Document Type and Number:
Japanese Patent JPH06166961
Kind Code:
A
Abstract:
PURPOSE: To obtain a carbon fiber for cement reinforcement, having excellent adhesivity to cement, smoothly passing through a direct spray gun, having excellent collectability and suitable for direct spray process.
CONSTITUTION: This carbon fiber for cement reinforcement is produced by coating the surface of a carbon fiber with a polyoxyalkylene bisphenol ether as a sizing agent. A composite cement material having a flexural strength of ≥300kgf/cm2 is produced by cutting the carbon fiber to 10-50mm long and mixing to a cement matrix at a volume ratio of 1-5%.
