Phoscrete HC

DESCRIPTION
PHOSCRETE HC is a two‐part cementitious concrete repair material composed of
magnesium oxide, aluminosilicates, aggregates, and reinforcing fibers (Dry Mix),
plus a liquid phosphate activator (Liquid Activator). PHOSCRETE HC is very rapid
hardening, and gains strength suitable to vehicular traffic in less than one hour at
a wide range of ambient temperatures. PHOSCRETE HC forms both a chemical
and a mechanical bond to cured concrete and to itself.
PHOSCRETE HC meets ASTM C 928, Type R3.
PROVEN APPLICATIONS
 Full depth and partial depth concrete repairs
 Interior and exterior concrete installation and repairs
 Horizontal surfaces: poured/castable applications
 Vertical and overhead surfaces: form and pour applications
 Bridge deck and parking deck repairs of reinforced concrete
 Highway concrete spall and rutting repairs
 Airport runway and apron concrete repairs
 Dowel bar retrofit, pre‐cast joint grouting, bearing locations
 Freezer floors, industrial floors, and loading dock repairs
 Expansion joint nosing construction and repairs
ADVANTAGES
 Labor and time saving material: no sandblasting of steel bars, no anticorrosion primer, no sacrificial anodes, no curing.
 Easy and accurate mixing: two components, Dry Mix in a bag and Liquid
Activator in a jug. No water, pre-extended mix. self‐consolidating, fast
setting, easy clean up with water.
 Rapid return to service: exceeds 4,000 psi (28 MPa) compressive strength
and 1,500 psi (10 MPa) bond strength 1 hour after placement at 68°F
(20°C).
 Durable: freeze‐thaw and salt scaling resistant, even when exposed to
MgCl2 and CaCl2.
 Fiber reinforced: high flexural strength and ductility.
 Strong mechanical and chemical bond to clean cured concrete and to itself
with no cold joints
 Stops rust and inhibits corrosion: converts iron oxide to metal phosphate.
 Does not out‐gas after cure: accepts sealers and polymer coatings as soon
as 15 minutes following initial set.
 Chemically stable: no added chlorides, resists chloride penetration.
 Not a vapor barrier; allows on gradeapplications.
 Environmentally friendly: no odor, no free silica.
 All temperature use – sets in temperatures cold as -5°F (-20°C)
