Special polycarboxylate water reducer for high strength pipe pile concrete

Main innovations

1. The research and development of polycarboxylate water-reducing agent for pipe piles starts from the molecular conformation, action behavior, adsorption characteristics and cement hydration mechanism of cement particle surface, and systematically studies its application performance and action mechanism, which is a functional polymer. The molecular structure design of carboxylic acid admixture provides theoretical guidance and lays a good foundation for the preparation and application of polycarboxylate superplasticizer.

2. Develop polycarboxylate admixtures with super early strength, low air entrainment and rheological properties, which improve the working performance and rheological properties of high-strength pipe pile concrete, and further improve the mechanical properties of concrete to meet the needs of pipe piles. Pile production needs.

3. Solve the problems of large slump change, complex production process, high energy consumption and environmental pollution of traditional naphthalene-based, melamine-based, sulfamate-based water-reducing agents, special polycarboxylic acid for high-strength pipe pile concrete Water reducing agent realizes meeting the needs of low carbon economy, concrete construction and sustainable development.

The development of the special polycarboxylate water reducing agent for high-strength pipe pile concrete and its successful application in high-strength pipe pile concrete, from the perspective of technical benefits, the product meets the production needs of pipe pile concrete Due to the application problems in the field of piles and the stable use on site, it is feasible to vigorously promote polycarboxylate superplasticizers in the pipe pile industry; from the perspective of economic benefits, the use of special polycarboxylate superplasticizers for pipe piles can reduce the unilateral cost of pipe pile concrete. At the same time, it avoids the consumption of steam resources caused by the use of autoclave and saves the cost of steam; from the perspective of social benefits, the use of multifunctional polycarboxylate water reducing agent to produce high-strength pipe pile concrete reduces coal consumption and greenhouse gas consumption. Gas emissions have promoted the green development of the concrete pipe pile products industry.
