Project 74: Green Building Materials

Contact Information:

Prof. Jian Yang

Project Description and Objectives:

This project primarily focuses on the use of recycled materials in modern construction. In particular, the demolition and construction waste will be recycled and utilized to replace new materials (mainly in the form of recycled aggregates) in the new construction. To compensate for the loss of strength, the recycled aggregates will be strengthened in advance. Meanwhile, scrap tire rubber will also be used as a fine aggregate to replace sand. The methods of enhancing the interfacial transition zone will be examined. The percentage of replacement, particle size distribution, and 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 and inspection will be carried out to investigate the micro-structure and composition of the material. The objectives of this project are to get students to be familiar with the production of recycled concrete that is used in modern construction such as precast concrete for modular construction and the top layer for smart motorway. The possibility of using this kind of materials for 3D printing will also be researched.

Eligibility Requirements:

Interested students should have a basic knowledge of building materials.

Main Tasks:

Becoming familiar with the production of recycled materials in modern construction.
