CONCRETE MIX Repair Concrete DOT Europe

KORODUR Westphal Hartbeton GmbH & Co. KG

Description

Mineral, multifunctional repair concrete for traffic routes

for layer thicknesses of 50 - 600 mm

Rapid Set DOT Europe CONCRETE MIX is a high-performance, polymer-modified, fast-setting, fibre-reinforced quick-release concrete for interior and exterior use based on special cement technology. DOT Europe CONCRETE MIX can be used in accordance with DIN EN 1504-3, both for statically and non-statically relevant repairs. Ideal where fast strength, durability and low-shrinkage curing are required. DOT Europe CONCRETE MIX can be processed in layer thicknesses of 50 - 600 mm and can be loaded after just 1 hour.

More Over

Application

DOT Europe CONCRETE MIX is a multifunctional product that is also suitable for statically relevant concrete repair, repair and construction of roads, pavements, roadways, runways, bridges, parking decks, ramps, stairs, concrete and machine foundations, formwork work and industrial floors. Can also be used in wet areas. DOT Europe CONCRETE MIX is comparable in appearance to Portland cement building materials and can be processed in a similar way.

Sustainable construction

The use of DOT Europe CONCRETE MIX reduces the CO2 footprint, increases energy and resource efficiency and conserves natural resources. The production of Rapid Set cement requires 30% less CO2 emissions than conventional Portland cement.

Processing

  • Substrate: Clean the substrate, remove loose components, cement sludge, dust, acids, oil and grease. For a force-fit composite, the surface must be crack-free, even, rough and open-pored. The surface tensile strengths required in the regulations must be observed (1.0 N/mm2 must not be less than 1.0 N/mm2). Before processing, the substrate must be thoroughly pre-wetted. In the case of highly absorbent surfaces, pre-wetting may have to be repeated several times*. A film of water or puddles should be avoided. * If necessary, an acrylate-based primer can be integrated
  • Processing: Sufficient personnel and suitable equipment or tools should be available before the work begins. Mix DOT Europe CONCRETE MIX with the specified amount of water for approx. 1 - 3 minutes in a suitable forced mixer or agitator, depending on the type of processing. To mix, first add water to the mixing container. Then add DOT Europe CONCRETE MIX while the mixer or stirring whisk is running. If less water is added, the strengths increase, whereby the maximum water addition must NOT be exceeded. DOT Europe CONCRETE MIX can be processed using conventional methods. Finishing should be done as soon as possible. DOT Europe CONCRETE MIX can be smoothed, grated or textured. Installation should be carried out in a complete layer, i.e. not in layers and as evenly as possible. No installation on frozen surfaces. During compaction, air voids should be prevented as far as possible. At temperatures > 20 °C, the processing time is shortened, at temperatures < 20 °C, the development of strength can be delayed. To extend the processing time, Rapid Set SET CONTROL (retarder) can be added (see CONCRETE PHARMACY data sheet).

After-treatment

with water must be carried out immediately as soon as the surface has lost its damp shine and should be carried out repeatedly within one hour until the product has reached sufficient strength. If longer setting times occur, if temperatures are too low or if a retardant agent is used, longer post-treatment times may be necessary.
