In the context of forming big continuous structures in freeforming that can be expanded without modules and connectors - what is happening in the universe of projected concrete2 is worth to be mentioned.
Here you have the seperation of fiber component (rebar) and cement/aggregate component …
The methods that create the underwater tunnels and swimming pools of today lead naturally to the methods that create the floating cities of New-VENICE and New-Atlantis of tomorrow. In the Oceanic Business Alliance we believe in the “natural evolution” of things. What will be here and big tomorrow is already under development in some special niches today… Those of the audience who have followed my discourse over the years know that among our technology pilot projects are fully functional submarines built from advanced cement composites. So it is reasonable to accept the working theory that building a “floating island” is a relative simple task for our group.
Once you leave the universe of simple cast concrete engineering - shapes and possibilities become literally limitless…
The whole idea that making things boxy and angular in modules that are bolted together - is probably just a lack of imagination and a lack of knowledge what is “out there and working fine already” …
The legacy of Zaha Hadid is in inviting us to “think beyond the box”… and coded engineering.
In the context of “projected concrete and advanced composites” you should also have a look on what was published by @Elwar back in 2015 in this thread especially the last video shows how a “surface film” can “vastly change” the overall property of a piece.
You can take a surface film as a “fiber component” introduced at the end of the build… The fiber component in a composite does not have to be mixed in - it can be performed in layers and independent of the cement and the filler components.
watch a man “walk on water” with the help of a sprayed polyurea film…
• what can you do with a polyurea sheet sprayed on the watersurface for a mile or so…in a contiuous process by a floating fabrication site ? (check how Solitaire does pipe laying to get the picture of a floating factory building oceanic infrastructure…)
• When combining 2 materials right you can make a watertank out of a cardbox … it is not about the specifics of materials - it is about the surprising properties that emerge if you COMBINE them.
• In advanced composite materials it is not about the material per se it is about the Builder getting it right.
• Building in advanced composite materials is rather an artform that requires a deep understanding and know how from the builders … so building logistics is one of the reasons why we don´t see it implemented frequently on large scale already. - The other reason is “pre-coded construction ambients” that exclude new things by default as non-code-conform.
It is the code free ambient of seasteads that allow “free choice of options” that will liberate the power of those technologies on larger scale.
Another surprising composite tech…unite modules with a film component and “unbrittle a brick”…
This is ONE method how you avoid CONNECTORS…( weaving, overlap of fiber components are others …)
