The shear strength of concrete is dependant on many factors including f'c, aggregate, reinforcing, and member size. A rule of thumb for the shear strength of normalweight concrete, Vc is ϕ2√fc (psi) or ϕ0.16√fc (MPa), however, Vc can vary from 0 …
consolidated concrete provides greater strength and lower permeability than poorly consolidated concrete. The compacted, low-permeability concrete created by shotcreting is the ideal concrete for structures intended to hold water. The resulting structure's concrete porosity and resulting compressive strength will easily exceed 4000 psi (27.6 MPa)
The concrete strength variation with age can be studied by different methods. The figure-1 below shows the strength variation of a concrete present at dry and wet condition. This graph is based on the study conducted by Baykof and Syglof (1976). They found that, in dry conditions, after 1 year there is no increase in concrete strength, as shown ...
