Abstract:Th e paper reports length/stress measurements taken on fresh and hardened shrinkaqe-compensating concretes, cast in hot-dry environment, and exposed to early evaporation in a wind tunnel. The results obtained warrant the following deductions: The tendency of shrinkage-compensating concrete to plastic shrinkage cracking is higher than that of parallel portland cement concrete. The initial compressive stress is greatly reduced by early evaporation. The duration of exposure has a strong influence on the actual ability of shrinkaqe-compensating concrete to compensate drying shrinkage stresses. It foil ows that in hot-dry climate, curing capable of preventing evaporation should be applied immediately after casting.
