Concrete reinforcing
- So far we've talked about the fact that since concrete starts out in that plastic state, and then transforms to a hardened state, it makes it great building material. And in the last video, though, we talked about one of its limitations being that even though it's strong in Compression, it's relatively weak in Tension. Even just increasing the concrete's overall strength, or its compressive strength, like we discussed, results in very small jumps in that tensile strength. Now, in that segment, I did mention that there are things that we can do with the mix designs, to create concrete with higher tensile strength. Again, we talked about using stronger aggregates, or larger aggregates, or adding more cement, taking out more water, and all of these things can be manipulated to change the properties of the concrete. But they also all have limitations. Now, don't get me wrong, as we invent more and more types of chemical add mixtures, and we push the limits of leveraging different…
