ACCELERATED SPLITTING-TENSION TEST FOR DETERMINING POTENTIAL 28-DAY SPLITTING TENSILE STRENGTH AND MODULUS OF RUPTURE OF CONCRETE

Recently, accelerated strength tests have been proposed for estimating the potential 28-day compressive strength of concrete. Attempts are also under way to find a means of replacing the 28-day compression test by one of the accelerated strength tests. This paper reports results of studies performed to determine if an accelerated test can be used to predict the potential 28-day modulus of rupture of concrete. In the modified boiling method adopted for this purpose, test cylinders are moist-cured for 18.5 hours, boiled for 3.5 hours, and tested in splitting tension 2 hours later. The companion 6 by 12-in. (15.2 by 30.5-cm) cylinders and 6 by 6 by 20-in. (15.2 by 15.2 by 50.8-cm) prisms are tested for splitting-tensile strength and modulus of rupture at 18 days. Correlation coefficients have been obtained for the results of accelerated splitting- tension and 28-day splitting-tension and modulus-of-rupture tests performed in both the laboratory and the field. From the limited test data available to date, it is concluded that the accelerated splitting-tension test can predict with sufficient accuracy the potential 28-day splitting tensile strength and modulus of ruputre of concrete.
