Jan 06,2011·My concern was the buoyancy of pipe cast in wet concrete.Prior to the concrete setting there will be uplift forces acting on the pipe.Buoyancy is calculated as the displacement of the fluid times the density of the fluid.If the fluid is wet concrete results for this questionHow is the buoyancy of an underground concrete structure determined?How is the buoyancy of an underground concrete structure determined?It can be determined if an underground concrete structure will float or sink using basic buoyancy principles and applying them to a concrete structure.Essentially a concrete structure will notfloat if the sum of the vertical downward forces (gravitational,W) is greater than the vertical upward force (buoyant,FNPCA Buoyancy White Paper - Precast results for this questionWhat is a concrete calculator?What is a concrete calculator?The Concrete Calculator estimates the volume and weight of concrete necessary to cover a given area.Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete.Concrete Calculator

### results for this questionWhich is the best way to overcome buoyancy in concrete?Which is the best way to overcome buoyancy in concrete?One method that is used to overcome buoyancy is to increase the concretes mass (m).This is accomplished by increasing member thickness (i.e.walls and slabs).Increasing the thickness of the walls and slabs can add a significant downward gravitational force but this may not always be the best bang for your buck.NPCA Buoyancy White Paper Section 1- Buoyancy Guide(Buoyancy) When Precast Concrete
