Permeability of Concrete: Function, Importance & Measures

Function of Permeability: Permeability controls the rate of moisture penetration. Higher permeability will have lower durability. Also, if the permeability is high, the water-tightness will be less. If good quality aggregates are used then permeability is low.

Parameters Controlling Tensile and Compressive

The results show that a power function adapts well q t and q u values with increasing cement content and with reducing porosity of the compacted mixture. The voids/cement ratio is demonstrated to be an appropriate parameter to assess both q t and q u of the sand-cement mixture studied.

Viscosity of Cement Slurries as a Function of Solids Content

1) apparent viscosity (η) for cement slurries as a function of volume fraction of solids (ϕ) at a shear rate (γ&) of 146 s-1. The maximum volume concentration of solids, ϕmax, is slightly lower than expected (0.65) and it seems like it decreases with decreasing shear rate (and thereby shear stress).
