• Resumen

  • Alkali-activation or geopolymerisation of construction and demolition waste (CDW) provides a useful way of recycling that can form an important step towards waste management. This chapter evaluates the suitability of waste brick and waste concrete as source materials for the synthesis of alkali-activation or geopolumerisation technology. The mechanical properties of the prepared geopolymer samples are suitable for use on an industrial scale. Efflorescence, however, is an issue that should be considered and controlled.
