What elements should be considered for the general requirements of GRC components?
構件在我們現在的生活中非常重要。GRC構件一般安裝在室外，經常暴露在風雨中，導致各種情況。原因是GRC組分中的水分蒸發，影響GRC組分的強度。GRC構件的一般要求應考慮哪些要素？
山東GRC構件的制造商將通知您。
Component is very important in our present life. GRC components are generally installed outdoors and often exposed to wind and rain, resulting in various conditions. The reason is that the evaporation of water in GRC components affects the strength of GRC components. What elements should be considered for the general requirements of GRC components? The manufacturer of Shandong GRC components will inform you.
一個GRC構件安裝完畢后，用防水涂料或油漆停止GRC構件的維修。這主要是為了避免水分蒸發。另一方面，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，所以有必要再次停止使用；
After the installation of one GRC component, the maintenance of GRC component shall be stopped with waterproof coating or paint. This is mainly to avoid water evaporation. On the other hand, it is to prevent it from contacting with air and thus forming rust on the internal reinforcement and losing its use. Of course, the coating will be weathered after a period of time, so it is necessary to stop using again;
停止定期清潔。使用一段時間后，GRC表面會有很多污漬。我們可以用不到80的高壓水槍停止清洗，但強度不宜過大，否則會損壞部件。應特別注意定期停止這一清潔要求；
Stop regular cleaning. After a period of use, there will be many stains on the surface of GRC. We can stop cleaning with a high-pressure water gun less than 80, but the strength should not be too high, otherwise the parts will be damaged. Special attention should be paid to stopping this cleaning requirement regularly;
防止陽光直射。如果是室外構件，本聲明可能不完整，但如果是室內GRC構件，防止陽光直射可以很好地延長其使用壽命。當然，也需要防水涂料。
Prevent direct sunlight. If it is an outdoor component, this statement may not be complete, but if it is an indoor GRC component, its service life can be well extended by preventing direct sunlight. Of course, waterproof coating is also required.
因此，我們需要采取有效的維修方法，并適當的早期強度，以便于脫模和搬運，從而保證設計強度，并限制收縮，避免開裂。養護可使水泥水化正常停止，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，加上溫度控制。
Therefore, we need to take effective maintenance methods and appropriate early strength to facilitate demoulding and handling, so as to ensure design strength, limit shrinkage and avoid cracking. Curing can stop cement hydration normally 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 put, water replenishment is the basis of solidification, plus temperature control.
脫模前后，模具通常用干凈的聚乙烯薄膜包裹，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傳熱。
Before and after demoulding, the mold is usually wrapped with clean and high-quality polyethylene film, which is also to avoid the influence of moisture evaporation and wind in GRC, and also to adhere moisture for heat transfer.
In addition, at the early stage of maintenance, GRC members shall have sufficient strength to prevent damage during demoulding and handling. Especially in some areas, it is required to stop heating GRC components and keep the temperature above 15 ℃. Follow us http://www.libpo.com.cn , learn more!
