Definitions
- the present invention relates to a process for increasing the water repellency of mineral hydraulic binder compositions as well as the compositions capable of being obtained by this process and their uses in the field of construction.
- the fatty acid carboxylic esters described in this document are insoluble in water, which makes their implementation more difficult to obtain a good dispersion of the water-repellent agent in the aqueous compositions of building materials. Indeed, these compounds can only be introduced into aqueous solutions in the form of a dispersion or emulsion, which requires the addition of an emulsifier or a protective colloid which adversely affects the water-repellency property sought.
- the present invention therefore relates to a process for increasing the water repellency of a composition of hydraulic mineral binders, characterized in that a sufficient quantity of at least one salt of a monovalent cation of a carboxylic acid is added to said composition.
- Hydraulic binders are generally based on cement. They can be in the form of grout, mortar or concrete. They are used, for example, in the following applications: tile mortars, joint mortars, monolayer plasters, exterior thermal insulation systems, smoothing and leveling plasters, adhesives and plasters for insulation complexes, repair mortars, waterproofing coatings and grout for oil well cementing.
- the hydraulic mineral binders can be chosen from cements which can be of the Portland, aluminous or blast furnace type. Other compounds often added as additives to cement also have hydraulic properties such as fly ash, calcined shales. Mention may also be made of pozzolans which react with lime and form calcium silicates.
- This monovalent cation salt of a carboxylic acid can be represented by the following formula: C n H (2 ⁇ _ 1) 00- ⁇ + (I)
