(2) Discuss common defects such as surface voids, placement lines, honeycombs, and others, and how to minimize their occurrence when using SCC;
(3) Explain how special care in the selection of the formwork materials, mix design, and placement methods can lead to blemish free-walls for surfaces designated as architectural concrete.
(4) Summarize methods for evaluation of surface finish, including a proposed image analysis methodology on formed surfaces of concrete cast with Z-shaped elements.

Phase change materials (PCMs) have been widely proposed to enhance building energy efficiency, as they can regulate the in-door temperature when used in building envelopes. To be incorporated in concrete or masonry, PCMs have to be encapsulated or stabilized in lightweight porous inclusions.

The mechanisms of PCMs-stabilization in different inclusions will be introduced, and the interactions between PCMs carrying inclusions and concrete/block matrix will be illustrated. Strategies of adding PCMs without reducing the strength of construction materials will be discussed. The overall thermal properties and energy efficiency of PCMs-incorporated concrete will also be demonstrated.
