Rockbond Concrete Hardener (RB CH)

Rockbond Concrete Hardener (RB CH) is a specially formulated solution of soluble silicates for use as a surface sealer, waterproofer, hardener and dustproofer for cement and concrete. When the material is sprayed or sprinkled onto cementitious surfaces, it reacts with the free lime present in the Portland cement to produce calcium silicate cements.

Description

Insoluble and inert silicates then fill and block the pores in the cement, reduce porosity and permeability, promote resistance to chemical attack, and enhance the surface strength of the concrete. The liquid is supplied in 5 or 25 litre containers and has a shelf life of 2 years.

Special Properties

  • Ready to use, quickly and easily applied.
  • Penetrates, consolidates, seals, strengthens and waterproofs cementitious surfaces.
  • Can be used on new and old concrete, inside or out.
  • Permanent: will not degrade or weaken with time.
  • Chemically reacts with the cement to produce strong and impermeable surfaces.
  • Produces concrete surfaces resistant to mechanical attack, abrasion and dusting.
  • Waterproofs cementitious surfaces, renders and concrete.
  • Provides chemical resistance to acids, waste products, aqueous solutions, salt, diesel, oil and grease.
  • Can be pigmented in a range of colours to give concrete floors an attractive finish.
  • Non flammable and economical to use. 

Uses

  • As a hardener and dustproofer for concrete floors in factories and warehouses.
  • To produce abrasion resistant concrete, car parks, pathways and roadways.
  • To weatherproof, damp proof and waterproof external renders, mortars and concrete.
  • To waterproof concrete in dams, reservoirs, tanks, tunnels and pipes.
  • For chemically resistant concrete in marine locations, chemical plants and food factories.
  • To protect concrete in farmyards, animal pens, dairies, silos and abattoirs.
  • Ideal for use as a curing compound for cement and concrete.
