“…During this period, the development rate of tensile strength is relatively faster than that of the compressive strength, but at later stages the trend becomes the opposite [28]. The relationship between tensile strength and compressive strength can be described by equation (2), which has been widely used for predicting the material properties prediction [29,30].…”

“…Using Naïve Bayes and Markov Blanket algorithms, the optimum discretization method of the network was determined by measuring integral absolute error (IAE, %) shown in Eq. 4, as it is statically more sensitive than ordinary average error [17].…”

“…Where Ei and Pi are the experimental and predicted results. For the Naïve Bayes approach, five different discretization algorithms were tested to maximize the network's performance and to reduce the IAE below 10%, as to be acceptable [17]. Table 1 summarizes the IAE of the employed methods.…”

“…donde k y n son constantes obtenidas de un análisis de regresión a partir de resultados experimentales.Un ejemplo de estas expresiones es la propuesta porOluokun et al (1991) que tiene en cuenta la resistencia del hormigón a edades tempranas, entre 6 horas y 28 días: Luis V. García Ballester -Departamento de Ingeniería de la Construcción y Proyectos de Ingeniería Civil -Si f c ≥ 1000 psi (6,895 MPa): Si f c < 1000 psi (6,895 MPa) y, por lo tanto para edades tempranas: expresadas la resistencia a tracción f ct y la resistencia a compresión f c en psi.Por lo que respecta a la evolución de la resistencia a tracción a edades muy tempr anas, prácticamente no se han encontrado artículos en la bibliografía y en concreto ninguno que haga referencia a hormigones autocompactantes. Tal y como se c omentó en el apartado 2.4.1, en los ensayos realizados porVoigt et al (2006b) para analizar la evolución de la resistencia a compresión en morteros durante las primeras horas (6-8 horas en las dosificaciones utilizadas) se observa que durante el fr aguado, a medida que la mezcla va adquiriendo rigidez empieza también a haber una cierta resistencia a compresión.…”
