This week, University Putra Malaysia's team unveiled their latest inventions and products at the 34th International Exhibition of Inventions, New Techniques and Products in Geneva (April 2-6, 2008), also known as the World's Largest Market-Place for Inventions.
This research is on a system for in-situ testing of high strength concrete which can be widely applied in the construction industry as it is easy to assemble & suitable for in-situ concrete strength estimation, including high-strength/ high-performance concrete.

At present, there is an increasing trend of using high-strength/high-performance concrete for major infrastructures. There is no standard test device or system that is available for in-situ concrete strength estimation of high strength / high-performance concrete. The proposed system had been developed based on extensive experimental results for normal and high-strength/ high-performance concrete. The system integrates hydraulic jacks, embedded pull-out disk and relationships between different concrete mixes to concrete strength. The relationship was established for concrete with a strength range of 40-100MPa. The system can be easily assembled and used for early concrete strength estimation that is normally required in building or structural assessment. It can be widely used by construction industry because it is easy to assemble in any traditional workshop & suitable for the in-situ concrete strength estimation, including high-strength/ high-performance concrete.
