Double-curved textile reinforced concrete panels with tensile strain-hardening characteristics

The construction of buildings with fi-ee-form surfaces can be accompanied with relatively high costs. An innovative method to produce free-form surfaces in concrete is the application of double-curved precast panels produced with a flexible re-usable mould technique. Traditional placing of reinforcing bars to strengthen such panels causes...

Production of Curved Precast Concrete Elements for Shell Structures and Free-form Architecture using the Flexible Mould Method

Free-form buildings tend to be expensive. By optimizing the production process, economical and well-performing precast concrete structures can be manufactured. In this paper, a method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single element. The...

Optimization of the flexible mould process for the production of double-curved concrete elements

Free-form buildings tend to be expensive. By optimizing the production process, economical and wellperforming concrete structures and elements can be manufactured.

The use of SCC and textile reinforcement

In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...
