Polycarboxylate water-reducing agent used in low-grade concrete
The invention discloses a polycarboxylate water-reducing agent used in low-grade concrete. The water-reducing agent includes following components, by mass, 15.0-20.0% of a polycarboxylate high-performance water-reducing agent, 0.5-2.0% of sodium thiosulfate, 0.1-1.0% of sodium carbonate, 0.05-0.1% of an organic high-molecular tackifier, 2.0-5.0% of sodium gluconate, 0.5-1.0% of sugar, 1.0-2.0% of an air entraining agent, 0.5-1.0% of a preservative and the balanced being water. According to tthe formula, the polycarboxylate water-reducing agent used in low-grade concrete, by means of other additives, the performances of the polycarboxylate water-reducing agent are improved. The water-reducing agent is enlarged in available range and can be used even in concrete being lower than C30. The water-reducing agent is not liable to cause stone exposure, water secretion, separation, hardening and the like phenomenons.
