- Description
- A new process for expanded perlite particle consolidation with starch binder is studied for building material applications. Compressive modulus and strength of manufactured perlite foams were characterized for a range of foam densities (0.1–0.4 g/cm³) and compared with gypsum. Compressive strength of perlite foam with a density of 0.3 g/cm³ was found to be compatible with foamed gypsum with a range of densities, 0.7–0.9 g/cm³. Failure modes under compression were identified as those characterized with longitudinal splitting and shear planes. Damage occurred during compaction was quantified using image analysis. As expected, more damage was found for a higher density of perlite foam.
