The build up method brings about progressive stiffening, hardening, and strength enhancement. Once the concrete is carefully blended and workable it ought to be positioned in forms before the mixture gets to be to rigid. In the course of placement, the concrete is consolidated to compact it within the kinds and to eradicate possible flaws, for instance honeycomb and air voids.
