Reviews briefly the factors affecting the strength of concrete in tension and presents test results showing the effects of precompression, rate of loading, and variations of temperature on modulus of rupture. Precompression did not increase modulus of rupture, the rate of loading had a significant effect, rapid loadings gave apparently higher strengths, and low temperatures also lead to higher values for the modulus of rupture. A number of split cylinder tests were made and the results supported the view that this type of test is to be preferred to the modulus of rupture tests as a method of determining tensile strength.
