Grout is a high-strength material, and grout can also be used as aggregate. Because most of the grout is the use of binding agent, and the characteristics of grout is also very special, such as grout it has a very good sealing, but also anti-rust, but also very environmentally friendly, then the next small talk to you have knowledge about grout. Introduce a few grout manufacturers.
How much is a ton of grout
Shandong Luming new materials production of metal fiber super high: ￥ 102 / ton
Xi'an Deming? The ordinary type? Early strength? High-strength: ￥ 103 / ton
Zhengde high-strength non-shrinkage grout: ￥ 800 / ton
Hebei high-strength non-shrinkage grout: ￥ 700 / ton
Jinan, Shandong Province, high-strength non-shrinkage grout: ￥ 800 / ton

Grout Manufacturers
1, Xi'an Deming Metallurgical Building Materials Co., Ltd. is mainly engaged in the research and development of cement grinding aids, high-strength industrial building materials, advanced new type of unshaped refractory materials and additives. The products are widely used in many fields such as chemical industry, metallurgy industry, building materials, machinery industry, electronics industry, electric power, coal, environmental protection, etc. Some of the products are exported to Europe and Southeast Asia.
2, Fuzhou Zhengde Building Materials Technology Co., Ltd. is located in the beautiful banyan city of Fuzhou, is a modern building materials enterprise focusing on the research and development, production, sales and service of special building materials, the company adheres to the "right way to set up a base, the world of virtues" concept of survival and development of enterprises, in line with the "quality of survival, innovation and development, and the quality of the company, the company is committed to the development of the company. The company adheres to the "right way of life, virtue in the world" concept of corporate survival and development, in line with the "quality of survival, innovation and development, reputation to win the market" business philosophy, is committed to creating a leading new building materials enterprises
3, Cangzhou Hao Teng Building Materials Co. The business scope is widely involved in civil construction, anticorrosion insulation, roads and bridges, industrial plants and other structural transformation of the repair, structural reinforcement, concrete repair, equipment foundation grouting, steel anchoring, waterproofing and leakage, crack treatment, interface treatment, corrosion treatment, wall insulation, as well as a variety of decorative decoration engineering field.
Characteristics of grout
Early high strength, 1-3 days after pouring strength up to 30Mpa or more, shorten the construction period.
Self-flowing state, on-site only need to add water to mix, directly into the equipment foundation, mortar self-flowing, construction without vibration, to ensure vibration-free, long-distance grouting construction.
Micro-expansion, long-term use of the casting body without contraction, to ensure close contact between the equipment and the foundation, the foundation and the foundation without contraction, to meet the requirements of the second grouting of equipment, and appropriate expansion of compressive stress to ensure the safe operation of equipment for a long time.
Oil seepage resistance, its strength increased by more than 10% after 30 days of immersion in machine oil, molding body, dense, seepage resistance, adapt to the machine base oil pollution environmental protection.
Durability, 30 times fatigue test, 50 times freezing and thawing environment test strength without significant change.
Good weather resistance, -40 ℃ ~ 600 ℃ long-term safe use.
Low alkali corrosion resistance, strict control of the alkali content of raw materials, suitable for alkali - aggregate reaction with inhibition requirements of the project.
Grout use
1.? Foundation treatment
Sweep the surface of the equipment foundation, there shall be no debris, floating slurry, dust, oil and mold release agent and other debris. 24h before grouting, the surface of the equipment foundation should be fully wet. 1h before grouting, the water should be sucked dry.
2.? Determine the grouting method
According to the actual situation of the equipment chassis, select the appropriate grouting method, due to the CGM has a very good fluidity, in general, with the "self-weight method of grouting" can be, that is, the grout directly from the template mouth into the grout, relying solely on the self-weight of the grout itself to flow and fill the entire space of the grouting; if the area of the grouting is very large, the structure is particularly complex or the space is very small and the distance is very far away, you can use the "high funnel". The use of "high funnel method of grouting" or "pressure method of grouting" for grouting, to ensure that the slurry can fully fill all corners.
3. Support mold
Support the template according to determine the grouting method and grouting construction drawings, template positioning elevation should be higher than the upper surface of the base of the equipment at least 50mm, the template must be tightly supported, stable, in order to prevent loose, leakage of grout.
4. Grout mixing
According to the certificate of conformity of the product recommended water ratio to determine the amount of water, mixing water should be used for drinking water, water temperature of 5 ~ 40 ℃ is appropriate, can be used mechanically or manually stirred. Mechanical mixing, mixing time is generally 1 to 2 minutes. When using manual mixing, it is appropriate to add 2/3 of the water mixing for 2 minutes, and then add the remaining amount of water to continue mixing until uniform.
Grout in our life is a very common thing, it is mainly made of cement, so the grout has a very good hard performance, the general grout has a hard, fast hard, fast drying, no shrinkage, nor expansion of the performance, and grout also has a very good environmental performance, so many friends are like to use grout. The grout is also very convenient in the construction of the time, without spending a lot of time to monitor, and the cost of construction is also very low, and the cycle of installation is also relatively short, so the grout is more and more recognized in our lives.
