GRC构件的质量既受到时间的考验,又受到使用环境的侵蚀,因此构件重要的一点就是要耐用。那么主要体现在哪些方面呢?下面跟着
山东GRC构件厂家一起来看看吧。
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、抗渗性
1. Impermeability
压力水通过其内部的能力。如果抗渗性差,GRC构件中的钢筋容易生锈,影响构件的寿命,影响抗渗性的因素主要有水泥品种、用量、砂砾粒径大小和级配,水灰比的大小和构件的密度。
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、抗冻性
2. Frost resistance
在饱和水状态下受冻时,抵抗冻结破坏的能力。 这是因为,其内部存在很多连通或非连通的空隙,这些空隙成为水分的通道和蓄水池,GRC构件在饱和水的状态下被冻结,内部水分冻结,体积膨胀8%,孔隙膨胀,产生拉伸应力。因此,通过反复融化冻结的循环,当拉伸应力超过拉伸强度时,徽章开始产生龟裂,有可能逐渐扩大并与龟裂结合,然后使其开裂并破坏。
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、耐蚀性
3. Corrosion resistance
GRC构件在使用环境中抵抗外界侵蚀介质腐蚀的能力。 例如抵抗酸、盐类化学介质的侵蚀、碱骨料的反应、碳化等。这些介质的侵蚀都会降低强度,破坏结构体积,影响寿命。
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构件的三点性能,主要是抗渗性、抗冻性和耐蚀性,这是比较重要的,看构件质量如何看这三点就可以了,希望分享的内容能对大家有所帮助。关注我们
