Highly ductile concrete with short fibers

Brief description of the material

Highly ductile concretes reinforced with short fibers are cement-bound high-performance materials that exhibit strain-hardening properties in tension (thus they are usually called Strain-hardening cement-based composites or SHCC) and provide a strain capacity that is more than 300 times greater than that of commonly used concretes [1]. Besides their high ductility and flexural and shear strengths that clearly exceed those of conventional concrete, highly ductile concretes also show very small crack widths up to 5% of the ultimate strain, which makes these...
