Abstract
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.
Claims11
A process for curing a concrete element comprising at least partially coating the element with a curing composition during curing of the concrete element, said composition comprising a solvent and a thickening agent, said thickening agent being insoluble at a pH of the curing composition greater than 12 and being soluble in the solvent for a solubility range of pH of the curing composition, the upper limit of the solubility range being less than 11,
- wherein the curing composition has a first dynamic viscosity less than 0.8 Pa·s when the pH is in the solubility range and a second dynamic viscosity greater than 2 to 5 times the first dynamic viscosity when the pH is between the upper limit of the solubility range and 12, and wherein the curing composition comprises from 40% to 99.9% by mass of the solvent and from 0.1% to 5% by mass, expressed as dry extract, of the thickening agent.
