However it is laborious and takes time to remove by vibration, and improper or inadequate vibration can lead to undetected problems later.

New lateral pressures prediction models are being developed (see 2 under references for details ).

Over vibrating will not cause segregation with self-consolidating concrete, however, segregation could occur if concrete is pumped over long distances.

can reduce the water-cement ratio, and the high-range water reducer (HRWR) demand.

The reduction in free water can reduce the concentration of viscosity-enhancing admixture (VEA) necessary to ensure proper stability during casting and thereafter until the onset of hardening.
