ASÍ se FABRICAN los TUBOS de CONCRETO: ¿Qué los hace RESISTIR décadas ENTERRADOS sin AGRIETARSE?

How is it possible that the pipe carrying the wastewater of an entire city can survive for a hundred years buried underground without anyone seeing or inspecting it? And more importantly, why does that pipe need a steel cage, calculated down to the millimeter, to prevent it from collapsing under the weight of twenty-ton trucks passing over it every day? The answer lies in two materials that, on their own, are weak for this purpose. Concrete is very strong under compression but fractures under tension, like a cookie that can withstand being squeezed but breaks if bent. Steel, on the other hand, is very strong under tension but bends without the correct support. Together, in the exact proportion and with the correct geometry, they have become the most widely used infrastructure material on the planet for over a hundred years. Today you're going inside the plant. From the aggregate quarry and the fabrication of the steel cage to the three-point load test where each pipe is subjected to forces that simulate what it will face buried underground. If you stay until the end, you'll understand why manufacturing this object that no one appreciates is more demanding than manufacturing many things that are visible.
