& The grouting material is formulated with high-strength materials as aggregates, cement as binding agent, and supplemented by high fluidity, micro-expansion, anti-segregation and other substances. It can be used after adding a certain amount of water at the construction site and stirring evenly.
It has the characteristics of good self-flowing properties, rapid hardening, early strength, high strength, no shrinkage, micro-expansion, non-toxic, harmless, no aging, no pollution to water quality and surrounding environment, good self-tightness, and anti-rust. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and easy use. Fundamentally change the stress situation of the equipment base so that it can evenly bear the entire load of the equipment, thus meeting the installation requirements of various mechanical and electrical equipment (heavy equipment high-precision grinders). It is an ideal grouting material in the era of padless installation.
Uses
Grouting materials are mainly used for: anchor bolt anchoring, emergency repair of aircraft runways, fixation of nuclear power equipment, reinforcement of road and bridge projects, machine bases, steel structures and foundation mouths, and secondary equipment foundations. Grouting, planting steel bars, concrete structure reinforcement and renovation, crack management of old concrete structures, mechanical and electrical equipment installation, track and steel structure installation, static pile sealing engineering, thickening of wall structures and repair of water leakage, various Collapse grouting of various foundation projects and various emergency repair projects.
Classification of grouting materials
Mainly used for: anchoring anchor bolts, cutting and burying steel bars, and secondary grouting of equipment foundations with grouting layer thickness &&d&. Secondary grouting of equipment foundations with oil-resistant requirements is called ordinary grouting material
. It is mainly used for: secondary grouting of equipment foundations with grouting layer thickness & Reinforcement and reinforcement of building beams, slabs, columns, foundations and floors (repair thickness &). Secondary grouting of equipment foundations with oil-resistant requirements is called special grouting material for reinforcement projects
Mainly used for: prestressed channel grouting, grouting layer thickness &&d& secondary grouting of equipment, concrete beam and column reinforcement of the gap between angle steel and concrete Grouting, called special grouting material for concrete gap repair
, mainly used for: precision, large-scale, complex equipment installation, reinforcement and reconstruction of concrete structures, reinforcement, rapid repair of pavement, called high-strength non-shrinkage grouting material
, mainly used for : Special grouting material for high-temperature environments. It has stable volume under high temperature and good thermal shock resistance. The equipment is exposed to high-temperature radiation temperature environment for a long time. The thickness of the grouting layer is &&d&; Used for: short construction time, hourly strength, equipment can be operated immediately, grouting layer thickness &&d& secondary grouting rush construction period project, special grouting material for emergency repair project
Mainly used for: large volume, high precision, complex structure The grouting needs of the equipment should be such that no dead corners are left in the grouting parts. It has good stability and is called the special grouting material for precision equipment and extra-large heavy industry equipment. It is called the special grouting material for precision equipment and extra-large heavy industry equipment
. It is mainly used for: rapid strength growth under negative temperatures, without being affected by freezing damage, and foundations. Bolt anchoring, buried steel bars, and secondary grouting of the equipment foundation with a thickness of grouting layer. The secondary grouting of equipment foundations with oil-resistant requirements is called anti-freeze grouting material
Features
▲ Early and high-strength pouring, the acquired strength can be as high as above, shortening the construction period.
▲In the self-flowing state, you only need to add water and stir on site, and pour it directly into the equipment foundation. The mortar flows by itself, and the construction is vibration-free, ensuring vibration-free and long-distance grouting construction.
▲ The micro-expansion cast body will not shrink after long-term use, ensuring close contact between the equipment and the foundation, no shrinkage between the foundation and the foundation, and appropriate expansion compressive stress to ensure the long-term safe operation of the equipment.
▲ Resistant to oil penetration. After soaking in engine oil for days, its strength increases by more than %. It is molded, dense, impermeable, and adapts to the oil pollution and environmental protection of the machine base.
▲ Durability tested 10,000 times by fatigue test, and the strength showed no significant change in the freeze-thaw environment test.
▲ Good weather resistance, long-term safe use at ℃ ~ ℃
▲ Low alkali corrosion resistance Strictly control the alkali content of raw materials, suitable for projects that require inhibition of alkali aggregate reactions.
