Jincheng track cement * * * price ***Non shrinking track cement * * * Non shrinking track cement is a * * * non shrinking grouting material developed by our company, which has the advantages of large fluidity, long operation time, high strength, and has been successfully applied to various track installation projects such as cranes and traveling cranes. At the same time, the material also has the characteristics of low temperature and early strength (winter construction type), which can be applied to track installation in winter low temperature environment. Product use: · Grouting of crane rail groove in port and wharf. (Track pressing plate grouting, base plate Bolt Fixed, etc.) · Primary and secondary grouting of various mechanical and electrical equipment (heavy equipment, high-precision grinder)· Steel structure installation works· Reinforcement of civil buildings· Grouting and fixing of column base, pile foundation and rock foundation· Seepage prevention and leakage prevention works. 1、 Main features: 1. The ordinary type can meet the requirements for normal use of the track after one day of construction. 2. The early strength type has a 2h compressive strength greater than 20MPa, meeting the requirements for rapid installation of the track. 3. The fluidity is large, no segregation, no bleeding, and the construction is simple to ensure the construction quality. 4. The water consumption range is wide, and the appropriate fluidity can be obtained by adjusting the mixing water consumption. 5. The fluidity loss is small, and the operation time is long Performance index: performance model setting time min fluidity (mm) strength (MPa) elastic modulus free expansion rate (%) other Bending and compression resistance GD-1 Initial setting, final setting, initial 30min, 24h, 24h, 28h, 28d, 28d, 28d, no bleeding, no corrosion to reinforcement,>30 ＜ 90 325 265 ＞ 10.0 ≥ 25 ≥ 60 ≥ 95 34GPa 0.08, construction method 1 Track * * * mastic shall be stored in a dry and cool place to avoid sun and rain; 2. Remove the oil stain cement Laitance and other impurities; 3. Before construction, wash the foundation surface with high-pressure water gun or q ì gun, fully wet the concrete surface with water 24 hours before construction, and remove residual water before grouting; 4. During construction, add water for mixing according to the recommended water consumption, and reduce the water consumption under the condition of meeting the fluidity. Generally, track cement is mechanically mixed. It is advisable to use up the amount of mixing within 30 minutes at a time. No more water can be added during the second mixing, otherwise the strength of track cement will be reduced; 5. Grouting shall be carried out continuously from one side of the track until the other side overflows and fills up without interruption, and the grouting time shall be shortened as far as possible. The operation must be continuous from the beginning of mixing to the end of grouting. If the track is long, it can be constructed in sections; 6. Curing shall be started immediately after grouting, and straw bags or plastic film And spray water regularly. In case of plastic film curing, it is necessary to uncover the film and spray water onto the track plaster surface; 7. Please consult our technical personnel for detailed construction methods related to maintenance, inspection and other severe weather conditions. The mass of each package of track glue for packaging, storage and transportation is 50kg ± 0.5kg, and it is packed in three-layer plastic woven bags. Storage and transportation: dry and cool. From the date of production, the storage period is six months without moisture. It shall be rechecked after expiration and can be used only after being qualified. The overview of track cement is made of cementitious materials, mineral admixtures, high-performance additives, etc. through factory production. Add water, stir and pour it evenly into the bolt hole and under the track to evenly transfer the load and bear the various forces of the upper part, which can improve the durability, shorten the construction period and reduce pollution in ports, docks and high-speed * * *. Jincheng track cement * * * price 1、 Product feature 1. Early strength * * *: the strength in one day can reach more than 20MPa. 2. Large flow gauge: the fluidity can reach 200-300mm, which can fill all the gaps and meet the requirements of secondary grouting. 3. No shrinkage: ensure close connection between equipment and foundation. 4. Low temperature workability: outdoor construction is allowed at minus 10 ℃. 5. Good insulation: high density structure, good impermeability and insulation after curing. 6. Strong durability: this product is an inorganic cementing material, and its service life is longer than that of the foundation concrete. After millions of fatigue tests, the strength of 50 freeze-thaw cycles has no obvious change. The strength has no obvious change after immersion in engine oil for 30 days 2、 Application method (I) Foundation treatment and formwork erection: 1. Roughen the concrete foundation surface and clean it. The components (such as steel backing plate) bonded with the base slurry shall be cleaned of rust and oil stains. 2. The concrete foundation surface shall be wetted 4~24 hours before pouring the base slurry, and there shall be no ponding during pouring. 3. The baffle shall be set tightly to prevent slurry leakage. （2） Grouting: 1. Amount of water added: add 7kg water to each bag (50kg) for mixing. If * * * mobility is not required for construction, reduce the amount of water used accordingly. 2. Mixing procedure: add the specified amount of water into the mixing bucket, put it into the mixer, pour some dry materials into the bucket for mixing, and then pour the surplus materials into the mixing. The time from the beginning to the end should be controlled within 3-5 minutes. 3. During mixing, the blades shall move slowly up, down, left and right along the periphery of the barrel to mix the dry materials adhered to the bottom and wall of the barrel; The mixing blade shall not be lifted above the liquid level of the base slurry to prevent air from entering the base slurry. 4. When pouring, inject from one side as far as possible to drain the air between the bottom plate and the concrete foundation. If necessary, bamboo pieces and other tools can be used for diversion. The pouring must be carried out continuously without interruption. （3） Curing: 1. Cover the poured bed slurry with wet straw bags or cloth, and spray water for curing, 2~6 times a day. 2. The curing temperature shall be above 15 ℃ and the curing period shall be 7 days. If the site temperature is low, the curing period can be appropriately extended. 3. Thermal insulation measures shall be taken for winter construction. 4. The formwork removal shall be carried out 24 hours after the pouring is completed, and the curing shall continue after the formwork removal. Jincheng track cement * * * price 3、 Product function 1. Grouting of crane rail groove in port and wharf (rail pressing plate grouting, bottom plate, bolt fixing, etc.). 2. It is suitable for primary and secondary grouting of various mechanical and electrical equipment (heavy equipment, high-precision grinder). 3.
