CARBON FIBER NETLIKE UNIT FOR REINFORCING CEMENT MORTAR AND FORMED MORTAR BODY

摘要

PURPOSE:To obtain the subject netlike unit, excellent in reinforcing effects and applicability and capable of providing high-strength cement mortar simply by embedding a small amount thereof by using carbon fiber sliver yarn coated with a binder excellent in compatibility with a cement matrix as constituent yarn. CONSTITUTION:The objective netlike unit obtained by using carbon fiber sliver yarn, coated with a binder (e.g. PVA, methyl cellulose, vinyl acetate-ethylene copolymer, polyethylene oxide, urethane or glycidyl acrylate) excellent in compatibility with a cement matrix and having preferably unevennesses on the outer surface of the yarn as constituent yarn. The aforementioned netlike unit is embedded in cement mortar to afford a molded body of carbon-fiber reinforced cement mortar.
