Investigation on the feasibility of using completely decomposed tuff as a river sand substitute for concrete production
In light of the unsustainable provision of river sand in Hong Kong and the limitations of existing river sand substitutes, Hong Kong urgently needs to discover new river sand substitutes to meet the growing demand for concrete. Hence, this project aims to investigate the feasibility of using “CDT sand” in completely decomposed tuff (CDT) as river sand substitute for concrete production.
