2.2 HY10L Mixing Instructions
1 Preparation:
1.1 Materials and Equipment Needed for Proper Use and Installation:
To permit rapid and continuous work with the HY10L it is recommended that all necessary tools and materials be as near to
the work area as possible. See additional equipment list for pump fill installation.
Potable water Mixing bucket Grout pump
Flow Template Kit (Part # LK400) 4 oz. (115 ml) measuring cup Plastic plugs for inlet/outlet tubes
Electric mixer 1 gallon (3L) graduated water measuring pail 2” (50mm) Cube test molds
Paddle or propeller mixing blade Thermometer (hot/cold weather) Spatula
1.2 Preparatory work:
Before beginning work with HY10L, remove all debris, oil, dirt, and moisture from the areas and couplers to be grouted.
Make sure all panels and forms are securely anchored to prevent movement during placing and curing. Verify that the HY10L
grout is not beyond the 1 year shelf life by checking the manufacturing date on the bag.
To ensure a quality structural connection it is important to provide for routine quality control during the mixing, grouting, and
installation.
NOTE: For a list of suitable equipment and accessories see the manual or contact ERICO.
1.3 Grout temperatures: Refer to Hot and Cold Weather Instructions
!!CAUTION!!
When grouting in cold weather, precautions MUST be taken to keep the HY10L from freezing (32 degrees F; 0°C), during
initial setting, as this will result in insufficient strength. Refer to Cold Weather Instructions in this manual.
2. Sample Mix:
2.1 To determine the correct amount of water to add to the HY10L, it is necessary to mix one 50 lb. (22.7 kg)
bag as a trial batch.
1. Mix the HY10L according to the mixing steps described in the next section.
2. Use 0.7 gallons of potable water to one bag of dry HY10L. [0.7 gallons is equivalent to 90 fl. oz., 2.8 qts., 2.7 L,
or 7-1/2 pop cans (12 oz. size) of water.]
3. Determine the fluidity (spread) by using the Flow Template Kit (ERICO part # LK400, described below).
4. Add additional water in small measurable increments (for example, 4 oz. or 100 ml) to get a Flow Template
measurement of 5” to 6”.
5. Remix and retest the fluidity of the HY10L after each addition of water.
6. Repeat this procedure (steps 4 to 6) until the recommended spread is achieved.
7. If the fluidity exceeds 6-1/2” as measured on the Flow Template, discard the trial batch and repeat steps 1 thru 8
with a fresh bag of HY10L, making necessary water adjustments.
8. Record the Flow Template measurement and the amount of total water needed and use this amount for further
batches of the same lot.
2.2 Using the Flow Template Kit (LK400): (See Cautions)
A Flow Template Kit can be obtained from ERICO. The Flow Template Kit is used for a modified slump test to determine the
water content for the LENTON ® INTERLOK system. The slump test consists of a 2” (51mm) diameter by 4” (102mm) tall
cylinder and a Flow Template (LK405) with preprinted circular dimension rings. This test is to be completed from start to
finish within 2 minutes and without interruption. To use the Flow Template:
1. Place the Flow Template on a flat horizontal surface and place the cylinder into the center circle.
2. Fill the cylinder to the top with the HY10L. Tap to remove air bubbles. Slowly lift the cylinder
allowing the HY10L to flow out from the bottom and onto the Flow Template.
3. To determine the fluidity, read the flow diameter (spread) off the Flow Template. Read the spread in two places,
preferably opposite to each other.
4. Average these two readings to determine the fluidity.
