High-strength non-shrinkage grouting material
Contact number
High-strength non-shrinkage grouting material is a cement-based self-flowing micro-expansion dry mortar with early strength, high-strength self-flowing and micro-expansion characteristics, and is suitable for equipment foundations Reinforcement and transformation of secondary grouting concrete structures and anchoring of anchor bolts and other projects.
Product features of high-strength non-shrinkage grouting material: early strength and high strength. The compressive strength can reach above 1 hour after grouting. The bolts can be tightened and the machine can be started for testing. The highest day intensity can reach above. It has high self-flowing properties and can be used by adding water and stirring on site to fill all gaps without vibrating. There is no shrinkage after micro-expansive grouting to ensure close contact between equipment bolts and foundation. Winter construction performance is the lowest and outdoor construction is allowed at low temperatures. Durability: This product is an inorganic cementing material with a service life greater than that of the base concrete. It has undergone tens of thousands of fatigue tests and freeze-thaw cycles with no significant change in strength. Resistant to oil penetration and high temperature impact. After being immersed in engine oil, the strength is higher than before being immersed in oil. Flame cutting and welding of steel bars are allowed after the reinforcement is planted. Scope of application of high-strength non-shrink grouting material
Universal reinforcement
Grouting thickness Equipment foundation Secondary grouting Anchor bolt anchoring and embedded steel reinforcement Reinforcement and reinforcement of building beams, slabs, columns, foundations and floors.
Pisolite reinforced type
Contains ~ large aggregate, suitable for secondary grouting of equipment foundation with grouting layer thickness and grouting length. Reinforcement of the building's beam-slab-column foundation and floor.
Ultra-fine reinforced type
Ultra-fine aggregate is suitable for secondary grouting of equipment foundations and steel structure column footings with a grouting layer thickness. The gaps between the concrete beams and columns reinforced angle steel and the concrete are grouted.
Super early strength reinforcement type
The hourly strength reaches 100,000. It is suitable for rapid repair of cement concrete pavements such as railway sleepers, airport runways, etc., rapid repair of water sealing and leakage, and rapid repair of leaks.
The technical indicators of high-strength non-shrinkage grouting material conform to the standard/standard specifications and the standard maintenance test block size
Introduction to high-strength non-shrinkage grouting material High-strength non-shrinkage grouting material is a cement-based self-flowing micro-expansion dry mortar with early strength and high strength The characteristics of self-flow and micro-expansion are suitable for the reinforcement and reconstruction of secondary grouting concrete structures of equipment foundations and the anchoring of anchor bolts.
Instructions for grouting construction of high-strength non-shrink grouting material
One foundation treatment
The surface of the foundation should be roughened. Clean the surface of the foundation. There should be no gravel, floating slurry, ash, oil, dirt, release agent and other debris. The surface of the foundation should be fully moistened 1 hour before grouting and any accumulated water should be removed 1 hour before grouting.
The second formwork shall be supported according to the grouting construction drawing. The joints between the formwork and the basic formwork should be sealed with cement slurry tape to ensure that the entire formwork does not leak.
The horizontal distance between the formwork and the equipment base should be controlled to the left and right to facilitate grouting construction. The top elevation of the formwork should be higher than the upper surface of the equipment base. If grouting occurs during grouting, it should be dealt with promptly. High-strength non-shrinkage grouting material Three grouting materials are prepared. Generally, add water and stir according to the standards for the general reinforced type. Add water and stir according to the standards for the pisolite reinforced type.
The mixing of high-strength non-shrinkage grouting materials can be done mechanically or manually. It is recommended to use a forced mixer for mechanical mixing to ensure sufficient and even mixing for 2 minutes. Manual mixing time is completed within minutes. The fluidity of the mixed grouting material decreases as the parking time increases and should be used up within minutes. It is strictly prohibited to mix any additives into high-strength non-shrinkage grouting materials.
Four grouting construction methods of high-strength non-shrinkage grouting material
Longer equipment or track foundations should be constructed in sections.
After the grouting starts, it must be carried out continuously without interruption and the grouting time should be shortened as much as possible.
Five maintenance steps for high-strength non-shrink grouting material
After grouting is completed, the grouting material should be immediately covered with a straw bag or rock wool quilt and kept moist after initial setting.
The grouting material mixing water and maintenance measures during winter construction should comply with the relevant provisions of the current construction quality acceptance specifications for concrete structure projects.
Do not subject to vibration for hours after grouting to avoid damaging the unhardened grouting layer.
High-strength non-shrink grouting material packaging, storage and transportation packaging specifications/bags should be stored in a ventilated and dry place and protected from direct sunlight. The shelf life is one month. If it exceeds the shelf life, it should be re-inspected before it can be used.
