ON THE MECHANICAL PROPERTIES OF REINFORCED CONCRETE BEAM USING EXPANSIVE CEMENT

Expansive cement was used in an attempt to improve the mechanical properties of a concrete beam. Thirteen beam specimens, using two types of calcium sulpho-aluminate expansive additive in the proportions 0-15 percent of total cementing material by weight, were tested. Details of the test beams and the reinforcement are given. It is shown that the expansive additive mixture has no effect on the deflection of reinforced concrete beams and that an increase in expansive additive content increases the cracking load of a reinforced concrete beam. The rate of growth of the widths of cracks tends to decrease as the mixture of expansive additive increases.
