“Whatever you can imagine, you can also build !”
INHolland has a composite laboratory (from ship building and aeronautics). How to use a maximum of composites in architecture?The super slender glass façades of INHolland. An experimental façade.Architect: Rijk Rietveld, New York.
How to make a thin/slender façade with maximum composites, carbon fiber stiffening of glass plane? External stabilization with aramid cables.Sketches of initial experimental research phase 2005-2008.
Another type of stiffening: Result would not have desired abstract view.Sketches of initial experimental research phase 2005-2008.
At the end of the research phase: Principle of glass connection bypre-stressed aramid cables in carbon fiber tubes.
Initial ideas of feeling the pre-stressed cable through tubes in the interspace. These ideas were partly conflicting and aimed very high.
The making of the first prototype of glass panels in the research phase,2008. All edge profiles in carbon fiber.
Installation of the prototype façade mock-up in Octatube’s factory, 2008.
Final mock-up mid 2008 with aramid pre-stressed cables through carbonfiber epoxy tubes and sealed with silicone.
Perspective view as originally desired by architect Rijk Rietveld fromNew York (with randomized panels): required internal cables.
System of prestressed cables DetailsConsequences from pre-stressing for the main steel structure.Consequences of the insulated façade system of INHolland, Delft.
A later view with vertical rows of panels as advised by Octatube aramidcables for wind, deadweight suspenders in the seams.
AGC refused normal guarantee.In a dramatic change we realized thatemotional and experimental innovation canbe done in a short time of weeks or months;legal innovation with certification andcompany guarantee requires years.We were one to two years short betweentechnical innovation and legal guaranteedinnovation.
Mid May 2009 the wind loaded aramid cable is positioned outside of the aircavity of the insulated glass panels. One large innovation remains a dream.
Completion of the two main façades in August 2009.
Interior view of the two cable stayed facades.
Details of the aramid cables in the 2 main facades with separate cables.
Details of the 3rd and smallest façade in original detailing. After 3 yearsno erosion or delamination.
This minimal and extremely slender façadesystem is being developed further in themeantime with steel cables and metalframes, to be ready for the next challenge.Difficulty of non compliancy carbonfiber/silicone is emitted.
Lesson learned:Always experiment prior to or parallel to areal project. Otherwise the project will beretarded or frustrated.The better way for innovation is step-by-step, with group oriented persistence andinnovation planning.

Onderzoeksdoelstelling Materiaalconcept vaststellen met optimale combinatie van constructieve sterkte en thermische isolatie, voor realisatie van monoliete gevels Druksterkte: hoger dan 8 N/mm2 Thermische geleidingscoëfficiënt: Lambda kleiner of gelijk 0,17 W/mKPag 99 2/7/2013
Introduction Research target -- Design & development of ultra lightweight concrete Research objective -- Compressive strength: ~ 8.0 MPa; -- Thermal conductivity: ~ 0.17 W/(mK)In overall: to design a more sustainable, more cost effective, stronger; lower thermal conductivity; more durable LWAC./ Department of the Built Environment 7-2-2013 PAGE 100
Mix design Mix design concept: Target: dry density lower than 800 kg/m3. Materials • Binder (cement); Aggregates (lightweight); Fillers; Additives; Water. Water demand – density/thermal property/mechanical property / Department of the Built Environment 7-2-2013 PAGE 101

Results analysis Water permeability/ Department of the Built Environment 7-2-2013 PAGE 105
Summary An ultra lightweight aggregates concrete with a dry density of about 630-700 kg/m3 is developed; The developed LWAC shows good workability; and all the used lightweight aggregates are homogeneously distributed in the hardened concrete matrix; The developed LWAC has a 28-day compressive strength higher than 10 N/mm2, and a thermal conductivity of about 0.12 W/(mK); The developed LWAC has excellent durability, in terms of water permeability; The developed LWAC possesses the best performance, compared to the published literature data./ Department of the Built Environment 7-2-2013 PAGE 106
