    Compared to conventional weaving, knitting minimizes the need for cutting patterns to create spatial surfaces, allows for the directional variation of material properties, and simplifies the integration of channels and openings.

    “KnitCrete” formworks use a custom, 3D-knitted, technical textile as a lightweight, stay-in-place shuttering, coated with a special cement paste to create a rigid mold, and supported by additional falsework elements such as a tensioned cable-net or bending-active splines.

Mariana Popescu is Assistant Professor of Digital Fabrication in Civil Engineering & Geosciences at TU Delft in the Netherlands. She was a workshop expert at the 6th Holcim Forum 2019 on efficient construction methods using cable-net and knitted fabric formwork.

Mariana Popescu is a computational architect and structural designer with a strong interest in innovative ways of approaching the fabrication process and use of materials in construction. Her area of expertise is computational and parametric design with a focus on digital fabrication and sustainable design.

Interior of the finished structure

Compared to conventional weaving, knitting minimizes the need for cutting patterns to create spatial surfaces, allows for the directional variation of material properties, and simplifies the integration of channels and openings.

Before joining TU Delft, she was a post-doctoral researcher at the Block Research Group (BRG) at the Institute of Technology in Architecture at ETH Zurich, involved in the NCCR Digital Fabrication, where in 2019 she also obtained her PhD, which was nominated for the ETH Medal for outstanding dissertation. 

Her research focuses on the development of KnitCrete, a novel, material-saving, labour-reducing, cost-effective formwork system for casting of doubly-curved geometries in concrete using 3D knitting. She is the main author of the award-winning KnitCandela shell and has been included as a “Pioneer” in the MIT Technology Review Innovator Under 35 global list in 2019.
