Research of complex process of naphthalene superplasticizer and impact of cement paste fluidity

In this paper, an efficient naphthalene superplasticizer is obtained by improving the production process, shortening the production cycle. Considering the performance and production costs of the water-reducing agent, the optimized mixture ratio was obtained by mixing the product with different kinds of compound retarder. Meanwhile, the cement paste fluidity of the complex product in different time, cement, water-cement ratio and superplasticizer content was also determined to be compared with the commercially available superplasticizer and characterized performance of naphthalene compound water-reducing agent. The results showed that the optimal mass ratio of naphthalene superplasticizer, sodium gluconate, sodium tripolyphosphate and lignin sulfonate is 1∶0.042∶0.042∶0.305. The cement paste fluidity of the self-made naphthalene superplasticizer mixture prevails over the commercially available superplasticizer.
