- •
PCM vacuum impregnation is very successful for expanded clay lightweight aggregate.
- •
Polyester resin coating is able to retain all of the impregnated PCM from leakage.
- •
Resin coating is chemically stable and neutral, also improving thermal conductivity.
- •
Novel combination of geopolymer and thermal energy storing aggregates evaluated.
- •
ME-LWA has a high energy storage capacity of 157 J/g.
