Numerical simulations of permeability of plain and blended ...

Mar 27, 2017  10%  The durability of a concrete structure is principally dependent on its permeability, which governs the rate of transport of fluid through the concrete pore network. This paper presents a numerical model based on the lattice Boltzmann method (LBM) to calculate the saturated permeability of cement pastes, including blended cement pastes, wherein cement is replaced

Apr 11, 2014  The advantages of using blended cement can be broadly be divided in two categories i.e. 1. Technical Advantages. It reduces water demand and therefore water-cement ratio can be reduced. It improves workability for the same water content. The blended cements are finer as compared to OPC, therefore the permeability of concrete is less.
