LZ 701
LZ 701 is composed of inorganic material, which can be used for high strength grouting material; The product is a powder compound grouting material. After mixing with water, it forms a kind of grouting material with shrinkage compensation and thixotropy. The compressive strength and fluidity can be adjusted by modifying the water-cement ratio during pulping. It is a composite product in environmental safety, strong environmental adaptability, early strength and late strength are high.

Summary
LZ 701 is composed of inorganic material, which can be used for high strength grouting material; The product is a powder compound grouting material. After mixing with water, it forms a kind of grouting material with shrinkage compensation and thixotropy. The compressive strength and fluidity can be adjusted by modifying the water-cement ratio during pulping. It is a composite product in environmental safety, strong environmental adaptability, early strength and late strength are high.
Features
● Shrinkage compensation: improve the anchoring effect, and continue to ensure that the anchor bolt is tightly fixed;
● Thixotropy: the slurry will not flow out of the orifice due to its own weight;
● Liquidity: adjustable flow time;
● Micro-structure compactness: effectively protect bolt/steel pipe from water or air corrosion;
● Early/late high strength: strength above 40MPa;
● Enough molding time: slurry has enough time to flow into the holes or pores;
● Process and equipment operation is simple, the force injection LZ 701 grouting material and water are added to the mixer according to a certain proportion, and the mixing is about 3-5 minutes. 25 kg of powder can be stirred at a time to produce a slurry of about 15 liters.
