Latest Patents

Yangdong Zhan holds a patent for a "Nano modified silicate capillary crystalline material and use method thereof." This invention provides a concrete durability protection method that involves several steps. The process begins with rinsing the concrete surface, followed by spraying agent A or a combination of agent A and agent B on the wet surface. This method effectively allows nanoscale active silicate to penetrate the concrete surface, reacting with free calcium ions to form C-S-H crystalline structures. The result is an improvement in the compactness of the concrete surface, repairing defects such as capillary interstices, pores, and microcracks. The unreacted nanoscale active silicate maintains permanent activity, allowing it to recover and continue reacting with moisture, thus ensuring ongoing durability protection for concrete.
