Unformatted text preview: 2 ) How does the flexural strength obtained through a 3-point bend test compare to the flexural strength obtained through a 4-point bend test? Explain why. (6 pts) The flexural strength obtained through a 3-point bend test is higher than the flexural strength from a 4-point bend test. There is a larger area under the load in the 4-point bend test. The probability to have a flaw is higher. The sample can break under a smaller load. Processing: Portland cement is obtained through reaction of water with CaO-SiO2 TRUE or FALSE and is then heated to high temperature to form a dense solid . (2 pts) Glasses are deformed by viscous flow, not but plastic deformation. (2 pts) TRUE or FALSE...
