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. This is known as the best Crystallizing Admixture for Concrete Waterproofing from Mapei
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).
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
APPLICATION METHOD
To ensure perfect homogenization of the product it is recommended adding Idrocrete KR 1000 as follows:
• Conveyor belt: disperse the powder of Idrocrete KR 1000 directly on the coarse aggregate conveyor belt during the loading phase.
• Premixer: add Idrocrete KR 1000 along with the other concrete components and mix as in standard production.
• Truck mixer: add Idrocrete KR 1000 into the drum of concrete mixer with a small amount of water and mix carefully before loading the concrete.
• Slurry: in the case of mixtures with low water content, it is advisable to prepare a slurry of water and Idrocrete KR 1000, to be added to the concrete to facilitate the dispersion of the product in the mix.
Account the added water in the mix design and consistency class.
