SULFATE ATTACK ON CONCRETE IN SIMULATED CAST IN-SITU AND PRECAST SITUATIONS

This paper presents the results of an experimental investigation in wh ich the effect of sulfates on the strength of concrete under condition s simulating cast-in-situ and precast situations, is carried out. A ra nge of sulfate concentrations and exposure durations are adopted and t he strength loss in concrete due to the sulfate attack is experimental ly determined. The results indicate that the use of precasting in plac e of casting-in-situ is preferable, in situations exposed to sulfate e nvironments.
