Product Description seal anchor mortar, is a new product of our company for high-speed railway passenger dedicated line plate seal anchor development. The product has good mechanical properties, low content of harmful ions and contraction properties, high impermeability and crack resistance, the product is easy on-site construction, able to track slab tendons effectively protected. The product can bind strongly with the surrounding concrete, cracking, corrosion of prestressing steel plate to prevent the track, can significantly improve the durability of concrete track slab.
