[Product Introduction]
Huaqiansu is a special masterbatch for grouting materials. It has good cement adaptability, small dosage, easy to disperse, easy to store and transport, and realizes off-site manufacturing and on-site ready-to-use grouting materials. , which solves the transportation bottleneck problem in the popular application of grouting materials.
[Characteristics of grouting material]
b Early strength, high strength: natural compressive strength, natural compressive strength
b Micro expansion, no shrinkage after hardening: vertical expansion rate
b Large flow state, easy for grouting construction: Fluidity
bConstruction temperature: Can be constructed at temperatures above -℃.
[Use of grouting material]
b Secondary grouting of equipment foundation and filling of special spaces
b Anchorage of structural parts such as anchor bolts
b Increase and reinforcement of beam and column sections.
[Performance of grouting material]

[Instructions for mixing grouting materials]
The first step, mixing equipment:
According to the actual conditions of the construction site, determine the mixing equipment and the amount of mixing at one time. For example: the mixer can mix kilograms per jar.
The second step is to calculate the dosage:
Determine the strength level of the grouting material to be prepared, and calculate the dosage of cement, sand and water per tank according to the reference mix ratio in the table above. Taking strength grade and kilogram as an example, the mix ratio is as follows:
Strength grade of grouting material
Ordinary Portland cement
Medium and coarse sand
Mixture
Stone (grains Diameter -)

The third step is to add materials and mix:
After starting up, alternately mix the cement and sand into the mixer for initial mixing.
First, slowly add about /3 of the water into the blender while stirring, and stir for a few minutes until the mixture is evenly mixed. Then add the remaining /3 of the water into the blender at one time, and continue stirring for about - minutes until it becomes flowing. Ready to use in mortar form.
[Grouting Construction Instructions]
Pour the grouting material mixed with water into the area to be grouted at one time and continuously. No special machinery or vibration is required.
It is best to use up the grouting material mixed with water within hours.
After grouting is completed, the formwork can be removed after an hour,
and carried out in accordance with ordinary concrete construction and maintenance standards.
