Sorel cement (also known as magnesia cement or magnesium oxychloride) is a non-hydraulic cement first produced by the French chemist Stanislas Sorel in 1867.. In fact, in 1855, before working with magnesium compounds, Stanislas Sorel first developed a two-component cement by mixing zinc oxide powder with a solution of zinc chloride. In a few minutes he obtained a dense material harder than ...

ratio of the weight of free-water in the mix to the weight of cement in the mix. It is computed on a weight basis by simply dividing the weight of the water in the mix by the weight of the cement in the mix. For example, for a mix containing 282 pounds of water and 564 pounds of cement the water-cement ratio would be: w/c = 282 lbs / 564 lbs = 0.5
