Definitions
- the invention relates to a stable pumpable binder composition, in particular for self-leveling systems, which among other things.
- Cement and other mineral components such as Contains fly ash, slags, dusts and / or other pozzolans as well as additives and to a method for producing such a pumpable binder composition.
- Flowing mortar and pumped concrete must therefore, in addition to being easy to pump, also have a correspondingly low tendency to sedimentation.
- Another quality criterion of easily pumpable binder compositions e.g. With self-leveling screeds, it is necessary to have not only high final strengths but also high early strengths, for example at least 2 MPa after 24 hours.
- the early strength of pumpable binder compositions can, however, be increased by various additives, such as super liquid, shrinkage compensators, setting regulators and faulty mix design are significantly reduced.
- shrinkage reducers with shrinkage reducers that are frequently used being, for example, diols or polyols, in particular glycols or glycol derivatives. With such shrinkage reducers it is generally possible to achieve a significant reduction in the formation of cracks, but at the same time as a rule both the early and the ultimate strengths are significantly reduced.
- the invention now aims to provide an easily pumpable binder composition of the type mentioned which, in addition to excellent early strength and high final strength, is also distinguished by good homogeneity and a low tendency to form cracks with excellent self-leveling properties.
- the pumpable binder composition according to the invention which includes cement and others contains mineral components, such as ashes, slags and / or dusts, and conventional additives, such as sands or gravel, essentially characterized in that the binder composition • 0.1 to 5.0 wt .-% mineral salts, such as Thiosulfates,
- a stabilizer e.g. a biopolymer, especially xanthan gum and / or welan gum and
- a super liquefier e.g. Lignin sulfonates (LS), melamine sulfonic acid-formaldehyde condensates (MSFC), naphthalenesulfonic acid-formaldehyde condensates (NSFC), polycarboxylates, polyacrylic acid derivatives and / or copolymers,
- a shrinkage reducer e.g. Contains diols and / or polyols, in particular glycols and / or glycol derivatives, the details in% by weight being based on the binder.
- the configuration according to the invention is advantageously characterized in that stable pumpable mixtures have a water-binder factor (W / B factor) of 0.1 to 0.5.
- W / B factor water-binder factor
- a particularly advantageous pumpability with a rapid setting reaction was found when the pumpable mixture contains 10 to 20% by weight and in particular 15.0 to 17.0% by weight of water (based on the binder).
- the binder composition contains between 1 to 3.0% by weight of sodium thiosulfate, based on the binder, these values still improving as a result can be added when welan gum is added to the binder composition in an amount of 0.0001 to 0.005% by weight (based on cement).
- a particularly low shrinkage behavior was found if the overall mixture was selected within the scope of the binder composition according to the invention so that the binder composition contains diethylene glycol butyl ether in an amount of 3.5 to 4.5% by weight, based on the binder.
- the inventive method for producing the pumpable binder composition is characterized in that a dry mixture of binders, such as. B. Pozzolans and / or cements, mineral additives, additives, inorganic salts and biopolymers are produced, and that the storable dry mixture thus produced is mixed with water and a, in particular liquid, shrinkage compensator to produce a pumpable binder composition.
- a dry mixture of binders such as. B. Pozzolans and / or cements, mineral additives, additives, inorganic salts and biopolymers
- the storable dry mixture thus produced is mixed with water and a, in particular liquid, shrinkage compensator to produce a pumpable binder composition.
- a premix can be provided in appropriate packaging, which can only be made on site by adding water and additives.
- Set of the liquid shrinkage is mixed in a mixer to produce the pumpable cement composition. If a solid shrinkage reducer, such as neopentyl glycol, is used, it can also be added
- the dry mix can also be mixed with conventional concrete or cement additives, e.g. Water reducers, super liquefiers, setting regulators, alkali aggregate reaction inhibitors, deaerating agents, anti-freeze agents, washout preventers, corrosion inhibitors, additives for permeability control, expansion aids, drying agents, fungicides and algicides, pigments and dyes, polymers and / or other pumping aids are added.
- conventional concrete or cement additives e.g. Water reducers, super liquefiers, setting regulators, alkali aggregate reaction inhibitors, deaerating agents, anti-freeze agents, washout preventers, corrosion inhibitors, additives for permeability control, expansion aids, drying agents, fungicides and algicides, pigments and dyes, polymers and / or other pumping aids are added.
- the pumpable binder composition can also, depending on requirements, conventional concrete or cement additives, such as water reducers, superplasticizers, setting regulators, alkali aggregate reaction inhibitors, deaerating agents, antifreeze agents, washout inhibitors, corrosion inhibitors, additives for permeability control, expansion aids, drying agents, and algicides, pigments and dyes, polymers and / or further pumping aids are added.
- conventional concrete or cement additives such as water reducers, superplasticizers, setting regulators, alkali aggregate reaction inhibitors, deaerating agents, antifreeze agents, washout inhibitors, corrosion inhibitors, additives for permeability control, expansion aids, drying agents, and algicides, pigments and dyes, polymers and / or further pumping aids are added.
- the pumpable mixture was self-leveling without any additional work. A completely flat, uniform and coherent surface could be achieved. As a result, a maximum of 2 to 3 mm of water was observed on the surface over a period of about one hour, which, however, was subsequently incorporated into the poured mixture.
- a final strength of 25 MPa was measured at a maximum shrinkage of less than 400 micrometers / m after 45 days. The early course of strength until the good final strength was achieved also met all the requirements of a cementitious pump screed with high final strength and high quality.
