The increasing demand for construction materials along with the challenge of waste management has necessitated development sustainable utilising wastes properly. Therefore, this research examines utilisation various agricultural wastes, such as Eggshell Powder (ESP), Sawdust (SDP) and Coconut Husk (CHP), in production unfired clay blocks. Samples were made percentages wastes: 10–50% dry wt. ESP...

The development of Tissue Engineered Vessels (TEVs) is advanced by the ability to routinely and effectively implant TEVs (4-5 mm in diameter) into a large animal model. A step by-step protocol for inter-positional placement of the TEV and real-time digital assessment of the TEV and native carotid arteries is described here. In vivo monitoring is made possible by the implantation of flow probes,...

Purpose: The purpose of this paper was to find relationship between the degree of strength degradation caused by fatigue and the changes of ultrasonic wave characteristics such as wave velocity and damping coefficient. Design/methodology/approach: Epoxy-glass composites were subjected to oscillatory bending loadings with constant deflection. During fatigue procedure the force needed to achieve ...

This paper investigates the mechanical and shrinkage behaviour of concrete with recycled cement (RC) thermoactivated from waste paste concrete. Overall, compared to ordinary Portland (OPC), for same water/binder ratio, strength ultrasonic pulse velocity were not significantly influenced by incorporation RC. The elasticity modulus decreased addition RC tended increase at high content. up 15% all...
