Sawing a Dam in Half (on Purpose)
Practical Engineering
The chemistry of concrete is one of those things they gloss over when talking about building things out of concrete. I always found that those glossy explanations annoying. Nice of Grady to shed a little light on the subject.

Glad to hear a concrete video that uses thee correct term of "places" instead of the nonsense "pour" that 99% use, but I had to stop when he decided to throw in that concrete strength is determined by where, geographically, the materials are sourced. Nope.
I will share an usual, estoric even, perspective on this. This video is perhaps the best explanation to the layman of why I invested my time and energy into a 'needless' certification. Often I was asked, Why? and I always felt my answer to be insufficient. At least to me.
The local university, at one time known as the country's premier uni for architecture and const mgmt, offered a three year cert program. The program was the same as a degreed program, except without the lab.
The program was designed for those already working in the field. We did have access to and did use the materials lab, but it was repitious and boring. Most of the students already knew the expected results and could explain it mathematically.
(This proved that admin had made the correct decision in eliminating the lab course work.)
I am not saying everything is already learned, therefore stop pearning. Nor am I say that a person, me for instance, needn't keep studying that which is known. My object is that basic of goals; to communicate.
Yeah, the context he used implied specificity. A local batch plant used unwashed sand gotten from an ocean beach. Worked well for driveways and equipement pads, not so good for building foundations.
