Study on the Workability of Self-Compacting Mortar in ‘Sinking Ball’ Test

Abstract:

Combinning at home and abroad research results, a new method of ‘sinking ball’ was put forward to evaluate the workability of self-compacting mortar (SCM). The size of ‘sinking ball’ and the volume of mortar vessel have been optimized by experiments. The results show that: when the ball with 20mm in diameter, the mortar vessel with 60mm in diameter and 160mm in heigh, the results of sinking ball test are best; Meanwhile, results indicate that the time of curve reflects the flow ability of SCM, the slope changing of curve indicates the anti-segregate ability of SCM, the integral area of curve has great relation with self-compacting ability of SCM.
