Bostik CCC is a wax based concrete curing compound which incorporates a special alkali reactive emulsion breaking system. This system ensures that the emulsion breaks down to form a non-penetrating continuous film immediately upon contact with a cementitious surface. This impervious film prevents excessive water evaporation, which in turn permits more efficient cement hydration, thus reducing shrinkage and incresing durability. Once formed, the membrane will remain on the concrete surface until eventually broken down or eroded by natural weathering. Where it is required to apply a further treatment to such concrete surface, it may be necessary to remove the membrane remaining after curing by wire brushing or other mechanical means.
PROPERTIES
- Colour White
- No of components 1
- Specific Gravity 0.99 ± 0.02
- Minimum hardening temp0C 10
COVERAGE – Rate of application depends on requirements but is typically within the range of 200 to 290 ml / sq.m.
PACKAGING – 5, 20 and 200 litre drums.
- Pre mixed and ready to use. Only water is to be added at site.
- Long working time.
- Improved adhesion between blocks.
- Strong, flexible and impact resistant.
- Self-curing.
- Ready for subsequent application like plastering after 24 hours.
- Economical (required quantity is much less than conventional cement mortar).
- Exposed concrete slabs: Bostik CCC should be spray applied on to the newly placed slab as soon as possible after it is free from visible surface water, may be 1 to 2 hours after placing.
- Shuttered and precast concrete: Bostik CCC should be spray applied to all surfaces as soon as formwork has been removed or the element demolded. In all cases the nozzle of the spray should be held approximately 450 mm from the concrete surface and should be passed back and forth to ensure complete and even coverage. The pump pressure should be maintained at a level to produce fine spray.
For curing concrete in all applications wherever required. Recommended areas of use include :
- Pavements, Runways and bridge decks, Chimneys, vertical structures, airports and ports
- Bridge roof decks, retaining walls, columns, canal linings, dams etc.
- Precast piles and in all not-easily accessible areas of concreting
- Industrial floor slabs, parking and garages, terrazzo floors, warehouses etc.
ADVANTAGES
- Avoids the need for 28 days conventional water curing using hassien, polythene etc.,
- Minimizes risk of drying, shrinkage, cracks etc. at early age of concrete.
- Allows complete cement hydration.
- Easy to use and saves on labour costs.
- Free of any Chlorides and does not affect the setting time on concrete.
