- Description
- A novel mechanical behaviour of perlite/sodium silicate composites is studied. The objective was to develop new perlite composites. The flotation method was adopted for expanded perlite consolidation. For the composites development, sodium silicate dehydration behaviour was characterised with phases formed during dehydration i.e. liquid, gel, and solid phases. The water loss-time curve for dehydration was found to have three distinctive parts - linear part at an early stage for liquid phase, followed by non-linear part during a period between commencements of gel and hydrated solid phase formations, and then another linear part for hydrated solid phase. Foams as composites were manufactured with diluted sodium silicate binder for a density range of 0.2 - 0.5 g/cm³. Compressive strengths and foam densities were obtained for optimum performance as functions of two independent variables i.e. compaction ratio and binder content. One of practical milestones observed was a density of 0.3 g/cm³ at a compressive strength of 1MPa without reinforcement.
