Although the 28 days compressive strength was not higher than the standard structural concrete values, i.e. 45 N/mm2 , the findings of this preliminary study showed a viable technological option for the use of GRP waste in precast concrete products such as precast paving slabs, roof tiles, precast concrete wall elements, lightweight concrete, concrete paving blocks and architectural cladding materials.
The properties of panel products depend on the consistency and quality of GRP waste fibre, and access to specialised architectural cladding manufacturing facilities
