| Abstract: | The synthesis technology of water-reducer containing polyacrylate type superplasticizer from methyl acryl-sulfonate,acrylic acid, polyethylene glycol by two steps was discussed. Testing results showed that the water ratio of concrete is 21.3% and had no loss of fluidity in 90 min when the admixing volume is 0.35% ,and its genral performance was closed to the similar products overseas. According to the market analysis and cost accounting, the raw material cost of this water reducer is 3200 yuan/t, so it has a great market prospect. |
