Compolite test specimens are subjected to the dual test system for the determination of water permeability and compressive strength as a quality control measure of Compolite test cubes.

Testing for Water Permeability |
Testing for Compressive Strength |
3.1 Compressive Strength
|
|
An average compressive strength of 3 MPa has been achieved for Compolite cubes with an average density 600 kg/m3 subjected to 28 days of standard moist-curing. Tests on other densities revealed that 28-day strength exceeding 15 MPa is achievable depending on the density of the mix. Studies also show that compressive strength of above 20 MPa is possible with the addition of short fiber and additives.

3.2 Durability
|
Compolite is expected to have a life span of around 100 years. Previous investigation has shown that sectioned blocks of similar foamed concrete cast 10 years ago indicated only 75 percent of the cement hydrated. It is expected that the strength would continue to increase with continuing hydration. The availability of Compolite in many cases provides an better alternative to other man-made products such as clay bricks and other insulation materials
Timber industrial ash (TIA) cement-lined pipes and fittings are developed to provide an innovative solution to the flash flood and water shortage problems. The materials formulation is designed to achieve enhanced performance in terms of strength and durability.

A web-enabled water treatment pilot plant is being experimented to control the pump and flow switches in order to monitor the quality of water supply. |
The SMS integrated environmental hazard alert system has potential to be integrated with infrastructure development projects to offer a total solution for rain water harvesting towards the mitigation of flash flood.

Affordable quality housing incorporating rainwater harvesting and water treatment offers technical and environmental advantages. The composite building system may also be adopted as a research facility for related projects. The system has potential to be developed as a mobile laboratory for electromagnetic compatibility (EMC) open area test site and the construction of lightweight concrete pavement on soft ground. The mobile laboratory made of spray-applied acoustic thermal insulation composite panels is to be integrated with wireless local area network and phone-enabled control system.
