“…There are many factors influencing the development of drying shrinkage, however, in literature, the most influencing three factors are: existence of relative humidity RH gradients, evolution of the pore microstructure of cementitious paste, and aggregate-paste interface (Bissonnette et al, 1999;Liu et al, 2016).…”

“…With the rapid development of human society and the economy, the service environment of modern buildings will become diversified and problematic, placing high requirements on the durability of modern cement-based materials [1,2]. Mehta [3] pointed out that the durability failure of cement-based materials was caused by internal microcracks, in which 80% were caused by non-load deformation (most of which was shrinkage), and the early deformation played a decisive role in the total deformation of cement-based materials [4][5][6][7]. Based on a large number of experimental data, Burrows et al [8] considered that alkali sulfate content and tricalcium aluminate (C 3 A) were the most important and the third most important factors affecting the shrinkage and cracking performance of cement-based materials, respectively.…”

“…It is well known that the shrinkage mechanism of cement-based materials is closely related to their pore structure. The negative pressure caused by pore water loss is the driving force of the shrinkage of cement-based materials [6,18]. Moreover, the pore size distribution, controlled by the hydration process, has a direct impact on the shrinkage of cement-based materials [19,20].…”

“…[1] La propiedad de adhesión de la fibra con la matriz de cemento adquiere una gran importancia, ya que la fibra sirve como puente entre las caras de la grieta, controlando deformaciones de alto encogimiento y aumentando la resistencia del hormigón a la flexión. [2] Con la adición de las fibras, el hormigón de alto rendimiento reforzado con fibra (HARRF) muestra una reducción de la fragilidad, que es característica de las mezclas de hormigón, presentando un comportamiento pseudo dúctil y, tras el agrietamiento, permitiendo una redistribución de las tensiones aplicadas en el material. [3] Los estudios han demostrado que el módulo de elasticidad de las fibras tiene una gran influencia sobre el esfuerzo de retracción del compuesto, y las fibras con módulos de elasticidad elevados presentan mayor resistencia a la tracción en los primeros días.…”
