Four, product characteristics
"Pour 1-3 days after high early strength was as high as 30Mpa, shorten the construction period.
Since the flow field - just add water, stir, direct filling equipment foundation, mortar self construction, free vibration, ensure the grouting construction of long distance without vibration.
Casting body is used for a long time without shrinkage / micro expansion, to ensure that equipment and basic close contact, no shrinkage between the foundation and foundation, and appropriate expansion of the compressive stress to ensure the long-term safe operation of equipment.
* anti oil leakage after 30 days soaking its strength in the oil increased by more than 10%, molding, compacting, impermeability, adapt to the base oil of environmental protection. * durability 2000000 times fatigue test, 50 times freeze-thaw environment test strength has no obvious change.
"Good weather -40 to 600 DEG C is safe for long-term use
* low alkali corrosion resistance of the strict control of raw material of alkali content, suitable for alkali aggregate reaction inhibiting requirements engineering.
Five, the use of methods
1 Foundation Treatment
Cleaning equipment based on the surface, there shall be no stone, laitance, dust, dirt and other debris demoulding agent. Before grouting 24h, fully moisten the surface of equipment foundation. Before grouting 1H, should be sucked up water.
2 determine the grouting method
According to the actual situation of equipment base, selection of grouting method of corresponding flow, because of its good performance, in general, with "weight grouting" can, will paste directly from template export poured into slurry, completely rely on the self weight to leveling and filling the whole filling space; if a large area, especially the complex structure of perfusion or a very small space and distance, can use "high funnel method grouting" or "pressure grouting, grouting method" to ensure that the slurry can be fully filled every corner.
3 formwork
According to the grouting and grouting construction diagram determined by the way of support design templates, template location elevation should be higher than the equipment on the base surface of at least 50mm, template must support of a tight, firm, to prevent loosening, leakage.
The 4 stirring grouting material
According to the water feed products recommended certificate than the amount of water, mixing water should be used to drinking water, the water temperature to 5 ~ 40 degrees is appropriate, can use mechanical or manual stirring. By mechanical mixing, stirring time is generally 1 to 2 minutes. The use of artificial mixing, should first join 2/3 with water and stir for 2 minutes, then add the remaining water to continue to stir until evenly, standard consistency water volume is 12%-14%.
5 grouting
Grouting construction should meet the following requirements:
(1). The slurry should be poured into the side, until the other side overflow until, in order to facilitate the discharge between the device frame and concrete foundation of air, so that the filling, not from the four sides of the grouting.
(2). The grouting after the start, must be continuous, not interrupted, and should be possible to shorten the filling time.
(3). During the grouting process should not be vibrated, when necessary, available bamboo laths were pulling the diversion.
(4). Each filling layer thickness should not exceed 100mm.
(5). The grouting long equipment or track foundation, should use the segmental construction. The length of each section is appropriate in 10m.
(6). The grouting process such as the discovery of surface bleeding phenomenon, can dispenser a small amount of dry material, sucking up water.
(7) for the foundation of equipment grouting layer thickness is greater than 1000mm in large volume, stirring grouting material according to total ratio 1:1 join 0.5mm stones, but the required test for determining the groutability can not meet the requirement.
(8). The equipment foundation grouting is completed, should be removed part shall be treated in the grouting layer before the final setting.
(9). In the grouting construction process should be avoided until the mold, filling layer by vibration and collision, so as not to damage the pending grouting hard layer.
(10) the horizontal distance between the template and the equipment of the base should be controlled at around 100mm, in order to facilitate the grouting construction.
(11) slurry filling in phenomena such as appearance, should be timely treatment.
(12) when the equipment foundation grouting amount is larger, should adopt mechanical agitation mode, in order to ensure grouting construction.
6, maintenance
(1) after grouting is finished. In 30 minutes, immediately spray curing agent or covered with plastic film and affix rockwool were maintenance, or in the grouting layer after the final set immediately sprinkler wet maintenance.
(2) in winter construction, conservation measures shall be in accordance with the "reinforced concrete construction acceptance norms" (GB50204) the relevant provisions.
(3) at different temperature curing time and removal time schedule
Daily minimum temperature (c) time of stripping (H) curing time (d)

- Q: What is good for roof waterproofing? Coil or waterproof paint ah?
- Roof waterproofing can not use a single waterproof material, must be rigid and flexible combination of construction 1. The first layer of flexible waterproof, such as waterproof coating. 2. The second time to do mortar waterproof, as a copy of the Dan Dan light chi chi corpse built a layer of protective layer. Flexible waterproof tensile elongation, a little bit of settlement or deformation will not damage the waterproof layer. Rigid waterproof (ie mortar waterproofing agent) waterproof at the same time, can play a protective role, waterproof layer is not easy to be destroyed. If the roof area is not particularly large, it is recommended to use waterproof coating (must choose flexible), good waterproof coating waterproof life than the long, and some environmental protection. Above do mortar waterproof as a protection. If you want to buy the coil, then, in particular, pay attention to the market a lot of waste plastic is made, the water cycle is even shorter. , Note: Be sure to buy regular manufacturers of regular products. And to standard construction.
- Q: What waterproof material can be combined with cement mortar to play a waterproof effect?

- Q: How to install squatting pan? Need to pay attention to what matters?
- Patented safety squatting pan installation height with a trap within 250MM.
- Q: What is the usual leveling of the ground? By which type of work to complete?
- The ground of the kitchen and the bathroom needs to be leveled, as it relates to the need for subsequent flattening tiles and slopes of water, which is done by the mason. If it is the floor, then it is involved in what you use the floor? If it is solid wood flooring that will use the wood keel, wood keel spacing is based on the length of the floor to set, the general spacing is one-third of the floor. This work is done by carpentry or people who sell the floor. Specifically who does it depends on you. Leveling the standard is actually looking for a horizontal line. If it is a composite floor, it depends on your room how the ground flatness. If the problem is not big, it can be laid directly on the ground, (solid wood flooring below is sure to play wooden keel), but under the floor of the moisture pad is certainly not less. If the flatness of the room is not enough, then it needs leveling, leveling the material can be "self-leveling." It is a kind of cement mortar like glue-like objects, poured on the ground will flow to the various corners of the room to make the role of the ground level, dry after the ground on the flat. There is also a way to play in the composite floor under the wooden keel leveling, after playing wood keel but also covered with blockboard. But this is more expensive than "self-leveling". Leveling the standard is actually looking for a horizontal line.
- Q: I am referring to the amount of dry mortar that is not stirred
- 7 kg benzene board, scientific name is called (double-sided) steel mesh polystyrene board, both building materials and decorative materials, generally used for partition
- Q: Choose epoxy mortar floor, looking for epoxy mortar floor construction program
- Epoxy mortar floor, widely used in machinery, electronics, chemicals, medicine, tobacco, textile, furniture, light industry and other manufacturing plants and warehouse floor, its ultra-high strength, wear resistance, beautiful and durable, Texture, solid, easy maintenance, etc
