Mortar bearing manufacturers - Holders mortar Rates - Early strength mortar bearing factory direct special dry mortar factory-built Industrial Supply:! Shilong Li Gong 13,331,056,879 18,311,209,002 welcome to inquire, factory direct, ex-factory price, low price QQ85574781 early strength support Block mortar is industry-leading products, it is reasonable fraction of high strength aggregate of aggregates, high strength cement as binding agents, polymers as toughening, combined with high flow, micro-expansion, anti-segregation, anti- cracking and other additives, admixtures and other precise ratio of professional production from the dry mixture. Its performance indicators in line with "the Beijing-Shanghai high-speed railway performance concrete Shi Rules" and "Railway Bridge rubber bearing basin Interim technical conditions" national standards and technical requirements of the railway industry. It has formed a prefabricated beams, cast beams, large bridges (type) and other types of products, and the formation of construction techniques and ancillary equipment in winter -10 ℃ ~ -20 ℃ conditions. For users to work in all weather conditions. Features ※ bearing mortar has excellent mobility, gravity leveling, no vibration, wiping pressure, the construction speed, convenience. ※ hour with a very high intensity, high late strength, not shrink. Depending on the application temperature, two hours to get 20-40Mpa compressive strength, flexural strength. ※ with micro-expansion properties and excellent resistance to cracking. ※ adapt to a wide temperature range, at -5 ℃ ~ -35 ℃ condition, without any auxiliary heat or cooling measures can be construction. At high or low temperatures, can simultaneously ensure the strength development and construction needs liquidity. ※ adapted to the repairs, the track is filled, bearing grout, especially for high-speed rail bridge bearing or track such as filling. It can also be used for leveling concrete beams or concrete piers partial repair. ※ accord "Passenger Dedicated precast concrete beams Interim technical conditions" and "Railway Bridge rubber bearing basin Interim technical conditions" requirements bearing mortar test data; No. Test Item Test Block 1 Test 2 Test Block 3 Block Test Block 41 Setting time / min initial setting and final setting ≥30 ≥30 ≥30 ≥30 ≤180 ≤180 ≤180 ≤180 2 Fluidity / mm initial ≥320 ≥320 / ≥320 30min ≥240 ≥240 / ≥240 3 bleeding rate / % 00/04 compressive strength / MPa 2h ≥20 / / / 3h / / / ≥25 8h / ≥25 ≥25 / 24h / ≥40 / ≥40 28d ≥50 ≥50 ≥50 ≥50 56d ≥28d strength ≥28d strength ≥28d strength ≥28d strength 90d ≥56d strength ≥56d strength ≥56d strength ≥56d strength 5 flexural strength / MPa 24h ≥10 ≥6 ≥10 ≥6 28d ≥10 / ≥10 6 elastic modulus / GPa 28d ≥30 ≥30 ≥30 ≥30 7 expansion (standard curing) /% 28d 0.02-0.1 / 0.02-0.1 / 8 expansion (water dependent) /% / ≥0.1 / ≥0.1 9 shrinkage /% / <2.0 / <2.0 Scope seat holder mortar mortar for road, railway bridge bearing installation of high-quality cement-based composite materials. Because it uses a variety of high-performance additives, especially after the completion of the surface smooth. To overcome the traditional mortar uneven, cracking, spalling and other shortcomings, with self-leveling, high early strength, high strength, non-shrink, high wear resistance and construction and other convenient features. Supports mortar construction methods: 1, bearing pad stone surface mount installation site cutting hair, remove debris left in the bolt holes, and then with water saturated bearing pad stone surface wet, but not out of water during construction. 2, the mounting bracket in place, with a small steel wedge wedging seat around, adjust the seat to the design elevation, between the bottom surface of the support bearing pad stone should be left 20-30mm gaps. 3, carefully check the bearing central location and elevation, install grout template, and the top surface of the pad stone should take credible measures to prevent leakage of slurry in gravity filling. Gravity perfusion bearing grouting material grouting methods. Filling should be required before a preliminary measure paste volume, the number of actual perfusion should not calculate the value of the slurry produced a large error, preventing intermediate lack pulp. 4, the ratio of water = 0.135-0.15 (weight ratio) preparation. Water was added to the mixing bucket should be first, and then gradually added weighed grout, side by side feeding electric mixer gun stirred until the powder all finished, then continue stirring for 2-3 minutes, the slurry evenly. The mixed slurry should be completed within 10 minutes infusion. After 5 to be filling material reaches a predetermined intensity, removal of the template and steel wedges, check whether tainted plasma, plasma leakage of clearance at the rear and steel wedges were drawn up pulp, tighten the bolt, then install the beam holder floor and seat sealing panels.
