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.

一個GRC構件安裝完畢后，用防水涂料或油漆用于構件的保養。這主要是為了避免水分蒸發。另一方面，也是為了防止與空氣接觸，從而在內部鋼筋上形成鐵銹而失去使用。當然，涂層在一段時間后會被風化，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.

要定期清潔。使用一段時間后，這種構件的表面會有很多污漬。我們可以用不到80壓力的高壓水槍來清洗，但強度不宜過大，否則會損壞部件。應特別注意定期清潔這一要求;

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;
                 

防止陽光直接照射。如果是室外GRC組件，一定要做好相應的防曬措施，比如實施遮蓋或者涂刷相應的防曬物質，防止陽光直射可以很好地延長其使用壽命。當然，但如果是室內GRC組件，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，我們需要采取有效的維修方法，并適當的加大強度，以便于脫模和搬運，從而設計強度，并限制收縮，避免開裂。養護可使水泥化停止，增強強度和粘結性。它需要在很大程度上減少體積損失、收縮和可能出現的開裂。為了控制水的流失，簡單地說，補水是固化的基礎，同時加上溫度的控制。脫模前后，模具通常用干凈質量好的聚乙烯薄膜包裹，這也是為了避免GRC中水分蒸發和風的影響，同時也為了粘附水分與傳熱。此外，在維護的早期階段，GRC構件應具有足夠的強度，以防止在脫模和搬運過程中損壞。特別是在一些地區，要求停止對GRC組件的加熱，使溫度保持在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構件具有強度高、韌性大、吸收率低、綠色、不易褪色、成本低、重量輕等特點。與主體建筑具有同等的服務壽命。對美化建筑環境做出了巨大貢獻，成為建筑企業界非常流行的裝飾材料。

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.
