Expanding Concrete Winter
Winter grouting concrete for concrete elements
Product description
Marlon Expanding Concrete, Winter is a factory-made dry mortar product that is manufactured on the basis of Portland cement, water-reducing, freezing point depressants and expanding additives, as well as oven-dried silica sand with a controlled grain curve. Marlon Expanding Concrete, Winter comes in the variants 45 MPa and 60 MPa and with grain sizes (Dmax) 0-2 mm. Marlon Expanding Concrete, Winter only needs blending with clean, measured water at the work site, and it hardens to a lowstress, stable, frost-tolerant and waterproof concrete. The product satisfies the material requirements for environmental class E (see DS/EN 206 DK NA:2020).
- High-strength expanding concrete
- Well suited for grouting from 5 mm up to 60 mm
- Added expanding and freezing point lowering additives
- Can be used in temperturere down to -5°C
- Just add water
Marlon Expanding Concrete, Winter is well suited for grouting and jointing of, e.g. Leca clay and aerated concrete elements, grouting of machine foundations, stabilization of pylons, poles and similar projects requiring greater strengths, as well as various repair work.
To ensure the best possible adhesion for old concrete, the surface must be cleaned of any cement slurry, oil, grease or other loose impurities through, e.g. chipping, sandblasting or high-pressure cleaning, and reinforcing iron must be cleaned of rust and chlorides. The cleaned surface must be free of is and frost doing the application.
Marlon Expanding Concrete, Winter is generally mixed with 3 l of water per 25 kg dry powder, followed by effective mixing in a suitable agitator mixer. Manual mixing can be done with a low-speed drill connected to a two-bladed mixer or by hand-mixing. First pour the water in the tub, then add the dry product and mix thoroughly until you achieve a workable consistency. The mixing time is min. 5 minutes. The opening time is approx. 30 minutes at +5°C. Higher temperatures will shorten, and higher temperatures will lengthen both the processing and hardening times.
Marlon Expanding Concrete, Winter can generally be poured (depending on type) in layer thicknesses from 5 mm up to about 50 mm. Depending on the nature of the surface, large variations in the surface can result in contraction cracks.
Newly cast Expanding Concrete, Winter must be protected from heavy frost, strong winds etc.
Marlon Expanding Concrete, Winter does not tolerate temperatures below -5°C in the first curing days. Do not mix othere additives with Marlon Expanding Concrete, Winter.
Clean equipment, machinery and tools with water immediately after use. Hardened Expanded Concrete, Winter can only be removed mechanically
Marlon Expanding Concrete, Winter is subject to internal inspection according to Marlon’s quality assurance system. Subsequent measuring and mixing at the site of application is not included in quality control.
