The shear and compressive forces are carried out through the in-situ structural screed by shear friction, wedging and/or bearing. The strength of the precast is generally between 40 and 60N/mm² and the structural topping is 25-30N/mm². Precise specification should be sought from an engineer/architect with design responsibility and professional indemnity to ensure correct calculations have been made.
Structural floor screeds can be produced either at a ready mix plant from various suppliers or on site using a forced action mixer, generally a screed pump.
