High School Residential Construction
students spent some time exploring concrete during the building materials
portion of their course. Students mixed and poured concrete to make two test
beams. One beam had steel reinforcing put in it and the other was poured
without any reinforcing. Both beams were tested and students were able to see
the difference in the types of failure that occurred between the two beams. The
beam that didn’t have any reinforcing collapsed, and the beam that was
reinforced cracked but was still able to hold the load.
Students were able see first hand the very poor tension characteristics of concrete, and were able to see how designers/builders are able to greatly improve on this with the addition of steel reinforcing. Thanks to
TNT Builders for the form material, and
