Con el fin de combinar de la mejor forma posible las características estructurales de compuestos base cemento a varios niveles y su proceso de fractura a múltiples escalas, se diseñó un compuesto híbrido de base cemento de endurecimiento por deformación reforzado con fibras (MsHySHCC), añadiendo fibra de acero en forma de gancho y fibra de carbonato de calcio (CaCO3) en SHCC reforzado con fibra de alcohol polivinílico convencional (PVA). Se evaluaron las propiedades a compresión de PVA-SHCC y MsHySHCC. Los resultados indican que el MsHySHCC diseñado tuvo un mejor rendimiento a compresión que el de PVA-SHCC. Las fibras de PVA sustituidas parcialmente por fibra de acero y de CaCO3 mejoraron los parámetros de compresión, sin embargo, una mayor sustitución de las fibras de PVA no causó una mejora al aumentar el contenido de fibras de CaCO3. Se desarrollaron dos tipos de modelos constitutivos de compresión semi-teóricos desde la perspectiva de la teoría de la mecánica del daño y la descripción matemática geométrica, respectivamente. Se encontró que ambos modelos propuestos se pueden aplicar para predecir las relaciones de tensión-deformación a compresión uniaxial de PVA-SHCC y MsHySHCCs
