What are the characteristics of grouting materials?

Grouting material is made of high strength material as aggregate, cement as binder, supplemented by high fluidity, micro-expansion and anti-segregation substances. Add a certain amount of water to the construction site and mix well before use. The grouting material has good fluidity, rapid hardening, early strength, high strength, no shrinkage and slight expansion; Non-toxic, harmless, non-aging, pollution-free to water quality and surrounding environment, good self-tightness, rust resistance and other characteristics. It has the advantages of reliable quality, low cost, short construction period and convenient construction and use. Fundamentally change the stress of the equipment base, so that it can bear all the load of the equipment evenly, thus meeting the installation requirements of various electromechanical equipment (heavy equipment high-precision grinder), and it is an ideal grouting material in the era of installing no shim.

Grouting characteristics

▲ After early strength and high strength pouring, the strength of 1-3 days is as high as 30Mpa, which shortens the construction period.

▲ At the site of gravity flow, just add water to stir and pour it directly into the equipment foundation. Mortar flows by itself, construction is vibration-free, and vibration-free long-distance grouting construction is guaranteed.

▲ Long-term use of micro-expansion casting will not cause shrinkage, which will ensure close contact between equipment and foundation, and will not cause shrinkage between foundations. Appropriate expansion compressive stress will ensure long-term safe operation of equipment.

▲ After soaking in engine oil for 30 days, the strength of the product is improved by more than 65,438+00%, and the molded product is compact, waterproof and environmentally friendly.

▲ The durability is 2 million fatigue tests, and the strength of 50 freeze-thaw environment tests has no obvious change.

▲ Good weather resistance-long-term safe use at 40℃ ~ 600℃.

▲ Resist low alkali corrosiveness and strictly control the alkali content of raw materials, which is suitable for projects that require inhibition of alkali-aggregate reaction.
