Métodos de determinación de la cinética de hidratación mediante la retracción química y parámetros que lo influencian

Abstract Measuring chemical shrinkage provides information about the development of hydration kinetics of cementitious materials. It is also related to the degree and heat of hydration. To determine chemical shrinkage, volume change caused by the hydration reactions in a sample of cement paste under saturation conditions is quantified. There are three methods to measure this shrinkage: dilatometry, gravimetry and picnometry. These experimental procedures require simple and inexpensive equipment. There are parameters that can influence the results, such as sample thickness, water/cement ratio, ...
