Quality superplasticizer concrete water-cement ratio can be reduced, reducing the slump loss of concrete, improve workability, to impart high density and excellent performance of concrete construction. Among the many series superplasticizer, the polycarboxylate superplasticizer adapt to a wide range of high water reducing low slump loss, low dosage, environmental protection, etc. [1]. According to the current knowledge and understanding of the reducing agent, reducing agent is made by means of a surfactant. Acceptance of superplasticizer concrete company can not "one size fits all" can not evasive, Polycarboxylate production, should provide each entry, batch, periodically detecting a frequency corresponding to the different test items, polycarboxylate water reducing agent synthesis, different types of superplasticizer should be focused on the acceptance of the content. Paste fluidity detection performance testing is generally not a substitute for concrete, because indicators paste it easier to meet superplasticizer, polycarboxylate water reducer sales, so there will be the same superplasticizer paste fluidity high, to maintain a good performance, but Expansion of the mixing of concrete slump and poor performance. According to the company recommends concrete water reducing performance and application requirements, each superplasticizer relatively fixed set of concrete mix, and production mix ratio close to (such as sand, liquidity, admixtures of use, etc.), polycarboxylate Save liquid, mixing each approach 15L, performance and ease of detection and protection slump concrete. If it can test samples from the mixing plant immediate sampling, the acceptance of superplasticizer better.
