Scope of use
Cement is especially suitable for the manufacture of concrete, precast concrete, water concrete, GRC products, adhesives and other special occasions, widely used in colored road bricks, permeable bricks, cultural stone, sculpture crafts, terrazzo, wear-resistant floor, putty, etc., with high light line reflection performance, Make the roadside stone, road signs, road central divider have higher traffic safety performance.
Construction process:
Secondary grouting of equipment foundation:
(1) Before grout, the equipment bottom plate and concrete foundation surface in contact with the grout material should be cleaned up, and there should be no loose gravel, floating slurry, floating ash,
Oily, waxy, etc. 24h before grouting, the foundation concrete surface should be fully moistened
(2) When grouting twice, grouting should be carried out on one side until it spills out from the other side, and grouting should not be carried out from opposite sides at the same time. Once the grout starts,
It must be done continuously and the grouting time should be as short as possible.
(3) When the distance between the track foundation or grouting is long, it can be constructed in sections depending on the actual project situation, and the length of each section should not exceed 5 meters. If the base plate of the equipment has a complex structure, it is appropriate to use pressure grouting.
(4) It is strictly prohibited to vibrate during the grout process, and the grout booster can be used if necessary. The booster pushes the grout material along the bottom of the slurry flow direction, and it is strictly prohibited to push from the middle and upper part of the grout layer.
(5) After the grouting of the equipment foundation is completed, it is appropriate to cut 45° bevel Angle to the outsiders along the edge of the bottom plate after the initial setting of the grout material. If the cutting treatment cannot be carried out, the surface of the grout layer should be calended with a trowel after the initial setting.


Concrete structure renovation and reinforcement grouting:
(1) The concrete surface in contact with the cement-based grout material should be fully chiseled.
(2) To repair the defects of the concrete structure, the loose concrete should be removed and made
Expose the rebar and cut the edges of the repaired area into a vertical shape.
(3) All gravel, dust or other debris should be removed before grouting, and wet the base concrete surface.
(4) Pour evenly mixed grout into the template and hit the template appropriately.
(5) When the thickness of the grout layer is greater than 150mm, relevant measures should be taken to prevent temperature cracks.
