摘要：
The use of chemical admixtures in concrete was investigated to study admixture-cement compatibility. Chemical admixtures affect the properties of concrete in diverse ways, and more than one can occur at a time. It was observed that an increase in the soluble alkali content can significantly improve the stability of air void structure, particularly when a superplasticizer is added to the concrete. The results show that it is important to understand admixture-cement and admixture-admixture interactions so optimal use of materials can be achieved, admixture-cement incompatibility can be prevented.
