Project Description and Objectives
This project primarily focuses on the use of recycled materials in modern construction. In particular, the demolition and construction wastes will be recycled and utilized to replace new materials (mainly in the form of recycled aggregates) in the new construction. To compensate the loss of the strength, the recycled aggregates will be strengthened in advance. Meanwhile, scrap tire rubber will also be used as fine aggregate to replace sand. The methods of enhancing the interfacial transition zone will be examined. The percentage of replacement, particle size distribution, size of recycled aggregates will be studied to investigate their effects on the properties of the resulting concrete. The performances to be studied include workability, strength, and durability. MIP, SEM, XRD tests or inspection will be carried out to investigate the micro structure and composition of material. The objectives of this project are to get students to be familiar with the production of recycled concrete used in modern construction such as precast concrete for modular construction, the top layer for smart motorway, and the possibility of using this kind of materials for 3D printing.
Interested students should have basic knowledge of building materials.
Becoming familiar with the production of recycled materials in modern construction.
Completing a research report.
Delivering two research presentations (a. references review; b. technical presentation).
Submitting one paper to a journal as a co-author.
