ROCKBOND ADMIX 801 (RB A801) powder is blend of waterproofing and water reducing admixtures that has been specially designed for use with Portland cement grouts and flowing concretes. The compound, when mixed with cementitious materials, dramatically reduces the passage of water and aggressive chemicals through the pores and capillaries of the hardened cement. The powder is ready to use, supplied to order, packaged in moisture proof, durable bags and has a shelf life of five years.
Can be packaged in water soluble bags for convenient handling.
Readily dispersed and incorporated into cement and concrete mixes.
Produces grouts and concretes that are self compacting at low water/cement ratios.
Reduces the air content, bleeding, segregation and shrinkage of flowing materials.
Will increase the compressive, tensile, and mechanical strength of cementitious materials.
Produces dense, weatherproof, waterproof, impermeable and durable concrete.
Reduces carbonation in concrete, and attack by atmospheric pollution and acid gases.
Improved resistance to sulphate, chloride and chemical attack.
Enhanced protection against adverse weather conditions, and prevents frost attack.
Prevents staining, microbial growth and efflorescence.
High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.
For use as an admixture for site batched flowing mixes to waterproof mass concrete, structural concrete, concrete foundations, tunnels, culverts and pipes.
To waterproof water retaining structures, dams, reservoirs, tanks, swimming pools and water handling and storage facilities.
To prevent dampness in underground concrete, brick walls, cellars and basements.
To protect concrete against frost, weathering and adverse climatic conditions.
To protect concrete in ground water containing aqueous chemicals, sulphates and nitrates.
To protect reinforced concrete in marine environments from salt water and chlorides.
To produce flowing, high strength, waterproof cementitious materials.
To produce chemically resistant, durable grouts and concretes.
