The research of adaptability between super plasticizer and cement

The phenomenon of poor adaptability existing between super plasticizer and cement often appears in high performance concrete and commercial concrete.This kind of phenomenon takes place particularly in high performance concrete with low water-cement ratio and less mixed water.Herein,experimental studies on cement of different factories were carried out concerning the fluidity of cement and the different properties of cement mortar mixed with super plasticizer in order to state the adaptability of different cement to the super plasticizers in application.Results show that the cement with good adaptability to plasticizer needs smaller quantity of plasticizer mixed in mortar and concrete,whose strength is higher,workability is better,and cost is lower in comparison with that of the cement with poor adaptability between cement and super plasticizer.
