CET-2001Q

Epoxy Resin Grout for Quartz Sensors

CET-200Q is 3-component modified epoxy grout (A: resin, B: curing agent, C: filler) specifically designed for the installation and anchoring of dynamic weighing quartz sensors (WIM sensors). Its purpose is to fill the gap between the concrete base groove and the sensor, providing stable support to ensure long-term stable operation of the sensor and extend its service life.

Product Composition and Mixing Ratio

Components:

• Component A: Modified epoxy resin (2.4 kg/barrel)
• Component B: Curing agent (0.9 kg/barrel)
• Component C: Filler (16.7 kg/barrel)

Mixing Ratio: A:B:C = 1:0.33:(5-7) (by weight), pre-packaged total weight of 20 kg/set.

Technical Parameters

Construction Preparation

Base Groove Dimensions:

• Width ≥ Sensor width + 10mm;
• Depth ≥ Sensor height + 15mm.

Base Groove Treatment:

• Remove dust and debris (use compressed air to clean);
• Wipe the groove surface to ensure dryness and oil-free conditions;
• The groove must be free of standing water or moisture.

Mixing and Construction Steps

Mixing the Grout:

1. Mix components A and B with an electric drill mixer for 1-2 minutes until uniform.
2. Add component C and continue mixing for 3 minutes until no granules remain.
3. Working Time: The mixed grout must be poured within 15 minutes.

Pouring and Installation:

• Pour the grout into the base groove, filling slightly above the sensor level;
• Ensure the sensor is centered, with grout evenly extruded on all sides;
• For gap repairs, the grout height should be slightly above the base surface.

Temperature and Mixing Ratio Adjustments

Note:

• At low temperatures (<10℃), store the materials in a 23℃ environment for 24 hours before use;
• At high temperatures (>30℃), pour in small batches quickly.

Curing and Traffic Opening

• Curing Conditions: The surface drying occurs after 24 hours, allowing sanding; full curing takes 7 days.
• Traffic Opening Time: The grout can be used 24 hours after curing (when surface temperature ≥20℃).
