IDROCRETE KR 1000

Crystallizing admixture for waterproof concrete

DESCRIPTION

Idrocrete KR 1000 is a powder admixture made from special hydrophilic components which, when added to a concrete mix, reduces the permeability of hardened concrete.

Idrocrete KR 1000 is BBA certified as part of the “Mapei Idrocrete System”, agrément certificate 20/5754.

WHERE TO USE

Idrocrete KR 1000 may be used with any type of concrete when a reduction of permeability is required. Once Idrocrete KR 1000 is added to the mix, it reacts with water during the entire service life of the concrete. Idrocrete KR 1000 may be used to make concrete that is resistant to aggressive environments. The specified exposure class of the concrete must always be respected and the product cannot be used to make up for poorly designed concrete.

To have guaranteed results, Idrocrete KR 1000 must only be used in concrete that has been correctly designed respecting two basic rules for the production of impermeable concrete, which are, a water/cement ratio of 0.45 and an adequate wet curing time.

Idrocrete KR 1000 may be successfully used to produce concrete for the following applications:

✔dams;

✔bridges;

✔car parks;

✔storage tanks;

✔pipes and piles;

✔retaining walls;

✔tunnels;

✔marine structures;

✔basements and foundations;

✔swimming pools;

✔precast elements;

✔“white tanks” (weiße Wanne).

TECHNICAL CHARACTERISTICS

Idrocrete KR 1000 is a mixture of active compounds which, in the presence of water, transform the by-products of the cement hydration into crystals reducing concrete porosity and mico-cracks.

Idrocrete KR 1000 reduces the permeability characteristics of concrete. Laboratory tests have shown that adding Idrocrete KR 1000 to concrete reduces its level of capillary absorption and makes it more resistant to the hydrostatic pressure.

The crack bridging ability of Idrocrete KR 1000 allows to close microcracks up to 0.4 mm.

DOSAGE

Dosage by weight

Idrocrete KR1000 has a dosage of between 0.8 kg and 3 kg per 100 kg of cementitious material, depending on the required performance characteristics.

Different dosage rates to those recommended above must be tested beforehand on concrete by concrete trials and, in all cases, only after consulting MAPEI Technical Services Department.

In any case, we recommend to run preliminary laboratory tests prior to the industrial use of the product.

PACKAGING

Idrocrete KR 1000 is available in 20 kg and 4 kg water soluble bags.

STORAGE

Idrocrete KR 1000 maintains its properties for at least 12 months if kept sealed in its original packaging, protected from moisture.
