Lightweight Aggregates Manufactured with Clay

Prior research shows that using lightweight aggregates (expanded perlite) in concrete mixtures can lower thermal conductivity about 0.13 W/mK [20]. By using lightweight aggregates prepared with expanded polystyrene waste to replace the natural aggregates, the concrete´s thermal conductivity was reduced to 0.600 W/mK [21].
