Mix design methodology for self-compacting flexible-fiber reinforced concrete based on rheological and mechanical concepts

A new design methodology for self-compacting flexible fiber-reinforced concrete (SCFFRC) based on rheological criteria, specifically the plastic viscosity of the suspension, is developed. Firstly, the effect that the flexible fiber produces on the plastic viscosity in Newtonian suspensions is studie...
