Abstract: Using fibers toincrease the toughness of cementitious materials is an important approach to mitigate their inherent brittleness. Glass fiber is one of the commonly-used types of fibers. Driven by its low cost, developing high-toughness glass fiber reinforced concrete can achieve the goal of cost efficiency. However, existing research has not yet achieved satisfactory effect on toughness increasing of glass fiber reinforced concrete. In this work, the matrix mix proportion which is suitable for glass fibers was designed using machine learning methods. Multiple groups of direct tensile tests were designed for different fiber dosages, fiber types, configuration directions and matrix ingredients. Through the stress-strain curves of the direct tensile tests, DIC observations and SEM observations, the toughening effect of glass fibers on concrete was explored and a type of glass fiber reinforced concrete with high toughness was designed. A high-toughness fiber glass mesh reinforced concrete with high tensile strength of 12.5 MPa and high ultimate tensile strain of 9 681 με was developed.
