Toproc CR - Chemical Resistant concrete
Toproc CR is a high performance, microsilica concrete that has increased resistance to a wide range of chemicals.
Toproc CR is a silica fume concrete specially formulated from selected cements and chemical resisting aggregates to provide a ready-mixed concrete which is highly resisting to chemicals.
Toproc CR is superior to other Portland based concretes because of the inclusion of silica fume and its subsequent low impermeability.
Toproc CR - the tests show...
Oxygen diffusion
When tested in accordance with the Taylor Woodrow method Toproc CR concrete demonstrated that it was capable of reducing the diffusion of oxygen by up to 17% when compared to a typical RC32/40 concrete.
Chloride diffusion
When tested in accordance with the Taylor Woodrow method Toproc CR concrete demonstrated that it was capable of reducing the diffusion of chlorides by up to 67% when compared to a typical RC32/40 concrete.
Carbonation resistance
Due to the reduced permeability of the product it will have a greater resistance to carbon dioxide diffusion than an RC32/40 concrete.
Toproc CR advantages
Increased resistance to a wide range of chemicals
A reduced heat of hydration to minimise the risk of thermal cracking in large mass pours
Toproc CR exhibits less wear than conventional concrete in high abrasion environments
Toproc CR applications
Any application where concrete is likely to be attacked by chemicals
Chemical works
Effluent treatment plants
Waste storage/recycling depots
Factories using aggressive chemicals.
