ZWSA new anchoring agent
The new ZWSA anchoring agent is a new technical product developed by experts from the China Academy of Building Materials Science and our company’s technicians. This product is mainly mixed with fine sand to prepare anchoring mortar, which is used to anchor various mines, roadways, air defenses, concrete caverns, railways, highway tunnels and various underground engineering spray anchor support, foundation reinforcement, anchoring, construction anchors and others Places that need anchorage and rescue works, etc. The anchoring mortar can obtain ideal bonding strength in a short time, and the later strength continues to increase, and it has good water resistance and micro-swelling properties. All performance indicators are better than the potting materials currently used in the market. It is a new ideal building material that integrates anchoring and shotcreting functions.
Usage and precautions
* When preparing the anchoring mortar, the fine sand particles should be less than 1mm, and the ratio of fine sand to anchoring agent is 1.5:10.
*The ratio of water to lime-sand during use should be about 0.41.
*The anchoring mortar should be stirred quickly when used, and the construction should be done in time. No secondary stirring is allowed.
Packaging and storage
is packed in plastic bags, each with a net weight of 5-25kg, sealed and stored in a dry environment, the retention period is 6 months, and the bag is used up once after opening.
This product has high micro-expansion performance, 28d linear expansion rate ≥3‰
