Definitions
- the present invention relates to the sector of additives which are used in aqueous formulations based on hydraulic binders, such as cements, concretes or mortars, in order to improve their workability.
- hydraulic binders such as cements, concretes or mortars.
- the most efficient of these handling agents are today polymers of comb structure, having a backbone of (meth) acrylic nature on which are grafted monomers having hydrophilic functions of the alkoxy or hydroxy polyakylene glycol type. These polymers are hereinafter referred to as "hydrophilic (meth) acrylic comb polymers".
- the present invention which is based on the combination of these comb polymers (meth) acrylic having a monomer grafted with a hydrophilic function, with another comb polymer (meth) acrylic but having a grafted monomer with a hydrophobic function, allows advantageously to this disadvantage. It is therefore possible to maintain the workability of an aqueous formulation based on hydraulic binders, without segregation phenomenon or loss of mechanical properties and for periods longer than 3 hours.
- Handling is defined in US 7,232,875 as the time during which it is still possible to work with an aqueous formulation based on hydraulic binders. This quantity is conventionally measured from a slump test (or "slump" in English): the height of a sample introduced into a conical mold is determined when the said mold is lifted. The greater the sag, the better the workability of the formulation; if this character is maintained over time, we speak of retention of maneuverability.
- the fluidizing effect plays against the mechanism of dispersion: the distribution of constituents is no longer homogeneous in the formulation, which negatively impacts its mechanical properties. In some cases, the initial fluidifying power is so marked that it leads to segregation that is to say to a physical separation of the various constituents of the medium. This problem is reported in WO 2007/047407.
- the document WO 2007/047407 proposes the obvious solution of adding to the formulation a setting retarding agent, which is not without posing new problems: the agent constitutes as such a new additive to be added in the formulation, its dosage must be optimized according to the amount of plasticizer used, and the resulting handling is no longer stable beyond two hours.
- hydrophobic comb (meth) acrylic copolymers when used in an aqueous formulation based on hydraulic binders in the presence of a hydrophilic comb (meth) acrylic copolymer, the dose of hydrophilic comb copolymer with respect to the prior art and without segregation or alteration of the mechanical properties: amounts greater than 0.6% by dry weight of hydrophilic comb polymer relative to the weight of cement are reached. In doing so, the handling time of the formulation has been unmatched until now: values greater than three hours, as measured from a conventional slump test, are attained.
- the two comb polymers can be pre-coformed in the form of a single product, by mixing, which has the advantage for a person skilled in the art of having at that time only one product.
