SHORT FIBER FOR REINFORCEMENT OF CEMENT-BASED STRUCTURE COMPOSED OF POLYETHYLENE FIBER, AND CEMENT-BASED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a cement-based structure having superior tensile properties and brittle properties.SOLUTION: The cement-based structure uses a short fiber for reinforcement of a cement-based structure composed of polyethylene fibers having a weight-average molecular weight of 50,000 to 300,000 and a ratio (Mw/Mn) between the weight-average molecular weight and a number-average molecular weight of 4.5 or less.
