Influence of character of clinker on the early hydration process and rheological property of cement paste
AbstractInfluence of characteristics of alite and interstitial phase in five Japanese clinkers on early hydration of cement and rheological properties of fresh cement paste was investigated. The yield value of fresh cement paste increased rapidly at first due to the formation of ettringite, later due to the formation of C-S-H until it reached setting. The setting time was strongly influenced by alite intense hydration, which started when Ca(OH)2 saturation ratio in the liquid phase approached a maximum value. That position mainly was dependent upon the free CaO content in clinker and was partially dependent upon water soluble alkali content in clinker and hydraulic reactivity of alite itself. Changing the burning degree of clinker and the hydraulic modulus of raw mix, and intergrinding of clinker with quick lime are practical ways to reduce slump loss and to set an optimum setting time for concrete. All of these methods are related to free lime content for which optimum amounts are varied with burning degree of clinker and quick lime.
