M50 harsh non-shrinkage mortar is specifically for passenger dedicated line prefabricated multi-plate bearing gravity grouting and developed, its performance fully meet the TB/T 2331 - Railway bridge pot bearing and TB/T 2013-3220 2013 ball bearing of railway Bridges. M50 harsh non-shrinkage mortar production base headquarters Yu Changping xing shou town, is currently the larger dry mortar production base in the province. M50 harsh non-shrinkage mortar multiple factories in zhengzhou, foshan, xian, chongqing, fuzhou, changchun, lanzhou, guilin, guiyang national shipping! Hotline 158 - manager li factory orders 3830 - 4411, the national customer service QQ447676452. A, M50 harsh non-shrinkage mortar properties: 1, the micro expansion function to ensure the slurry and the strong bond of grouting place, make the load function effectively passed to the base. 2, good workability, good dry mixing, as well as good cohesive force, not hierarchical segregation and no bleeding. 3, high early strength, compressive strength is greater than 8 hours 25 mpa. 4, high strength, 28 days compressive strength of 70 mpa, or high in the late strength and fail. 5, low construction: negative temperature under low temperature and negative temperature strength can still grow rapidly and effectively solved the problem of the winter construction. Fatigue test, durable performance is good: 2 million times, 50 times freeze-thaw cycling test, no obvious change in intensity; Impermeability, frost resistance, corrosion resistance are all in good performance. 7, do not contain chloride, effect on equipment, steel without any rust. Second, M50 harsh non-shrinkage mortar TB/T 2331 - performance test project 结核病/ T 3320 - 2013 20131 8 hours of 25 or higher compressive strength mpa28 acuity mpa56 50 days of no less than 28 days strength value not less than 56 days 90 days strength flexural strength 1 day or 2 10 mpa3 elastic modulus 28 days or 30 gpa4 vertical expansion rate 0 28 days. 02% ~ 0. Note: 1% above the M50 harsh non-shrinkage mortar technology indexes in the case of normal temperature and temperature measurement. Three, M50 harsh non-shrinkage mortar use method 1, prefabricated T beam stay before, first install the bearing at the bottom of the T beam, tighten the bearing plate on the bolt, the bearing plate and beam bottom shall not leave gaps between embedded steel plate, if there are any gaps, grouting methods should be taken to be populated, bearing assembly in the factory should be careful when leveling, on the upper and lower bearing plate, with a connecting plate bearing connected into a whole. 2, table surface treatment: to be grouted stone of bearing pad surface to remove dust, grease and other dirt is not conducive to bonding material, base application water wet to saturation, but construction, MingShui should not be maintained. Before 3, T beam beam at the top of the bearing pad stone spread a layer of 20 ~ 30 mm thick of M50 harsh non-shrinkage mortar, mortar top spread into the shape of a around slightly above middle, anchor bolt hole is also dao with corresponding M50 harsh non-shrinkage mortar. Sprinkler maintenance Gao Qianggan rigid non-shrinkage mortar in a timely manner. 4, harsh non-shrinkage mortar mixing water is 14 + / - 1% ( Weight ratio) Preparation. Should be first to add water to mixing barrel, then gradually add weighing good powder, while feeding, rob to stir with electric mixer, until the powder is added, and continue to stir 2 ~ 3 minutes, make the paste evenly. 5, multi-plate T beam, when installation should be lifting the middle two pieces T beam, and after the two pieces of T beam hoisting in place, timely welding two pieces of the T beam, the connection between the steel and symmetric lifting the rest of the T beam, after every piece of T beam in place, set up the temporary support, timely corresponding connection steel welding. Between June and T beam in laminated diaphragm plate after concrete pouring and achieve strength, dismantled pedestal connector plates and bolts, the installation pedestal coaming, test the bearing under normal working condition. Four, M50 harsh non-shrinkage mortar note 1, grouting material mixing at the scene, it is forbidden to add other material, so as not to affect the quality of the product. 2, use force mechanical stirring helps to play the best performance. If the artificial stirring, water consumption must be strictly controlled, and ensure the uniform mixing, in order to avoid adverse impact on the quality of product. 3, good mixing slurry should be finished within 30 minutes, the product may not continue to use after initial setting. Five, M50 harsh non-shrinkage mortar storage, shelf life M50 harsh slurry storage environment must be kept dry. M50 harsh non-shrinkage mortar shelf-life for six months, more than storage life of products subject to inspection qualified rear can use.
