By-40 BY-60 BY-80 BY-90 series grouting materials are widely used in the grouting of factory buildings, mechanical equipment, electrical equipment installation projects, overhaul and emergency repair projects, port and dock track installation projects, as well as the reinforcement of various concrete structures, waterproofing and road repair.
I. Product Features
1, good fluidity: no bleeding, self-leveling effect, can fill all gaps.
2. Early strength and high strength: the compressive strength can reach 30% of the final strength in 24 hours and more than 60% in 3 days. Install the equipment within 1-3 days.
3, no shrinkage, high bonding strength: slightly expanded, and good grip with steel bars. Ensure that the anchor bolt is firmly combined with the foundation (steel structure) foundation and new and old concrete.
4. Good durability: it belongs to silicate inorganic castable, which is non-aging, non-corrosive to steel bars and oil stain resistant. Third, the method of use
Preparation: Clean the surface, and there shall be no debris such as gravel, laitance and oil stain. 24 hours before grouting, the surface should be fully wet. There shall be no water before grouting.
Formwork support: the formwork shall not leak slurry, and the top of the formwork shall be about 50mm higher than the upper surface of grouting.
Stirring: add a certain amount of water into the mixing barrel, and then pour the materials into the barrel for stirring. From the beginning of feeding to the end of stirring, the stirring time should be controlled at about 3-5 minutes. In the process of mixing, the blades should not rise above the mud level to avoid bringing in air.
Pouring: grout from one side to overflow from the other side, and tamp with bamboo pieces if necessary.
Maintenance: 3-5 hours after grouting, the surface of grouting layer should be polished smooth, and then covered with wet cloth or straw bag for water conservation. The water curing time shall be no less than 7 days, and the watering times shall be subject to keeping the grouting material in a wet state.
Four. Packaging and storage
Moisture-proof packaging, net weight of 25kg/ bag, shelf life of 6 months; Must be stored in a dry and ventilated room, pay attention to moisture, please use it as soon as possible.
Scope of use:
1. Anchor bolts for large equipment and precision equipment.
2. Pouring of steel structures (such as tracks, steel frames and steel columns). ) fixed on the foundation.
3. Post-tensioned prestressed reinforcement grouting.
4. Beam and column reinforcement.
5. Construction joints of subway, tunnel and underground engineering shall be embedded by reverse method.
6. Wall structure thickening and leakage repair.

Antique glazed tile
It is suitable for new sloping roofs of concrete structures, steel structures, wood structures, brick-wood mixed structures and flat sloping roofs of old buildings, with a slope of 15-90 degrees and a temperature of -40℃-70℃.
The second new building material: light dry-hung external wall thermal insulation decorative hanging board
The system adopts dry hanging installation technology, and uses rivets to organically connect the thermal insulation and decorative composite board with the external wall of the building, thus completing the thermal insulation, decoration and waterproof functions of the external wall at one time. The self-weight of the system is 4-5 kg/m2, which is suitable for all kinds of new and rebuilt exterior wall thermal insulation and decoration projects. Book plastering system will not appear paint cracking, tile falling off and other phenomena.
Characteristics of light dry-hung external wall thermal insulation system;
First, it is suitable for all kinds of grassroots walls.
Second, it does not crack or fall off, which is efficient and energy-saving, and the system life is long.
Third, the installation is convenient and the construction is not affected by the climate.
Fourth, the decorative appearance is diverse to meet different architectural styles.
5. It has unique functions of heat preservation, decoration and waterproof.
Six, permanently solve the problem of water leakage at the joint between the door window frame and the wall.
Seven, the system has the best cost performance.
The third new building material: the substitute product of color steel plate
Upvc corrugated tile
-patented structure of UPVC three-layer composite core foam
-Anti-corrosion tiles for roofs of industrial buildings
-Substitute products of colored steel shingles, noise-deadening and heat-insulating, acid and alkali-resistant roof shingles.
-The tile is super tough, and the nail opening does not need any treatment, so it will not corrode and leak rain.
