GRC構(gòu)件的質(zhì)量既受到時(shí)間的考驗(yàn)，又受到使用環(huán)境的侵蝕，因此構(gòu)件重要的一點(diǎn)就是要耐用。那么主要體現(xiàn)在哪些方面呢?下面跟著山東GRC構(gòu)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?jié)B性

1. Impermeability

壓力水通過其內(nèi)部的能力。如果抗?jié)B性差，GRC構(gòu)件中的鋼筋容易生銹，影響構(gòu)件的壽命，影響抗?jié)B性的因素主要有水泥品種、用量、砂礫粒徑大小和級(jí)配,水灰比的大小和構(gòu)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(tài)下受凍時(shí)，抵抗凍結(jié)破壞的能力。 這是因?yàn)?，其?nèi)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(gòu)件在飽和水的狀態(tài)下被凍結(jié)，內(nèi)部水分凍結(jié)，體積膨脹8%，孔隙膨脹，產(chǎn)生拉伸應(yīng)力。因此，通過反復(fù)融化凍結(jié)的循環(huán)，當(dāng)拉伸應(yīng)力超過拉伸強(qiáng)度時(shí)，徽章開始產(chǎn)生龜裂，有可能逐漸擴(kuò)大并與龜裂結(jié)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(gòu)件在使用環(huán)境中抵抗外界侵蝕介質(zhì)腐蝕的能力。 例如抵抗酸、鹽類化學(xué)介質(zhì)的侵蝕、堿骨料的反應(yīng)、碳化等。這些介質(zhì)的侵蝕都會(huì)降低強(qiáng)度，破壞結(jié)構(gòu)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.

以上就是grc構(gòu)件的三點(diǎn)性能，主要是抗?jié)B性、抗凍性和耐蝕性，這是比較重要的，看構(gòu)件質(zhì)量如何看這三點(diǎn)就可以了，希望分享的內(nèi)容能對(duì)大家有所幫助。關(guān)注我們http://1111tk.cn帶您了解更多！
