CPD庐 RAPIDCRETE (FIBER GRADE)
Chloride Permeability
DESCRIPTION
CPD庐 Rapidcrete (Fiber Grade) is a ready-to-use, fast (AASHTO T-277-831) 23掳C
setting, high strength no slump, patching material. It is 4L Water/25 kg bag
non-metallic, non-staining, and non-toxic. (1.06 U.S. gal/55 lb)..................208 Coulombs
Water Absorption
WHERE TO USE
CPD庐 Rapidcrete (Fiber Grade) is particularly useful when (M1-67-92) % Weight Gain
downtime is at a premium and where low temperatures do 4 L Water/25 kg bag...................3.67%
not allow for proper cure of ordinary cement based repair (1.06 U.S. gal/55 lb)
compounds.
Applications include, but not limited to, repairing concrete Salt Scaling
floors in factories, warehouses, parking decks and ramps, (MTO Method 1315-07) 50 cycles : 0.467 kg/m虏
loading docks areas and cold storage rooms, concrete bridge
deck repairs and concrete runway repairs. The above information is representative of actual
production runs. Independent test results may vary
from the above by approximately 卤 10 %.
BENEFITS
鈥? fast setting
鈥? no slump consistency APPLICATION
鈥? high strength Surface Preparation
鈥? excellent freeze-thaw resistance The concrete substrate to receive the patching
鈥? low permeability compound must be clean and sound. Square out the
鈥? high resistant to sulphate attack patch area minimum 6.4mm ( 1/4") and chip out all
鈥? non-toxic contaminated concrete. Soak patch area with water so
鈥? chloride free that the concrete is thoroughly damp (no free standing
water should be present). For substrate temperatures
below 10? (50? use a slurry bond coat of CPD庐
