In recent years, China's urbanization process accelerated, the amount of ready-mixed concrete to become the largest and most versatile building materials. As one of superplasticizer concrete essential "The Fifth Element", the amount also showed an increasing trend year by year. According to statistics, in 2012, the country's total water reducing consumption to more than 5 million tons. Among these, more than 90% of the reducing agent is formed by petrochemicals, coal chemicals and other chemical raw materials, energy consumption, high carbon emissions, especially naphthalene superplasticizer, the product also residual formaldehyde and other carcinogenic heterocyclic substance use in residential buildings cause serious pollution, endangering people's lives and health, "invisible killer."

"How to make water reducer efficient and environmentally friendly?" Beijing Construction Engineering Institute research group issues "whimsy", an innovative way to a wide range of green and renewable source of starch as a raw material, by altering the molecular structure of starch, developed a green, environmentally friendly, low-carbon biomass superplasticizer, and the first plastic, nylon used in the production process - twin screw reactive extrusion process is introduced during the preparation of water-reducing agent, instead of using the microwave reactor is heated to improve Preparation of performance. The superplasticizer prepared for high water reduction, good concrete adaptability, and from petrochemical product prices, yield, cost price is only 50% superplasticizer, naphthalene superplasticizer 90% environmentally friendly and pollution-free, in line with the basic requirements of ecological civilization construction materials development.

It is reported that the biomass can be used with Naphthalene superplasticizer, polycarboxylate superplasticizer be complex to use, and related products have been practical, economic and social benefits significantly in a number of concrete mixing station in Beijing.
