CONCRETE MANUFACTURING PROCESS AND PANEL MANUFACTURED BY SAID PROCESS, WHERE SAID PANEL HAS A DECREASING DENSITY AWAY FROM AN EXPOSED DENSE SURFACE OF CON-CRETE OR HIGH PERFORMANCE CONCRETE (HPC)

摘要

Method for manufacturing a concrete panel wherein a mould is provided, where said mould has a design corresponding to the desired concrete panel, and where: a) a flowable (homogenous) mixture comprising a high strength concrete mixture, said high strength concrete having a compressive strength of more than 65MPa and a lightweight granular aggregate and optionally add-mixtures is prepared; b) the flowable mixture is placed in the mould; c) the mould is vibrated, whereby the lightweight material will migrate towards the surface; d) the concrete is allowed to harden and cure either in the mould or after de-moulding.
