Evaluation of 3D laser device for characterizing shape and surface properties of aggregates used in pavements

Author: Anochie-Boateng, Joseph ; Komba, Julius J ; Makulenga, N ; Maharaj, A Date: Aug 2010 A new three-dimensional (3D) laser scanning device has been acquired by CSIR Built Environment to determine rock aggregates shape and surface properties. The overall objective is to employ laser-based techniques to accurately determine ... Read more
Improvement of hardness of aluminium AA1200 by laser surface alloying

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: Jul 2010 Aluminium is vastly used in industry due to its low cost, light weight and excellent workability, but lacks in wear resistance and hardness. Laser alloying is used to improve the surface properties such as hardness by modifying the composition ... Read more
Investigation of surface properties of physico-chemically modified natural fibres using inverse gas chromatography

Author: Cordeiro, N ; Gouveia, C ; Jacob John, Maya Date: Jan 2011 Inverse gas chromatography (IGC) is a suitable method to determine surface energy of natural fibres when compared to wetting techniques. In the present study, the surface properties of raw and modified lignocellulosic fibres have been ... Read more
