本试验方法包括在实验室和现场测定自密实混凝土（SCC）的视觉稳定性指数。SCC被定义为一种高和易性混凝土，可在自身重量下流过densley钢筋或复杂结构构件，而无需振动，并充分填充空隙，而不会出现离析或过度泌水。

This test method covers determination of the visual stability index of self-consolidating concrete (SCC), both in the laboratory and in the field. SCC is defined as a highly workable concrete that can flow through densely reinforced or complex structural elements under its own weight without vibration and adequately fill voids without experiencing segregation or excessive bleeding.The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.This standard was formerly designated as provisional standard TP 80.
