Project description

Although fly ash-based geopolymer (FAGPR) binders have been increasingly explored for the last decade, there is still an urgent demand for high-performance FAGPR binder to meet the requirement of more durable and environmentally friendly infrastructure. It is also necessary to identify viable strategies to compensate for the lower early-age strength, short setting time, and less-than-ideal flowability of FAGPR, which are considered as the main drawbacks that hinder its widespread application. To this end, this proposed project will build on the team’s patented FAGPR technology and develop a novel tube/concrete composite, which features promising load-bearing capacity, durability performance, and damping properties.
