Fundamental Properties of Fireproofing Mortar Containg Perlite

펄라이트를 혼합한 내화모르타르의 기초적 물성

The purpose of this research is to develop the fireproofing mortar through the improved fireproofing properties. Therefore, after manufactured the mortor by changing the mixture rate of the perlite(PL) in three level, we investigated air content, flow value and compressive strength. As a result of this research, as the mixture rate was increased and the air content was also increased. But the flow ability and the compressive strength of the mortar were comparably decreased. Beside, we also found that there is efficiency of the lightweight by mixed PL.
