A study on applicability for dynamic joint of one component sealant

Abstract

A joint between extruded cement panels that deforms due to temperature is dynamic joint, but a detailed investigation of the phenomenon occurring in the sealant applied to the joint has not been conducted. Therefore, a special one component urethane sealant which may be applicable to dynamic joints and a two component modified silicone sealant were applied to actual size specimen used extruded cement panel, and by confirming joint behavior, the presence or absence of damage to the sealants, and confirming the physical properties, the phenomenon occurring in the sealants applied to a joint between extruded cement panels was surveyed. the applicability to dynamic joint of the special one component urethane sealant was also investigated. In this report, we will report the damage and the physical property on the day after applied to the joint, one month and two years later.
