2.5 Pump Fill Installation Instructions For HY10L Filler Material
12) Once the HY10L has set (usually the next day), the plugs can be removed from the inlet and outlet tubes. The depression
that is left in the tube openings can then be filled with a standard non-metallic mortar. A non-metallic mortar is suggested
for this application to prevent unsightly rust stains that will develop on the surface of the panel or areas that were
grouted. Exposed HY10L will show rust stains. Any exposed HY10L should be covered by plain mortar or other coating
after the HY10L has solidified.
13) Clean grout pump immediately after use with plenty of clean flushing water. Fill the hopper with water and operate the
pump until the water is flowing cleanly and clearly from the nozzle. Rinse off all exterior surfaces with clean flushing
water. Never allow the grout to harden inside the hopper, hose, or nozzle as this will damage the pump.
14) The decision to remove bracing following grouting must be determined solely by the Structural Engineer.
In order to ensure a quality structural connection, it is important that the grouted couplers in a precast panel or member
be secured and undisturbed by movement, shock, or vibration until the HY10L has reached a compressive strength of
at least 3000 psi (21 MPa). Typically this will occur after 1 day at 68°F (20°C), however, this time will vary depending on
the temperature and job site conditions. In cold weather, the curing time will be significantly lengthened (2 or more days
at 40°F (4°C)), therefore, the bracing time may need to be increased. It is strongly recommended that the compressive
strength of the HY10L be checked under job site curing conditions according to the procedures outlined in ASTM C-109
before proceeding with upper story erection.
!!CAUTION!!
Horizontal Applications:
1) For Horizontal Pump Fill application make sure coupler is sealed sufficiently before pumping the grout into it.
2) Make sure that the rebar is inserted completely into the coupler for the application.
3) Make sure that the coupler is completely filled with grout and that a smooth continuous stream of grout is flowing
from the outlet ports with no air bubbles.
!!CAUTION!!
Refer to Cautions noted under Gravity Fill Installation Instructions for HY10L Filler Material for additional cautions and
information.
