New results have been obtained in the research of functional liquid cement.
Grinding agent in our country at present mainly adopts the traditional experience method to produce, research on the synthesis and distribution of grinding agent is less, failed to effective components together, resulting in grinding agent adaptability and stability, a single product, it is difficult to fully meet the production requirements of different enterprises, a few days ago, China university of mining &technology (Beijing) concrete and the environment material research institute professor wang dong people put forward the "grinding agent/functional combination design and the research and application of functional liquid cement grinding aid" project.
It is understood that the project from the molecular structure of different constituent grinding agent/functional groups on the properties of cement effect and function, and to end group activation modification principle, chemical synthesis, molecular/functional design and distribution theory as the instruction, the grinding agent molecules synthesis design and grinding agent molecular groups of the combination of the compound design, the research developed a high-performance synthetic grinding agent and a variety of functional grinding agent, improved the grinding agent product technology level. Through a series of different grinding agent for cement grinding performance, physical performance, compatibility, hydration hardening performance research on the effects of macroscopic and microscopic aspects, the research methods of exploring different grinding agent, grinding and grinding agent enhancement mechanism, etc., as well as grinding agent in the industrial test and application in practice, which provide theoretical basis for the research and application of grinding aid and technical support.
It is understood that the project has reached the expected goal, for the energy consumption of China cement industry, and promote comprehensive utilization of resources, improve the quality of cement products, and play a positive role to realize the sustainable development of cement industry.
