GRC構件的質量既受到時間的考驗，又受到使用環境的侵蝕，因此構件重要的一點就是要耐用。那么主要體現在哪些方面呢?下面跟著
山東GRC構件廠家一起來看看吧。
The quality of GRC components is not only tested by time, but also eroded by the service environment. Therefore, it is important for components to be durable. What are the main aspects? Now let's follow Shandong GRC component manufacturers to have a look.
1、抗滲性
1. Impermeability
壓力水通過其內部的能力。如果抗滲性差，GRC構件中的鋼筋容易生銹，影響構件的壽命，影響抗滲性的因素主要有水泥品種、用量、砂礫粒徑大小和級配,水灰比的大小和構件的密度。
The ability of pressurized water to pass through its interior. If the impermeability is poor, the reinforcement in the GRC component is easy to rust, which affects the service life of the component. The factors affecting the impermeability mainly include the type and amount of cement, the size and grading of sand gravel, the size of water cement ratio and the density of the component.
2、抗凍性
2. Frost resistance
在飽和水狀態下受凍時，抵抗凍結破壞的能力。 這是因為，其內部存在很多連通或非連通的空隙，這些空隙成為水分的通道和蓄水池，GRC構件在飽和水的狀態下被凍結，內部水分凍結，體積膨脹8%，孔隙膨脹，產生拉伸應力。因此，通過反復融化凍結的循環，當拉伸應力超過拉伸強度時，徽章開始產生龜裂，有可能逐漸擴大并與龜裂結合，然后使其開裂并破壞。
The ability to resist freezing damage when frozen in saturated water. This is because there are many connected or disconnected voids in the GRC. These voids become the channels and reservoirs of water. GRC components are frozen in the state of saturated water. The internal moisture is frozen, and the volume expands by 8%. The pores expand, producing tensile stress. Therefore, through the cycle of repeated melting and freezing, when the tensile stress exceeds the tensile strength, the badge begins to crack, which may gradually expand and combine with the crack, and then crack and destroy it.
3、耐蝕性
3. Corrosion resistance
GRC構件在使用環境中抵抗外界侵蝕介質腐蝕的能力。 例如抵抗酸、鹽類化學介質的侵蝕、堿骨料的反應、碳化等。這些介質的侵蝕都會降低強度，破壞結構體積，影響壽命。
The ability of GRC components to resist the corrosion of external corrosive media in the service environment. For example, it can resist the corrosion of acid and salt chemical media, the reaction of alkali aggregate, carbonization, etc. The erosion of these media will reduce the strength, destroy the structure volume and affect the service life.
The above are the three performances of grc components, mainly including impermeability, frost resistance and corrosion resistance, which are more important. It depends on the quality of components. I hope that the content shared can help you. Follow us http://m.libpo.com.cn Learn more!
