Field of Application
Large volume placement,
Water resources and canal linings,
Concreting in hot, dry and windy weather,
Performing all pre-cast and cast in place concrete structures,
Performing roads and landing fields surfaces.
Properties and Effects
Providing a thin layer on concrete and decreasing the speed of water evaporation,
Increasing durability of concrete,
Reducing formation of shrinkage and cracks on concrete surface,
Reducing the effects of concrete contraction resulting from drying,
Concrete surfaces reflect the sunlight and prevent increasing temperature,
Preventing concrete surfaces from exfoliating,
Providing required amount of moisture and heat for continuing the hydration,
Having no harmful side effects on concrete surface.
Mix one part of BC65 with one part of water properly.
Instruction for use
The prepared emulsion should not be in still state for a long time. It is advisable to stir well before use.
Use a pistol, brush to cover the concrete surface with prepared mix.
Immediately after the final finishing operation or a maximum period of 30 minutes after water surface evaporation, moisten the concrete surface then cover with BC65,
In the case of concrete molding, coat the concrete surface immediately after opening the formwork.
Physical state: Liquid
Density: Approx.1.55 g/cm3
PH: Approx. 13
Solubility: In water
Storage: In capped container protected against air and frost,
Shelf life: 1 year in original package
Packaging: In 30 Kg containers.
Technical observation and application data
The exact dosage rate may be obtained by trial mixes.
Coating surfaces with BC65 must be applied immediately after performing uncovered surfaces concreting or opening the formwork. For coating again one surface which has been coated with a curing compound before, the surface must first be moistened then apply new coating,
To thicken layer of curing compound on concrete surface and preventing the rupture of curing layer resulting from vapor pressure, coat surfaces in two phases after 1 hour passing the first phase,
The resulting paint on concrete surfaces disappears 2 or 3 weeks after operation. Use warm water to wash the surfaces.
