I doubt about the mainstream sustainability of it, if considered with mega structures.
Currently, more high-rise building are built then past. The base of building requires high-rigidness and compressible strength which is fulfilled by traditional concrete. But if we replace it with some flexible substance[ideally only at higher loads], It will start bending when traditional concrete would perform easily. moreover it will also affect all the application which are based on rigidness of concrete, eg, Floor tile/stone will crack open, furniture will break, your plumbing will bend etc.
so, much more research is needed. and possible whole other way of construction process has to be created to sustain new challenges.
- pas 7y agoI don't know the numbers but it doesn't sound like it makes concrete wobbly-wiggly. And ther are always shearing forces, especially with high-rises (wind), and probably this added plastic helps with that. (Less creeping cracks, better handling of repetitive stress / cyclic elastic deformation - eg bridges, roads, floors.)
- jitendrac 7y ago> it makes concrete wobbly-wiggly. That is why i wrote "some flexible substance[ideally only at higher loads]," yes, it can make positive impact on many use-cases. But I think we should focus more on the production of cement with negative or neutral CO2 yield. Cement is one of the least blamed cause of CO2 emission, but It really should be blamed.
