- this additive is a film-forming polymer comprising anionic hydrophilic groups (latex comprising hydrophilic functions).
- compositions of hydraulic mineral binders of the invention can be used in all applications for which a hydraulic binder is used. Mention may in particular be made of tile adhesive mortars, smoothing and leveling coatings, adhesives and coatings for insulating complexes, self-leveling floor coatings, repair mortars, waterproofing coatings and grout for oil well cementing.
- the latex used is a Rhoximat150 latex sold by the company Rhodia.
- colloidal suspension made up of submicron polymeric beads, resulting from the co-polymerization of styrene and butadiene, polyacrylic chains are then grafted on the surface.
- the cement used in these examples is CEM I PM-ES 52.5 cement called HTS in the following.
- the samples are mixed at a water / cement weight ratio fixed at 0.35. 5% by mass of dry extract of latex PSB150 is added in order to approximate the real cases of the adhesive mortar formulations.
- the increase in cohesion is followed by the measurement over time of the elastic modulus G 'of the sample.
- the material is subjected to a sinusoidal deformation of 1.5 ⁇ 10 ⁇ 5 5 rad, less than the critical deformation, that is to say that the cementitious paste is not destructured.
- the frequency is kept constant at 1 radian / second.
- the adjuvanted latex paste comprising hydrophilic functions acquires little mechanical strength for approximately 400 minutes, unlike the cement paste without additives.
- cementitious matrix adjuvanted with latex comprising hydrophilic functions exhibits a significant delay in setting.
- Tests are carried out by adding hydrated calcium silicates to the cement matrix.
- Figure 3 shows the decrease in setting delay obtained with an addition of 50% by weight of CSH_0.66 relative to the mass of latex. If we refer to the elastic modulus value of 300 kPa as being able to be taken as an indication of start of setting, the addition of latex multiplies the setting time by 4.3, while the latex-CSH mixture only multiplies it by 1, 7.
- Tests are carried out by mixing, before adding hydraulic binder, the C-S-H and the latex comprising hydrophilic functions.
- the premixing of the latex with C-S-H further reduces the setting time and all the more that the duration of the mixing is great.
- FIG. 4 shows the results obtained with a C-S-H_1, 5 mixed with the turbula at 25 ° C. with the latex and the amount of water necessary for mixing the cement.
- the calcium stoichiometry of C-S-H in other words the value of the coefficient a, also has an effect on the setting time. As seen in Figure 4, the lower the ratio the less the setting of the dough is delayed.
- PSB150 latex to the cement paste considerably increases the deformation tolerable by the paste since it is then about 0.02%.
- the addition of a latex-C-S-H mixture further increases the maximum deformation tolerable by the paste and all the more so since the latex and the C-S-H are mixed for a long time before adding the cement paste.
- the maximum deformation reaches 0.05%, or more than twice the tolerable deformation of the paste adjuvanted by latex only.
