Modelo para la determinación de actividad puzolánica por correlación entre: difractometría, fluorescencia de rayos X y método del cemento

Abstract

Currently one of the main materials for the addition of portland cement is the pozzolan, finely divided material together with the intimate mixture of cement provides cementitious and increases, resulting in a pozzolanic reaction or activity that results in the formation of compounds sparingly soluble in water stable and hydraulic hardening developing resistance. The amorphous silica phase is the main chemical responsible pozzolanic activity index. The present work is devoted to describe a model to estimate the pozzolanic activity correlation between diffraction-XRF with the values obtained with the method of cement. This model will carry out an online quality improvement in income and receipt of pozzolans used for the production of portland cement pozzolan and analysis time providing a qualitative and quantitative determination of this component because existing methods require wait 28 days to determine whether a pozzolan presents characteristics suitable pozzolanic
