g, neutralized with sodium hydroxide.
5. Formula 5:
TPEG: 180g, hydrogen peroxide: 0.63g, thioglycolic acid: 0.56g, ascorbic acid: 0.3g, acrylic acid: 182.3g , neutralized with sodium hydroxide.
6. Water reducing agent formula 6:
APEG: 180g, hydrogen peroxide: 10g, thioglycolic acid: 2.07g, itaconic acid: 10g, A Acrylic acid: 21.23g, neutralized with sodium hydroxide.
The above is for reference only. If you need more, you can find a professional concrete water-reducing agent formula and component analysis and testing agency to conduct water-reducing agent component analysis, formula restoration, etc.
2. Can water-reducing agents of different formulas be mixed?
There are many formulas of concrete water-reducing agents, and the effects of water-reducing agents of different formulas are similar. , so can they be mixed?
Generally speaking, it is not recommended to mix water-reducing agents with different formulas. Because the formula ingredients are different, the water-reducing rates will be different, and the dosage of concrete water-reducing agentIt must be controlled well. It is difficult to control the dosage when mixing water-reducing agents of different formulas. In addition, some water-reducing agents cannot be mixed. For example, polycarboxylate water-reducing agents and naphthalene-based water-reducing agents are incompatible when mixed, which will cause poor workability of concrete.
Therefore, in summary, when constructing concrete, a single formula of water-reducing agent should be selected according to construction needs to avoid mixing different formulas of water-reducing agents.
