LogP—Making Sense of the Value - ACD/Labs

a positive value for logP denotes a higher concentration in the lipid phase (i.e., the compound is more lipophilic). LogP = 1 means there is a 10:1 partitioning in Organic : Aqueous phases. Although logP is a constant, its value is dependent on the choice of the organic partitioning solvent and, to a lesser degree, on the conditions of measurement.

The Chemical Composition of Concrete

In Portland cement, 5% of its chemical composition is the gypsum mineral. The major compounds that make up Portland cement are tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite and gypsum.
