Factors which can accelerate the early hydration of cement , the setting in particular , such as excessively high c3a content , too low so3 content , high alkali content and the blending of pozzolana with large inner specific surface area , etc . , will result in poor compatibility of the superplasticizer with cement 凡是加速水泥初期水化的因素,特别是使水泥凝结加速的因素如c3a含量过高、 so3掺量过少、碱含量高以及掺入内比表面积大的火山灰质混合材等均使水泥与超塑化剂的相适应性变差。
