Investigating Transportation Policies to Reduce Air Pollution in Hong Kong

This report, prepared for Friends of the Earth (Hong Kong), examined the current transportation policies in relation to air pollution in Hong Kong. The transport policies of several cities including Seoul, Singapore, and Rome were examined in relation to reduction of congestion and air pollution. The pedestrians were surveyed and observations of traffic patterns in Hong Kong were made, then the team recommended a reevaluation of the bus system, several limited traffic zones, and several changes to the cross-harbor tunnels

Geopolymer - The Green Cement

Cement and concrete are widely used in building and construction practices throughout the world. The use of Ordinary Portland Cement (OPC) requires use of additional energy and poses environmental damage. The objective of this project is to provide a green alternative construction material to OPC by geopolymerization of industrial wastes. This study made an effort to develop a low-cost working recipe that utilizes a combination of fly ash (FA) and red mud (RM) with different additives to create a geopolymer with comparable or better performance to OPC. The effectiveness of the methodology was tested by evaluating the synthesis factors and testing the unconfined compressive strength
