JW New High Strength Anchoring Agent
JW new high-strength anchoring agent is a new technology product jointly developed by experts from China Academy of Building Materials Science and technical personnel of our company. This product is mainly prepared with fine sand anchoring mortar, used to anchor all kinds of mines, roadways, civil air defense, concrete caverns, railways, highway tunnels and all kinds of underground works of spray anchor support, foundation reinforcement, anchoring, building anchors and other places need to anchor and emergency projects. The anchor mortar can obtain ideal bond strength in a short time, and the strength of the later period continues to increase, with good water resistance and micro-expansion performance. The performance indicators are better than the current market used in the filling material, is a set of anchoring and shotcrete and other functions as one of the new ideal building materials.

This product has high micro-expansion performance, 28d linear expansion rate ≥ 3 ‰
Use methods and precautions:
In the preparation of anchor mortar, the fine sand particles should be less than 1mm, and the ratio of fine sand to anchor agent is 1.5:1.0.
When in use, the ratio of water to lime sand should be about 0.41.
The use of the anchor mortar should be quickly stirred, timely construction, do not allow secondary mixing.
Packaging and storage:
Packed in plastic bags, each bag net weight 5~25kg, sealed storage in a dry environment, retention period of 6 months, open the bag after a run.
