How is cement used to make concrete?What are the principle types of concrete and how are they made?
Shouldn't you be asking this question in (homework help)
We added sand, rock and water to cement to make a boat ramp, diving board platform, a seawall secured with pilings that went across two lots that included a patio and boat dock. We used different concrete mixtures since the seawall was poured in a form with reinforced steel that was in the water. The cement was poured through a large plastic tube. The pilings also had a plastic tube which we had water running through to help get them into the ground. And on one the learning channels I remember that the Autobahns has held up better than our roads because it had a deeper foundation, I believe it was 2 inches deeper. I imagine that there are different mixtures for concrete depending on the purpose it is for and the weather. This is from 45 years ago memories, so check it out.
1, The development of concrete is important because allowed us to make bigger buildings. Without concrete we would have to use natural materials, reducing the height and size of our buildings. 2.Concrete is concrete. We can provide concrete of different compressive strengths and durability. Different types of cement, and admixtures can be used to provide concrete of different properties. Check out Portland Cement Associations (PCA) website as well as other cement sites. Cheers and good luck.
