2021-7-19  The process of consolidation of concrete can be carried out either with hand or with the help of vibrators. Hand consolidation: For unimportant works, the consolidation of concrete is carried out by hand methods which include ramming, tamping, spading and slicing with suitable tools. The hand methods require use of a fairly wet concrete.

self-consolidating concrete Topic

2021-5-1  Self-consolidating concrete (SCC) is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture (VMA). SCC has also been described as self-compacting concrete, self ...
