Product description:
The declared product is a 150 mm deep precast concrete prestressed hollow core flooring slab. Hollow core slabs are designed for a typical span of 6 metres. The declared unit can be used with or without a structural concrete topping. Thermal insulation (made of expanded polystyrene (EPS), extruded polystyrene (XPS), polyisocyanurate (PIR) or polyurethane (PUR)) may also be used. Concrete topping and thermal insulation are not included in this EPD. Precast concrete is made of cement, aggregates, water, prestressed steel reinforcement and (if needed) admixtures. Primary data for the production of precast concrete prestressed hollow core flooring slabs was collected from 10 members of the Precast Concrete Federation. This data was used to generate a mass weighted average of production for the EPD.
