   en.wikipedia.org/wiki/Properties_of_concrete

   The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed.All things being equal, concrete with a lower water-cement (cementitious) ratio makes a stronger concrete than that with a higher ratio.

3. Sodium adsorption ratio - Wikipedia

   en.wikipedia.org/wiki/Sodium_adsorption_ratio

   The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils. It is an indicator of the suitability of water for use in agricultural irrigation , as determined from the concentrations of the main alkaline and earth alkaline cations present in the water.

   en.wikipedia.org/wiki/Water–cement_ratio

   A w/c ratio higher than 0.60 is not acceptable as fresh concrete becomes "soup" [2] and leads to a higher porosity and to very poor quality hardened concrete as publicly stated by Prof. Gustave Magnel (1889-1955, Ghent University, Belgium) during an official address to American building contractors at the occasion of one of his visits in the ...

9. Creep and shrinkage of concrete - Wikipedia

   en.wikipedia.org/.../Creep_and_shrinkage_of_concrete

   Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.
