Definitions

  • the invention relates to a method for the rapid hardening of lightweight concrete with additives, e.g. EPS, polystyrene, expanded clay, pumice or similar
  • additives e.g. EPS, polystyrene, expanded clay, pumice or similar
  • the object of the invention is therefore to provide a method of the type mentioned at the outset with which an acceleration of the curing process is achieved, so that a substantial reduction in the waiting time required for the follow-up of the construction activity is achieved.
  • this is achieved in that a hardening liquid consisting of water glass or mixtures of water glass and water is applied to or in the light concrete layer to be hardened.
  • the curing time for the lightweight concrete can be significantly reduced without the need for chemicals or other mixing processes.
  • the lightweight concrete is applied as a leveling layer and / or as a heat or sound insulation layer on a substrate.
  • Grain size between 5 and 20mm, preferably between 5 and 10mm.
  • the level compensating lightweight concrete layer has a very open-pored structure, e.g. you choose Grain sizes of up to 5 or 10 mm or even larger, the bulk densities of EPS lightweight concrete being selectable between 150 to 400 kg / ⁇ rr according to a variant of the invention.
  • Aggregate grains is distributed, and that the tool factor is between 0.25 and 0.35.
  • Sodium water glass or potassium water glass can also be used as the water glass.
  • Curing liquid is sprayed onto the lightweight concrete surface.
  • the hardening liquid is distributed under pressure by means of spray lances which are pushed into the middle of the lightweight concrete layer.
  • Hose lines for air drainage are also laid.
  • Drainage lines are guided and then drained off.
  • the mixing ratio of water to water glass is chosen 2: 1, 1: 1 or 2: 1.
  • Light concrete leveling layer sprayed "quick hardening liquid” such as water glass or mixtures of water with water glass, e.g. 1 part water, 2 parts water glass, or
  • the lightweight concrete level compensation such as EPS concrete
  • EPS concrete first mixed with "lack of water”
  • the added cement content is evenly distributed around the aggregate grains (EPS particles, possibly also other materials such as sand, brick split, or the like).
  • This "installation” is almost as if it were “sand”, so dry can be mixed, e.g. with tool factor 0.25-0.35. This is particularly useful for thin installation layers.
  • the material is then sprayed on site (e.g. watering can) or better spraying device with air pressure sprayers similar to the "painting tool”. Due to the lack of water during the first mixing, this material, which is not even properly moist, absorbs the accelerating liquid "greedily”, and hardens even earlier than those mixtures which are mixed with "normal” Wz factor water.
  • the extreme porosity of the lightweight concrete then selected Larger particle sizes, for example 6-20 mm
  • successfully porous hose lines of approximately 15 to 25 mm in diameter or even smaller (or larger in the case of large bed thicknesses of the lightweight concrete) are inserted into the lightweight concrete mass at a lateral distance of approximately 1.5 meters .
  • the hose ends should be able to be connected to the outside air at suitable points. Due to the extremely loose structure of the lightweight concrete, residual moisture can be routed horizontally within the structure to the porous air drainage lines in a short time and then disappear.
  • the method according to the invention is also suitable for other purposes of rapid hardening of surfaces or through-and-through hardening of lightweight concrete. Because there was the unexpected fact that even with spray lances, which are pushed into the middle of the layer, for example with meter-thick lightweight concrete, and then "distribute" the hardener liquid under pressure (eg 2 bar or more) - also there the internal hardening in every position of the Structure is possible. For example, large-scale consolidation can be made possible as a safeguard against natural forces (dams, risk of falling rocks, tunnel protection ).
  • premixed lightweight concrete materials which are mixed with retarding liquids for the transport time expenditure (for example, for a delay effect of up to 24 hours), can be transported in sacks, big bags, or loosely on the truck over long distances, in order to then be transported Bring the place to solidification or hardening within a few minutes to the extent that the securing purpose is fulfilled.
  • the "high" concentration of retarder added to the lightweight concrete mix has no adverse effects on the accelerability with, for example, water glass or water glass-water emulsions.
  • the rapid hardening processes according to the invention can also be used successfully, for example, in prefabricated house construction, so that assembly line production can be carried out undisturbed.
  • the gaps in the interior of wooden bar constructions are filled with EPS lightweight concrete (which have lambda values of 0.05 W / mK to 0.08 W / mK and are fire-proof) and during the manufacture of the wall or ceiling elements
  • EPS lightweight concrete which have lambda values of 0.05 W / mK to 0.08 W / mK and are fire-proof
