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

- Q: Now commonly used cement mortar building, what is the ancient use of clay material it
- Glutinous rice and lime, (sometimes with eggs), or glutinous rice and yellow mud.
- Q: Inorganic active wall insulation materials and building insulation mortar What is the difference
- Product testing standards are based on the same national standard for testing only the product composition and construction of different effects are also different
- Q: Is it possible to protect the waterproof layer of fine concrete? Is the mortar protective layer applied directly to the linoleum? Like the rough sand will Ge broken linoleum it? And mortar layer thickness strength is not large, can play a protective role? In fact, do not understand what the protective layer to protect, is the roof of the people, set the load crushed waterproof layer? Rigid waterproof layer I do not know what to protect. More
- Flexible waterproof layer of the protective layer there are two: flexible protection and rigid protection, flexible protection is a layer of cement on the coil, rigid protection is coated with a layer of 2CM thick cement mortar, but these are for SBC120 coil Germany, SBS is no protective layer, SBS above the cement can not be wiped. Flexible waterproof layer: the use of a certain flexibility and greater elongation of the waterproof material, such as waterproofing membrane, organic waterproof coating composition of the waterproof layer. Building waterproofing works in the building waterproof waterproof waterproof. Rigid waterproof layer: the use of high strength and no extension of waterproof materials, such as waterproof mortar, waterproof concrete formed by the waterproof layer. It is called rigid waterproofing by relying on the compactness of the structural members themselves or using rigid materials for waterproofing layers to achieve the purpose of building waterproofing.
- 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: 1: 8 cement ceramic particles to find how to set the amount of slope set
- Roof 1: 8 cement ceramsite to find slope layer: It is recommended to use energy-saving quota in the cement perlite roof insulation quota, and then the inside of the perlite into ceramic bar. The gray mortar is used as the leveling layer of cement mortar, and then the material is replaced with lime mortar. According to the design should have cement, ceramic ratio, I think we should prepare a supplementary quota. To discuss a thermal rating, and then adjust the material prices. With C10 ceramsite concrete should be able to, a cubic ceramic, plus 260KG cement, plus 0.34 sand rate, you can.
- Q: What is the ratio of the various materials in the C25 concrete to the size of the material? The director did not do the building management, say what to estimate the number of sand, stone, cement, I want to get out of this ratio to count, I quickly fainted. I know that one side of the concrete to use about 2.5T cement, but the proportion of gravel and do not know, I can only tell the boss how many kilograms, how many tons forget. Please know how to teach me, it is best to tell me how to count. Question added: I would like to know how much the volume is, the weight is better than I have. 325 # Ordinary Portland Cement more
- Construction with the ratio: Cement: 301 kg (425 # ordinary Portland cement) Sand: 655 kg (in sand) Stone: 1305 kg (5 ~ 40mm gravel) Water 粻 Shan Gang catch the non-stone stem will: 149 Kg The use of the environment for the dry office room slump requirements of 35 ~ 50mm
- Q: What are the general types of waterproof materials, the number of years of use?
- Waterproof material in general, sub-coating and coil two categories, but also points to rigid materials and flexible materials, the key depends on what you do
- Q: Polystyrene insulation mortar insulation in the external walls. Foreground will be how,
- According to the provisions of the document No. 65: civil building insulation materials used to ridicule the tank waste Intuit Biao Shizha sound burning performance for the A-class material. Polystyrene insulation mortar market prospects are not very optimistic.
- Q: Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
- Under normal circumstances need to use with the insulation materials
- Q: Do you install firewood in the door frame when installing the fire door? There is nothing related to the helium trace grams of grams of long-haun glory magic norms clearly can not or can. What is the specification number? (03j609 Atlas shows C20 cement mortar) Thank you more
- If there is no local norms, issued a separate request, then refer to the national standard atlas "fire doors and windows" to carry out; . the door frame to be filled with non-combustible materials, see note; . 30 album, filler C20 concrete
