Dynamic Speckle: Study of the sensitivity of the technique to different types of cement and mixing energies in the hydration process

Abstract

The objective of this work is to evaluate the incidence of different types of cement and different mixing energies in the cement hydration process. To achieve this, a prototype that reproduces the dynamic speckle technique, which consists of the analysis of the variation of the speckle pattern originated when illuminating the surface of an object with coherent light, was used. The results obtained are expressed as a function of the speed of variation of the pattern (mobility index) and are reflected in graphic curves. It was possible to establish a relationship between the peaks of highest activity and the onset of setting, as a function of cement type and mixing energy.
