Prefabricated mix (fine-grained concrete) is intended for substitution of structural concrete in quality class on the level C30/37 with XYPEX ADMIX C 1000 admixture.

Product Characteristics
One-component thixotropic non-slump fine-grained concrete mix containing sealing admixtures XYPEX ADMIX C 1000

  • Applied by two methods – classical rendering or dry spraying
  • strength corresponds to quality class of concrete C30/37 according to EN 206-1,
  • minimum fallout in case of dry spraying
  • contains latently hydraulic silicon dioxide (silica fume, microsilica) enhancing concrete compactness and life
  • permanently water-resistant,
  • due to secondary crystallisation in porous system of liquefied concrete permanently seals the concrete base
  • high chemical resistance,
  • seals concrete base against oil products
  • freeze-thaw resistant
  • good adhesion to concrete base
  • partially reduced changes in volume
  • fast growth of strength
  • fit for thickness from 15 to 300 mm

MONOCRETE MONOMIX XP TH is intended especially for fabrication of the vertical water proofing membrane on the concrete base. It is practical for repairs of leaking concrete and reinforced concrete constructions. It creates the sealing membrane resistant against water, oils, organic solvents, oil products, etc. on the surface of the concrete construction.

Instruction for preparation and application.
Base. Dirt and incoherent, loose or otherwise visibly damaged concrete shall be completely removed from the base before application. Corroded reinforcement, if any, shall be cleaned of any incoherent corrosive products. Tensile strength of surface layers of the concrete base should be optimally on the level of 1,5 MPa. Before application, humidification of the surface of the base shall be properly and continually performed for at least 120 minutes. Before casting, the surface shall be dully dump, and not covered with dump shining water film.

Preparation of mix. The mix is one-component and is mixed with water only. Both the classic gravity concrete mixer and pan concrete mixer can be used for preparation. In case of preparation of small amount, the mix can be mixed with a propeller mixer driven by an appropriate electric drilling machine. Add 3,25 – 3,75 l of water to 25 kg of mix (1 bag). This mix can be applied by the socalled dry spraying – in this case it is possible to accelerate beginning of initial setting and hardening of the mix.

Workability of the mix is 50 – 60 minutes under 20 °C.
Neither temperature of base nor temperature of ambient air shall be below + 5 °C and above + 30 °C.

The mix is applied by two methods – by rendering or so called dry spraying. First layer (connecting) needs to be applied in such a way to ensure that no unfilled spaces are created behind reinforcement, in caverns etc.). After initial application it is recommended to spread the mortar into pores and uneven spaces. This can be done well with flat paint brush with short hair, or by a toothed trowel. Proper adhesion of the material to substrate in application stage is basic condition for good quality adhesion in the final state. In localized repairs it is necessary to pay appropriate attention to edge regions or repaired area, where the edge needs to be properly compacted, without entrapped air pockets or other non-homogeneities. The repair is always done from place of deepest degradation, in such a way that the final layer it to be continuous over entire area, if possible.

Surface finalization After the initial setting standard processes (smoothing by a float, steel trowel or polystyrene finisher) are used for surfacing. No additional water shall be worked up into the surface.

Surface treatment. Concrete surface shall be protected against direct sunshine and wind immediately after completion. Intensive treatment shall be carried out for at least 3 days following the casting. Optimal treatment means to cover the surface with geotextiles permanently moistened.

Specific consumption
Specific consumption of dry mortar is 1,8 kg/m2 at 1 mm of layer thickness. In spray application, it is necessary to count with loss of 10 ÷ 12 %
