DS-G non-shrinkage grout is a special grout produced by using high-strength cement, high-performance water-reducing agent, high-performance expansion agent and special artificial aggregate, with construction self-leveling, non-segregation, micro-expansion, early and high strength and other characteristics. Scope of application: secondary grouting of equipment seats; bolt holes, steel structure foundations, track foundation grouting, concrete structure engineering repair.

2、Slurry aggregate does not settle for a long time, and the distribution of aggregate at each level is uniform.

3, good fluidity, and 30min flow without loss, no need to apply any pressure can be self-leveling, to achieve precision grouting.

4, The contact between the grout and the grouting part does not produce cracks.

Usage

1、Mortar mixer or hand mixer to mix fully.

2、Pouring one-way continuous, without mechanical vibration.

3、When used on site, it is strictly prohibited to mix any additives and admixtures in the grout.

4、Wet maintenance 7d.

5、See the operation instructions for details.

Packing and storage

1. Double-layer packing with inner plastic and outer braid, weight 25kg per bag.

2、Store in a ventilated and dry warehouse, avoid moisture during storage. The shelf life of the product is 6 months.
