Q. Can the importance of proper consistency for placing be overemphasized?

 

A. No. Tests and experience have clearly shown that, for well consolidated, weather-resistant concrete structures, it is essential that the concrete be placed at a proper, cohesive consistency with proper consolidation. Workable concrete is readily placeable and responds well and quickly to vibration.
