- "Concrete has next to no opinion about its shape; a wet, heavy, gloppy material, it will take any shape you give it, so long as you can hold it still for a few hours (Schjeldahl 1992). Its plasticity suggests that it might take an extraordinary variety of forms – so how did such an amorphous material end up as so many rectangular solids and cylinders? "(p.4)
- " In a flexible mould, concrete is rediscovered as a wet, sensual, and responsive material. Its relationship to its mould is no longer passive, but an active one in which concrete’s plasticity and weight play a particular and crucial role in determining its final shape."
- " In many examples, no skilled labor or sophisticated equipment are needed. As the fabric is lightweight, compact, cheap, and reusable, fabric formworks offer savings in the amount of form-and falsework material consumed, and thus in terms of transportation, storage, construction waste, and labor. "(p.34)
- "Concrete changes its color (darker or lighter) depending on how much water is retained at the surface of the casting (see Figure. 4.4, p. 57). When a permeable fabric is used to cast concrete panels, some of the excess mix water will bleed through the fabric. As previously mentioned, this can significantly improve the surface quality and appearance of the concrete. However, if the water loss is not even across the mould-face, the concrete will cure with a lighter color where more water was lost, and will be relatively darker where more water was retained at the surface of the cast."(p.198)
- "There are many benefits associated with the use of flexible textile formworks compared to rigid formwork, most notably
- formwork is lighter and easier to construct
- more complex geometries are possible, which can lead to much more structurally efficient elements
- improved concrete finish – the permeable nature of textiles reduces surface defects and produces a harder, more durable surface (see Malone (1999) and Orr et al. (2012))
- a wide variety of new and exciting architectural forms and finishes are possible."
