对于GRC构件相信大家都会比较熟悉，grc构件是一种装饰材料，凭借具有的优势而深受人们的喜爱，在生活中也是非常常见的。接下来为大家详细介绍一下GRC设计强度与标准强度的区别，希望对大家能有所帮助。
For GRC components, I believe that we will be more familiar with, GRC components is a kind of decorative materials, with its advantages and deeply loved by people, in life is also very common. Next, we will introduce the difference between GRC design strength and standard strength in detail, hoping to help you.
GRC的强度不仅取决于水泥基材，还取决于玻纤的含量、长度以及玻纤的分布和方向。在通常情况下，纤维呈二维乱向分布，且分布方向与板平面平行。因此其强度沿板的不同方向而异。GRC综合物理力学版性能中重要的试验是弯曲性能试验，以确定GRC的比例极限(LoP)和断裂模数(MOR)，因为这是构件设计中使用的主要数据。
The strength of GRC depends not only on the cement base material, but also on the content, length and distribution and direction of glass fiber. In general, the fibers are randomly distributed in two dimensions, and the distribution direction is parallel to the plate plane. Therefore, the strength varies with the direction of the plate. An important test in the comprehensive physical and mechanical properties of GRC is the bending performance test to determine the proportional limit (LOP) and modulus of rupture (MOR) of GRC, which are the main data used in the design of members.
GRC不能直接用标准强度进行设计。GRC的设计强度远远低于标准强度。
GRC cannot be designed directly with standard strength. The design strength of GRC is much lower than the standard strength.
1、玻璃纤维的增强作用随时间衰减
1. The strengthening effect of glass fiber decreases with time
GRC中起增强作用的玻璃纤维受水泥石中碱的侵蚀，随时间其增强作用会降低，GRC抗弯极限强度随之大幅度降低。以早期抗弯强度标准值作为设计强度，无法保证GRC整个寿命期的使用。所以GRC设计时采用的强度一定要将衰减因素考虑进去，不能直接采用标准强度。
The glass fiber reinforced by GrC is eroded by alkali in cement paste, and its strengthening effect will decrease with time, and the ultimate bending strength of GRC will decrease greatly. Taking the standard value of early flexural strength as the design strength can not guarantee the safe use of GRC in the whole life cycle. Therefore, the strength used in GRC design must take into account the attenuation factor, and the standard strength cannot be directly used.
2、实际构件强度与标准试块强度存在差异
2. There are differences between the actual component strength and the standard block strength
GRC标准强度是从标准试块的实验中得到的，而实际GRC构件的厚度、造型和产品质量与标准试块可能存在差异，设计强度要考虑这些差异。
The standard strength of GRC is obtained from the experiment of standard test block, but the thickness, shape and product quality of actual GRC component may be different from that of standard test block, and these differences should be considered in design strength.
