Shake-free self-compacting concrete is one of high performance concrete that can consolidate under its own weight without any vibration, with the concrete mixture and later hardening having been comprehensively considered, possessing following advantages: it can
(1) improve concrete compactibility and durability, to avoid man-made factors like missing or over vibration and troubles of high percentage of reinforcement and complex structure;
(2) reduce workload and save labor and power;
(3) eliminate the vibration noises, improve environment and remit construction troubles to surrounding people;
(4) simplify working process, shorten construction period and increase efficiency.
