M50 harsh non-shrinkage mortar bearing special performance

M50 harsh non-shrinkage mortar M50 harsh non-shrinkage mortar price M50 harsh non-shrinkage mortar bearing manufacturer M50 harsh non-shrinkage mortar mortar is a leading professional products, it at a reasonable level points of high strength aggregate as aggregate, high strength cement as in combination with the seam an agent, polymer toughening the seam an agent, complementary with high flow, micro swell, segregation, cracking resistance and beautiful seam an agent, such as admixture accurate. Professional production of dry mixing proportion. M50 harsh non-shrinkage mortar support mortar used in railway bridge bearing installation of high quality cement base composite materials. Because of its USES a variety of high performance to add the seam an agent, special lubrication flat finished appearance. Overcomes the shortcomings, such as traditional mortar uneven, craze, fall off a self-leveling, high early strength, high strength, no shorter, high wear resistance and the construction convenience features. Its performance goals fit the beijing-shanghai high speed railway implementing rules for the high performance concrete applied to the interim skills on passenger dedicated line bridge pot rubber bearing conditions, such as national professional standards with the railway skill requirements.
