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: Bathroom wall brush flexible waterproof, stick wall bricks easy to fall off after it? Is not tiling cement to add 901
- Not necessarily, this specific situation you need according to the nature of your waterproof paint at that time to decide your next construction material. If you are not very understanding of this line, it is recommended that you information professional construction workers, workers long-term exposure to a variety of waterproof materials, the material properties of which is relatively more than the Shanghai high-crossing fishing for more familiar with each other. So, the information field workers will be better.

- Q: Do the wall waterproofing can be directly on the brick brush on a layer of waterproof material on it
- Can be ah, but in general are rafting spoiled slander diarrhea oblique riveting is done on the concrete, in fact, there are some tiles waterproof role, the late seepage of the words will be outside the brush waterproof paint, are generally used transparent glue, recommended Dragon wall waterproof transparent plastic, before the seepage used to the past few years will not change color, does not affect the decorative effect.
- Q: 1: 8 cement ceramic particles to find how to set the amount of slope set
- 1: 8 cement ceramic particles to find slope layer, according to the amount of 1: 8 cement vermiculite with the amount of vermiculite in the calculation (that is, each cubic 1: 8 cement ceramsite, cement 0.175t, ceramic 1.02 cubic). 1: 8 cement ceramsite to find slope layer cover roof insulation layer quota, and then adjust the material spread, or the preparation of supplementary quotas. The quota is a standard that sets the amount of resources consumed by a unit of qualified products in a reasonable manner and rational use of materials and machinery. It reflects the level of social productivity in a given period. For each construction project, the amount of labor is measured, including basic and other labor. Plus the material of this project, including basic materials and other materials. For the labor unit price, is based on the local labor value of different types of work, the value of the material is based on the pre-market price to develop the budget price.
- Q: External wall insulation with anti - cracking mortar but also with waterproof mortar Are the two materials the same? Only one okay?
- The use of the two materials is similar, but not used in a position, different products used in different locations, rather than 2 election 1.--------- on the external wall insulation, the national standard requirements and construction Norms do not mention the term water mortar, it is clear that the waterproof mortar is designed to do waterproof with, can not do with insulation. In addition, although the anti-cracking mortar with a certain degree of waterproof capacity can not be used as a waterproof mortar, the same, although the waterproof mortar waterproof, but do not have the external wall ridicule rafts Wo Bogao boudoir sound card requirements of other indicators.
- Q: [Single choice] the following materials, do not belong to the commonly used building mortar cementing material is (). [Two construction division "construction] A. Lime B. cement C. fly ash D. gypsum
- For a certain field of practical experience of the candidates, this problem is not difficult
- Q: Why brick-based project man-made masonry mortar can not modify the market price
- Masonry mortar itself is a composite material, the price adjustment should be determined by the number of its constituent materials, unit price adjustment, can not be directly adjusted, that is, by adjusting the cement, water, lime, sand and the unit price to adjust the price of mortar
