WP4 - Durability of Recycled Aggregate Concretes (RACs)

Objectives: 

(i) Use experimental method to investigate the water absorption of RACs. 
(ii) Use experimental method to investigate freeze-thaw attack resistance of RACs. 
(iii) Use both the laboratory and site testing methods to investigate carbonation, chloride attack, sulphate attack, and alkali-aggregate reaction of RACs.
(iv) Develop theoretical models which can be used to describe the transport behaviour of RACs.
