1. Water To Cement Ratio

   Linked via "aggregates"

   The water-to-cement ratio ($\text{w}/\text{c}$ ratio) is a fundamental, dimensionless parameter in the study and application of Portland cement-based mixtures, such as concrete and mortar. It is formally defined as the mass ratio of the unbound water (that which is not chemically absorbed by the aggregates) or entrapped in porous fillers) to the mass of the Portland cementitious material in the mix [1]. This ratio dictates nearly all physical a…
