I 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.)

> 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.
