APPLICATION OF AN IN-SITU MEASUREMENT METHOD USING ENSEMBLE AVERAGING TECHNIQUE TO MATERIAL DEVELOPMENT

Abstract

An in-situ measurement method using ensemble averaging technique, i.e., EA method, is applied to evaluate absorption characteristics of multi-functional interior materials using porous mortar in development phase. First, absorption characteristics of small specimen are measured by EA method in a reverberation room, and the repeatability of the measurement is confirmed. Next, absorption characteristics of eight kinds of porous mortars with different fine aggregate and porosity are measured by the method, and their absorption characteristics are compared with each other. Finally, the effect of finishing material on absorption characteristics of the porous mortar is examined.
