Description:

The Hong Kong construction industry uses a huge quantity of concrete in building, infrastructure and other projects. Traditionally, concrete is produced with cement, aggregate and water only. But increasingly, supplementary cementitious materials (SCMs), such as pulverized fuel ash, silica fume and ground granulated blastfurnace slag, are being used to improve the fresh, mechanical and durability performance of concrete. New types of SCMs (e.g. metakaolin, rice husk ash, rushed glass powder) are also being promoted. Also, as the production of ordinary Portland cement (OPC) would generate a large amount of carbon dioxide, technologies allowing a higher replacement percentage of OPC by SCMs are being developed to produce "green concrete" to lower the carbon
footprint of cement and concrete as a contribution to reducing the overall greenhouse gas emission from the construction industry.
This conference aims to introduce the recent advances in the science, technology and practices of the production of green concrete using supplementary materials.
The theme of the seminar is "Advancement in Concrete Technology with Supplementary Materials". With speakers from renowned academics and practitioners, the seminar will address a wide variety of topics covering the development and applications of various kinds of supplementary materials in concrete.
