Abstract
The experimental results presented in this paper indicate that the cement/aggregate ratio, the water/cement ratio, the size of aggregate, and the rate of cooling have significant influence on the modulus of rupture of sulfur-infiltrated concrete (SIC). Using sand only as aggregate and 65% cement, SIC of over 3500 psi in flexural tension was obtained from the test of 1″ × 1″ × 4″ specimens.
