Title: Mechanical Properties of High-Early-Strength Concrete for Early Traffic Opening
Abstract: This study was performed to enhance mechanical properties of high-early-strength concrete using regulated-set cement for early traffic opening with various mixtures. Restraint of moisture and thermal movements of concrete pavement in actual field conditions, by external or internal restraining factors, generates tensile stresses which introduce microcracks and thus reduce the mechanical properties of concrete. Fiber reinforcement of concrete is an effective approch to the control of microcrack and crack development under tensile stresses. Three different types of regulated-set cement which recently have been used in Korea and two different types of fiber were adopted. Fibers were added and their mixtures are compared with plain high-early-strength concrete mixture. From the test results, fiber reinforced concrete was increased mechanical properties of high-early-strength concrete using regulated-set cement than the plain concrete.
