ANALYSIS OF THE USE OF CONSTRUCTION AND DEMOLITION WASTE FOR DEVELOPMENT OF ALKALI-ACTIVATED MORTARS
Alkali-activated. Civil construction waste. Metakaolin. Building materials. Recycled agreggate.
The alkali-activated binder (AAB) is constantly using in researches at scientific acad-emy in the world. This material was used in large infrastructures and showed like sustainable substitute for Portland cement (PC). The AAB performance mechanical properties are high as PC. So, the construction and demolition waste (CDW) production increased substantially. The aim to this research is to study the use the recycled aggregates of CDW in alkali-ctivated mortar-based metakaolin (AAM) as partially replacing in 25 and 50% the natural aggregates of the total size of the AAM.
