Research Status and Application Performance Orientation of Polycarboxylate Superplasticizer
Being the latest generation of water-reducing agent,polycarboxylate superplasticizer can significantly improve the performance of modern concrete,and has become an important research field and development direction of concrete admixtures.Although polycarboxylate superplasticizers are widely used,they are sensitive and have design or application bottlenecks due to the impact of practical application performance requirements or the quality and parameter fluctuations of concrete raw materials.Therefore,comprehensively understanding the performance and mechanism of polycarboxylate superplasticizer is the premise of effective application.This paper firstly systematically reviewed the current research on the synthesis of polycarboxylate superplasticizers.Then,the progressive relationship between adsorption and dispersion was analyzed in detail.The mechanism of action of polycarboxylate superplasticizer was discussed as well.Finally,according to current research,the application performance orientation of polycarboxylate superplasticizer was prospected from the perspective of robustness,compatibility,and functionalization.
