Mechanical Behavior of High Performance Concretes. Volume 6. High Early Strength Fiber Reinforced Concrete
This study provides an extensive database and a summary of a comprehensive experimental investigation on the fresh state and mechanical properties of high early strength fiber reinforced concrete (HESFRC). The control high early strength (HES) concrete used for fiber addition and the resulting HESFRC are defined as achieving a target minimum compressive strength of 5 ksi (35 MPa) in 24 hours, as measured from 4 x 8-in. (100 x 200-mm) cylinders. Fresh HESFRC properties tested include air content, workability (by the inverted slump test), temperature, and plastic unit weight. Tests on the mechanical properties include compressive strength, elastic modulus, flexural strength, splitting tensile strength, and fatigue life. Sixteen different combinations of parameters were investigated; the variables were the volume fraction of fibers (1% and 2%), the type of fiber (steel, polypropylene), the fiber length or aspect ratio, and the addition of latex or silica fume to the mix. Optimal mixes that satisfied the minimum compressive strength criterion, and showed excellent values of modulus of rupture, toughness indices in bending, and fatigue life in the cracked state, are identified. Potential applications in construction, repair, and rehabilitation of transportation structures are suggested. (Copyright (c) 1993 National Academy of Sciences.)
