Key concepts include yield point and maximum elongation. To design a concrete mix, the properties of the materials to be used must be determined. Wood Two different types of destructive tests are performed on a wet and dry specimen each, for a total of four tests. Testing a wet and dry specimen illustrates the effects of moisture content on wood strength. An analytical lab to confirm proper material properties and design the mix.
Students make concrete according to the mix design.
In addition to slump and air content testing, four cylinders and a beam are cast for later testing. Three cylinders are tested in compression to failure and the beam is tested in bending. A strainometer is used on one cylinder to record compressive displacements. Non - destructive Schmidt hammer tests are also performed for comparison.
