Lean Concrete Structural engineering general discussion

May 28, 2010· RE: Lean Concrete. TXStructural (Structural) 28 May 10 02:36. Your fill needs to be unreinforced concrete of virtually any strength. The reason for such a high W/C is to keep workability (in this case, the ability to get it out of the truck) while using low cement content to reduce cost. Because the mix is obviously very lean, you will likely
