A hydraulic composition includes in relative parts by mass with respect to the cement 100 parts of cement the particles of which have a BET specific surface area comprised from 1.20 to 5 m/g; 32 to 42 parts of water; 5 to 50 parts of a mineral addition A1 the particles of which have a D50 less than or equal to 6 &#x3bc;m and selected from silica fume, metakaolin, slag, pozzolans or mixtures thereof; 90 to 230 parts of sand the particles of which have a D50 greater than or equal to 50 &#x3bc;m and a D90 less than or equal to 3 mm; 0.0001 to 10 parts of a superplasticizer, the active material concentration of which is 15% by mass.

Ultra-high performance concrete

A curing process of a concrete element including at least partially coating the element with a curing composition, the composition including a solvent and a thickening agent, the thickening agent being insoluble at a pH greater than 12 and being soluble in the solvent for a solubility range of pH, the upper limit of the solubility range being less than 11.
