There are different methods in these stages. After the modification of the grc before and during demoulding, we usually wrap the mold with clean and high-quality polyethylene film, which prevents the evaporation of the moisture contained in the grc and the impact of wind, and also helps to maintain the heat of hydration. During the period of maintenance, be careful not to damage them during handling. Hainan GRC component

Grc line

The main maintenance is to avoid the influence of sunlight, wind and low air humidity after the demoulding of grc components. During post curing, some simple methods should be taken to avoid direct sunlight during storage.

Grc members are generally thin-walled and low water cement ratio, but for grc clevis, they have a large surface area. Therefore, effective maintenance system should be adopted to achieve the most ideal maintenance. Hainan GRC component

GRC products are generally thin-walled and have low water cement ratio. For GRC clevis, it has a large surface area. Therefore, effective curing system should be adopted to achieve appropriate early strength to facilitate demoulding and handling; At the same time, it is necessary to ensure the design strength; Shrinkage should also be limited to prevent cracking;

During the actual implementation of GRC, we should wrap the mold with clean and high-quality polyethylene film before and after modification during demoulding. This method is mainly used to prevent the evaporation of water contained in GRC and the impact of wind, and it also helps to maintain the heat of hydration. Hainan GRC component

The GRC is mainly maintained after demoulding to avoid the influence of sunlight, wind and low air humidity. Generally, the GRC products are still wrapped with plastic film to avoid direct sunlight.
