Problems solved by technology
The invention provides a water-retaining shrinkage-reducing polycarboxylic acid water reducing agent. The water-retaining shrinkage-reducing polycarboxylic acid water reducing agent can obviously increase the viscosity of a solution, delay the evaporation rate of water molecules and enhance the water retention property of the solution. Concrete shrinkage reducing test results show that the water-retaining shrinkage-reducing polycarboxylic acid water reducing agent has favorable shrinkage reducing effect; compared with common ether polycarboxylic acid water reducing agents from our company, the 28d shrinkage reducing rate ratio of concrete is lowered by 79%; and when the water-retaining shrinkage-reducing polycarboxylic acid water reducing agent is used for concrete, no influence is made to the workability and strength of the concrete, and the cost performance is high. The invention also provides a preparation method of the water-retaining shrinkage-reducing polycarboxylic acid water reducing agent. The method is simple, accessible in raw materials, low in cost and high in cost performance.
