GRC component is very important in our life. GRC components are usually installed outdoors and exposed to wind and rain, which leads to a variety of bad situations. The reason is that the evaporation of water in GRC affects the strength of GRC components. What factors should be considered for the general requirements of GRC components? The GRC component manufacturer will tell you.

一个GRC构件安装完毕后，用防水涂料或油漆用于构件的保养。这主要是为了避免水分蒸发。另一方面，也是为了防止与空气接触，从而在内部钢筋上形成铁锈而失去使用。当然，涂层在一段时间后会被风化，所以有必要再次涂刷。

After a GRC component is installed, waterproof coating or paint is used for component maintenance. This is mainly to avoid water evaporation. On the other hand, it is also to prevent contact with the air, so as to form rust on the internal reinforcement and lose use. Of course, the coating will be weathered after a period of time, so it is necessary to brush again.

要定期清洁。使用一段时间后，这种构件的表面会有很多污渍。我们可以用不到80压力的高压水枪来清洗，但强度不宜过大，否则会损坏部件。应特别注意定期清洁这一要求;

Clean regularly. After a period of use, there will be a lot of stains on the surface of this component. We can use the high pressure water gun with less than 80 pressure to clean, but the strength should not be too high, otherwise the parts will be damaged. Special attention should be paid to the requirement of regular cleaning;
                 

防止阳光直接照射。如果是室外GRC组件，一定要做好相应的防晒措施，比如实施遮盖或者涂刷相应的防晒物质，防止阳光直射可以很好地延长其使用寿命。当然，但如果是室内GRC组件，也需要防水涂料。

Prevent direct sunlight. If it is outdoor GRC components, it is necessary to take corresponding sunscreen measures, such as covering or brushing the corresponding sunscreen material, to prevent direct sunlight, which can well extend its service life. Of course, but if it is indoor GRC components, also need waterproof coating.

因此，我们需要采取有效的维修方法，并适当的加大强度，以便于脱模和搬运，从而设计强度，并限制收缩，避免开裂。养护可使水泥化停止，增强强度和粘结性。它需要在很大程度上减少体积损失、收缩和可能出现的开裂。为了控制水的流失，简单地说，补水是固化的基础，同时加上温度的控制。脱模前后，模具通常用干净质量好的聚乙烯薄膜包裹，这也是为了避免GRC中水分蒸发和风的影响，同时也为了粘附水分与传热。此外，在维护的早期阶段，GRC构件应具有足够的强度，以防止在脱模和搬运过程中损坏。特别是在一些地区，要求停止对GRC组件的加热，使温度保持在15℃以上。

Therefore, we need to take effective maintenance methods and increase the strength appropriately to facilitate demoulding and handling, so as to design the strength, limit the shrinkage and avoid cracking. Curing can stop cementation and enhance strength and cohesiveness. It needs to greatly reduce volume loss, shrinkage and possible cracking. In order to control the loss of water, simply speaking, make-up water is the basis of solidification, and temperature control is also added. Before and after demoulding, the mold is usually wrapped with clean and good quality polyethylene film, which is also to avoid the influence of moisture evaporation and wind in GRC, and also to adhere moisture and heat transfer. In addition, at the early stage of maintenance, GRC members should have sufficient strength to prevent damage during demoulding and handling. Especially in some areas, it is required to stop heating GRC components to keep the temperature above 15 ℃.

GRC构件具有强度高、韧性大、吸收率低、绿色、不易褪色、成本低、重量轻等特点。与主体建筑具有同等的服务寿命。对美化建筑环境做出了巨大贡献，成为建筑企业界非常流行的装饰材料。

GRC components have the characteristics of high strength, high toughness, low absorption rate, green environmental protection, not easy to fade, low cost, light weight and so on. It has the same service life as the main building. It has made a great contribution to beautify the building environment and has become a very popular decoration material in the construction industry.
