Revision of Quality and Performance Standard for Anchor Pins with Inlet for Epoxy Injection

Abstract

A new quality and performance standard for anchor pins with inlet for epoxy injection was proposed based on a series of experiment. Shear strength of anchor pins, pull out strength for cement mortar layers, pull out strength for concrete, resin leakage protection performance were evaluated in the study. As a result, the anchor pins whose diameter is more than 4.5 mm could meet the current standards for the anchor pins whose diameter is more than 6.0 mm.
