This is the ability to consider concepts, make generalizations, and think philosophically. Concrete thinking is a necessary first step in understanding abstract ideas. First, we observe and.

Concrete foundations are used for most buildings to ensure they can be built upon. Houses, commercial buildings, and everything in between are built once a concrete foundation is laid. Concrete has been used for foundations for over a century, once builders realized how it could be used to secure a building’s construction long into the future. There are three foundation types: T-shaped: A traditional foundation method to support a structure in an area where the ground freezes.

A footing is placed below the frost line and then the walls are added on top. The footing is wider than the wall, providing extra support at the base of the foundation. Slab-on-ground: A slab is a single layer of concrete, several inches thick. It’s so easy for us to assume that once a foundation is set, students can simply build without needing creativity in the way we teach. There’s a reason we begin learning in these ways and it would do us all well to remember that. And I don’t know about you, but I was always looking for a legitimate reason to play with my food.

10 Advantages of concrete. Advantages of concrete. Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials. 10 major advantages of concrete are explained below.

1. Concrete is Economical. Compared to engineered cementitious materials used for construction, the production cost of cement concrete is very low. The overarching purpose of the CRA instructional approach is to “ensure students develop a tangible understanding of the math concepts/skills they learn.” (Special Connections, 2005) Using their concrete level of understanding of mathematics concepts and skills, students are able to later use this foundation and add/link their conceptual understanding to abstract problems and learning. Having.

Why do you need concrete examples? Abstract ideas can be vague and hard to grasp. Moreover, human memory is designed to remember concrete information better than abstract information (1).

To really nail down an abstract idea, you need to solidify it in your mind. You can do this by being specific and concrete. The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design.

Concrete thinking is the primary thinking process that we are born with. The development of abstract thinking comes later in life as we are introduced to more abstract concepts and learn to recognize the difference in concrete and abstract ideas. The biggest reason for this is that any mistakes you make in the foundation will only get worse as you go up. It’s known as compounding defects and it means that mistakes grow.

Here’s an example: You notice that your slab foundation is 3/4” out of square when you start framing.

Thus, it was now necessary to teach mathematics and geometry – and in considerable extension – at the beginning of the first cycle: it was recommended to use the concrete, experience, and induction as the first step necessary before the transition to deductive reasoning.

Using statements as elementary building blocks and deductive logic as the mortar that holds them together, we can build up large, elaborate chains of reasoning that pass, in most classrooms, for ‘knowledge’ pure and simple.

Thus, during the concrete stage, roughly covering the elementary school period, children are restricted by their dependence on concrete-empirical experience to a semiabstract, intuitive understanding of abstract propositions.

Geometry, too, must of course begin somewhere, and it is tempting to think that its starting points, the basic axioms on which the discipline of geometry is built, are logically true, true by necessity, in contrast to the contingent starting points of legal science.

Rather than demonstrate to the students their inability to generalize, to make the concept concrete so they can then handle it by memorizing, Teacher A’ directly engages their growing edge, which is expressed in their inability to move smoothly from the concrete to the abstract (which subtends the concrete).

To obtain this knowledge we must enter into some abstract Notions which, as such, are quite general and dry, and which are the two principles of Development and of the Concrete.

When you think about how learning should move from the concrete to the abstract, it is important to keep in mind that concrete is a relative term.

On the other hand, it might be argued that the teachability of the concrete forms should imply that they are taught first, but then the other abstract uses immediately follow.

  • Dang it Odell, I was drawn to your channel by the quality and sincere nature of your work and now you complete the picture by giving back to your community! This is what being an American is all about! What it means to be a giver instead of a taker! Where did he get these values? Youll have to ask him but my suspicion is he believes in a higher power, a higher call to something other than self! My wife and I teach art and its the best art class in the Nation! No college could touch her class darn it! These kids matter and their worth saving! What your looking at in videos like this is the future of Education, an education where you can GET A JOB! A GOOD JOB! Good concrete guys are impossible at times to find! Believe me. The Odells and those involved im praying for you all and your endeavors to build men and women of character, well done.

  • i don’t know why a 4th year civil engineering student like me watching this at 2 am even though i already knew the answer but who care

  • please make a strength test if only fiber was added to the cement mixture with best amount of water. no rebar. please pardon my english construction. thanks for any reply

  • This is great! If you’re young and willing to learn then go do it! Even if you don’t do construction it doesn’t hurt to know some things.
    Thank you Odell for the great information, keep trucking along.

  • I guess this is why some “new” construction projects fail. Either (1) incompetence with the wrong water % mix or (2) fraud to add more water to lower your concrete cost.

  • Dear friends, it is really very helpful video for civil engineering faculty students. It deserves your Like.
    And also i kindly please you to visit our web site to see advanced technologies: http://www.foreas.com

  • If keeping concrete wet during its curing period is essential, then how come adding extra water to the mixture in the first place, creates the weakest form in terms of compressive strength?

  • Not sure why this video was recommended by YouTube but it was interesting. I noticed in some water feature videos from other content creators that suggest concrete mixture should be mixed differently depending on where one lives based on weather conditions and if water is going to be on the concrete surface. I realize water can have an effect. But air I’m thinking is a salesman gimmick talking point. I like the fact you proofed your presentation with sample test block instead of bla bla. Thanks

  • A house is going up next door with a cast concrete foundation. When they poured the footer, they placed rebar every foot and a half or so stand up. It seemed they ran out of rebar and cut what they had into 3′ lengths and placed those along the final wall instead of the full 10-ish footers. Today, they are setting the forms for the walls and are lashing full length rebar onto those 3-footers. I’d like to know if this will have equal properties to using continuous rebar? Part of me says the short piece, which stands proud of the footer by about 2.5 feet, will tie the wall to the footer and the 2nd bit of bar will run the whole height of the wall, so it should be fine. Another part of me says, yeah, but it’s creepy. Thoughts? I guess in roads, floor slabs, and anything of any real length you’re always using multiple bars, so this should be fine.

  • Love your videos! Can you explain why submerged concrete “will set and harden just as well, or maybe even better, as if it were dry” yet demonstrates the greatest compressive strength with the smallest w/c ratio? Does it somehow not absorb as much water when the sample is completely submerged? Thanks!

  • hi my name is Gashwan i am trying to build a full concrete house including the top floor being a concrete slab i would like to know is this safe i wanna build a chill area on the roof of the house will it support?

  • Sir help me please. the foreman just put a 4″ downspout inside a 300x300mm rcc column without my consent, he put it all in my rcc columns, with a concrete slab as a roof, im anxious that it might fall during earthquake. i was wondering if it can be fixed?

  • I think your results at 7:13 was mainly affected by time. Given the same amount of time for all the specimens to cure, the one with least water would obviously be the one closest to fully cured. If you had taken the constant variable as something like percentage cured, or how dry the concrete was or something of that sort, I’m sure the results would be very different. But I don’t know how you could measure those metrics though.
