Abstract: As part of the InnoWEE project (2016-2020) (Innovative pre-fabricated components
including different waste construction materials reducing building energy and minimising
environmental impacts) construction and demolition waste (CDW) was processed into fine
fractions which were then embedded into innovative high performance prefabricated
geopolymeric panels. The CDW fractions consisted of brick, concrete and mortar, and
wooden chips. Fly ash, slag and metakaolin were used as a binder and were activated by a
mixture of K-silicate and KOH. Optimized compositions were defined and panels were
produced in sizes of 50 cm × 50 cm intended for bonded contact (similar to ETICS) or 60 cm
⋅ 60 cm for ventilated façades. One type of panel was produced using mainly inorganic CDW
(ground bricks and concrete), and were designated as high density geopolymer panels (HDG).

A second type was made of at least 40% of wooden chip CDW and were designated as wood-
based geopolymer panels (WGP). The durability of both types of panels was assessed

according to the provisions of ETAG 004 and relevant standards for façade systems or wall
cladding, including freeze – thaw resistance, impact resistance, bond strength, water vapour
permeability, and capillary water uptake. Results showed that the performance of such panels
is suitable for use as façade cladding.
