2.1 Potential Applications
|
Potential applications include all types of insulation work, especially sound proofing applications in roofing and ceiling panels, cavity walls and as highway noise barriers. Some experimental acoustic thermal insulation composite panels are shown in figures below according to the typical cross section of composite panel.
Compolite is also suitable for special roof deck with enhanced acoustic thermal insulation and water proofing properties. Compolite of density between 250 - 550 kg/m3 is primarily used for thermal insulation or fire protection. It uses only cement (or with a small proportion of sand), water and foam for insulation board with the same insulating properties as man-made polystyrene, polyurethane or mineral wool, with no hazardous elements to health and environment.

The innovative formwork and web-pipe reinforcement system is to enhance quality and productivity in the construction process. The spray-applied coating on the EPS insulation panels provides additional resistance to moisture for external walls and basement.

Innovative synthesis and utilization of the micronised silica developed in this project is a potential alternative to silica fume in the manufacturing of advanced biomass composites and cementitious products including cement-lined pipes for rain water harvesting and flood mitigation system.

Blended Cement containing Micronised Silica as Binder |
The raw materials for spray-applied coating comprise mainly fine sand mixed with natural fiber and filler, blended cement containing micronised silica as the binder and foam to achieve controlled density.

2.2 Foam Generation
|
Foam generation requires a foaming agent and a foam generator. Foaming agent is based on a protein-hydrolisation and is biodegradable. It causes no chemical reaction with the surrounding matrix but serves solely as wrapping material for the air to be encapsulated in the cementations biomass composite. A foam generator is developed from a compressed air vessel incorporating a foaming compartment that allows the foaming agent to be agitated by a stream of compressed air.

Experimental foam generation for Controlled Density Compolite |
A water permeability test system, which has been developed, based on ISO/DIS 7031 is being upgraded with microcontroller and to be calibrated against a related test system based on DIN 1048.
