The objective of this study is to investigate how the varieties of consistency of fresh concrete influence on the plastic shrinkage in dry condition. The test was conducted under the controlled chamber in which the temperature was kept at 25 ${pm}$2$^{circ}C$, the humidity 35 ${pm}$3%, and the wind velocity 4.0 ${pm}$0.5m/sec. The results obtained from the test are as follow. 1) The rate of evaporation was highest at 2-3 hour after casting, and decreased gradually. 2) The plastic shrinkage was increased as to the slump values. The shrinkage rate was very highest at 2-4 hour and hardly showed any changes after 6 hour. 3) The recommendation for good cloncrete is that slump value should be as low as possible in construction.
