Double-curved precast concrete elements: Research into technical viability of the flexible mould method

The production of precast, concrete elements with complex, double-curved geometry is expensive due to the high costcosts of the necessary moulds and the limited possibilities for mould reuse. Currently, CNC-milled foam moulds are the solution applied mostly in projects, offering good aesthetic performance, but also resulting in waste of material...

A flexible mold for double curved precast concrete elements

The manufacturing of double curved precast concrete elements is still expensive, due to the high costs and limited possibilities for repetitive use of the molds or formwork. The goal of a PhD project recently initiated at TU Delft is to develop a production method that overcomes these difficulties by enabling the mold to be used many times and...
