Kinetics of cement: Degree of hydration or Degree of reaction?

It is so common to see the terms “degree of hydration” and “degree of reaction” in research field of cemetitious material, such as cement or blended cement, especially when we focus on the kinetics.

Here comes the question, what is the difference between the two terms? are t......

Factors affecting the reactivity of slag

The exact composition of slag varies over a range. In general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition.

Fineness

Like most of other cement materials, the reactivity of slag is......

Low reactivity and reported reaction extent of limestone in blended cement

The extent of reaction of limestone with cement clinkers is relatively low than the corresponding values of cement clinkers, the probable cause for this as stated above arise from the low solubility and low reactivity of limestone particles, though other factors of limestone, including fineness, par......
