2.7 HY10L Filler Material Product Specification
HY10L filler material is a specially formulated ready to use grout designed for use in the LENTON ® INTERLOK rebar splicing
system. Unauthorized use of other grouts will void all warranties, whether expressed or implied.
Product Description:
HY10L is a pre-mixed, volume stable, metallic grout. The addition of clean high quality metallic particles gives the HY10L a
ductile and reinforcing effect that enables it to withstand impact, torque, and vibrating loads. HY10L is a high-early strength
grout that offers an extended working range and can be placed at temperatures ranging from 40 to 90°F (4 to 32°C) when
installed in accordance with ERICO guidelines. Due to the excellent fluidity of HY10L, it offers the additional advantage of
being pumped with a commercially available grout pump into the LENTON INTERLOK coupler.
Technical Data:
For grout performance data please contact your regional ERICO office. HY10L grout will typically develop in excess of
8,500 psi (58.6 MPa) compressive strength in 28 days. Depending on the ambient temperature and other job site conditions,
reasonable variations in compressive strength may be encountered. The technical data is based on controlled laboratory tests.
All test specimens should be made according to ERICO guidelines.
Test samples are 2” (50mm) cube specimens cured at 72F (22°C) and tested in accordance with
ASTM C-109-90 and C-942.
PLACING CONSISTENCY:
HY10L, when mixed with approximately 11.5% water by weight of HY10L dry material, will flow to a diameter
of 5 to 6 inches (127 - 152 mm) as determined by the Flow Template Kit. Depending on the temperature,
mix size, and the specific application, more or less water may be necessary.
!!CAUTION!! Do not use more than 13.5% water by weight (0. 8 gallons or 3L per 50 lb. (22.7 kg) bag) or use
grout which has a flow template reading of greater than 6 1/2” (165 mm). A flow reading of below
5” (127 mm) will make pumping difficult and may result in insufficient filling of the coupler.
This may result in inadequate connection strength. A flow reading greater than 6-1/2” (165 mm)
will result in reduced grout strength and accompanying splice performance. A mechanical mixer
must be used to mix the HY10L. Contact ERICO for a list of suitable mixers and accessories.
Setting Time:
HY10L mixed to the placing consistency and tested in accordance with ASTM C-191, will have a time of initial setting
of about 2-1/2 hours at 68°F (20°C), (working time of 1 hour).
Packaging:
HY10L is packaged in 50 lb. (22.7 Kg) multiply moisture resistant bags for optimum performance and shelf life.
The HY10L has a shelf life of 12 months from the manufacturing date printed on the bag, when stored in
accordance with ERICO guidelines. Do not use grout that is beyond the expiration date.
Temperature Guidelines:
The preferred temperature range for the splicing system is between 50 and 80°F (10 and 27°C). As with all grouts,
the HY10L, LENTON INTERLOK coupler, and rebar must be maintained at a temperature between 40 and 90°F
(4 and 32°C). Refer to Hot and Cold Weather Installation Instructions located in this manual for complete guidelines.
