Detailed Product Description: | High-strength non-shrink grout consultation: 18690497786 with special cement as a binder, selected high-strength materials as aggregate, combined with high flow, micro-expansion, anti-segregation and other substances in the preparation. The product has a good gravity, rapid hardening, early strength, high strength, no shrinkage, micro-expansion; non-toxic, harmless, non-aging, pollution of water quality and the surrounding environment, since the density is good, rust and other characteristics. During the construction has reliable quality, reduce costs, shorten the construction period, and ease of use. Fundamentally change the force equipment base, so that uniform to bear all the load equipment to meet a variety of mechanical and electrical equipment (heavy equipment precision grinding machines) installation requirements, is no ideal age pad installed grout. "Adams Wenger" brand ordinary type grouting material mainly used for: anchor bolts, plant buried rebar, grouting thickness 30mm <δ <200mm base secondary grouting equipment. There are anti-oil based secondary grouting equipment required. I. Features ▲ early strength strength of up to 1-3 days after pouring more than 30Mpa, shorten the construction period. ▲ artesian state scene just add water and stir, pour directly equipment foundation, mortar gravity, vibration-free construction to ensure that no vibration, long-distance grouting. ▲ micro-expansion casting body long-term use of non-shrink, equipment and infrastructure to ensure close contact between the foundation and the basis of no shrinkage and expansion stress to ensure proper long-term safe operation of equipment. ▲ resistant to oil seepage in the oil for 30 days increased by 10% or more of its strength, molded, dense, impervious to adapt to the base oil and environmental protection. ▲ durability 2,000,000 times fatigue test, 50 freeze-thaw was no significant change in environmental testing. ▲ weather resistance -40 ℃ ~ 600 ℃ long-term safe use ▲ strict control of raw materials, low alkali content of alkali corrosion, suitable for alkali - aggregate reaction inhibit the requirements of the project. Second, the product Physical Model compressive strength (MPa) vertical expansion (%) Fluidity (mm) slump (mm) water feed ratio (%) Common type 2 hours 1 day 3 days 28 days / ≥ 22 ~ 27 ≥ 38 ~ 45 ≥ 70 ≥ 0.02 300 ~ 380/13% ~ 15% three, use Method 1. Surface cleaning equipment foundation foundation treatment, no gravel, laitance, dust, grease and mold release agents and other debris. Before grouting 24h, equipment foundation surface should be sufficiently moist. Before grouting 1h, should suck water. 2. Grouting under way to determine the actual situation of the equipment base, select the appropriate grouting, because CGM has good flow properties, under normal circumstances, use the "weight method grout" can be, coming directly from the template slurry poured into the mouth, completely rely on self-leveling slurry weight and fill the entire perfusion space; perfusion area if large structures are particularly complex or a small space and very far away, we can use "high funnel filling" or "pressure grouting method" grouting to ensure that the slurry can fully fill every corner. 3. Formwork according to the determined way and grout grouting construction drawings branch set up a template, the template positioning equipment base elevation above the upper surface should be at least 50mm, template must support set tight, secure, prevent loosening, leakage of plasma. 4. Mixing grout on the certificate by product recommended ratio of water to determine the amount of water, mixing water should be drinking water, water temperature 5 ~ 40 ℃ is appropriate, can be mechanical or manual agitation. Mechanical stirring, the stirring time is generally 1 to 2 minutes. When using manual mixing, advised add 2/3 of the water for 2 minutes, after adding the remaining water stirring is continued until a uniform, standard consistency water content of 12% -14%. 5. Grouting Grouting should meet the following requirements: (a) from the side of the slurry poured until it overflows the other side in order to facilitate the discharge device between the base and the concrete foundation of the air, so that grout, not from the four sides grouting. (2) after the start of grout must be continuous, without interruption, and filling time should be as short as possible. (3) should not be vibrated during the grouting process, if necessary, can be driven diversion bamboo strips. (4) Each grouting thickness should not exceed 100mm. (5) a long track-based equipment or grout should be segmented construction. Each length of 10m is appropriate. (6) found during grouting surface bleeding phenomenon can be a small amount of CGM dry material dispenser, dry water. (7) on the grout layer thickness is greater than 1000mm bulky equipment foundation grouting, grouting material in the mixing ratio of 1:1 by total when adding 0.5mm stones, but subject to testing to determine whether it can be irrigated can meet the requirements. (8) Equipment foundation grouting is completed, the part should be removed before the final setting grout layer for processing. (9) in the grouting process until the release, you should avoid filling layer is subjected to vibration and impact, so as not to damage the outstanding hard grout layer. (10) Template horizontal distance from the base of the device should be controlled at about 100mm facilitate grouting. (11) Grouting plasma phenomena, such as running, should be timely treatment. (12) When a large amount of equipment foundation grouting, mechanical mixing method should be used to ensure the grouting. 6, the conservation (1) within 30 minutes after grouting, curing compound immediately or cover and affix the plastic film such as rockwool for conservation, or immediately after the final setting of the grout layer watering moisture conservation. (2) winter construction, conservation measures should also comply with the current "reinforced concrete construction and acceptance norms" (GB50204) the relevant provisions. |
