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的強度不僅取決于水泥基材，還取決于玻纖的含量、長度以及玻纖的分布和方向。在通常情況下，纖維呈二維亂向分布，且分布方向與板平面平行。因此其強度沿板的不同方向而異。GRC綜合物理力學(xué)版性能中重要的試驗是彎曲性能試驗，以確定GRC的比例極限(LoP)和斷裂模數(shù)(MOR)，因為這是構(gòu)件設(shè)計中使用的主要數(shù)據(jù)。

　　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不能直接用標(biāo)準強度進行設(shè)計。GRC的設(shè)計強度遠遠低于標(biāo)準強度。

　　GRC cannot be designed directly with standard strength. The design strength of GRC is much lower than the standard strength.
             

　　1、玻璃纖維的增強作用隨時間衰減

　　1. The strengthening effect of glass fiber decreases with time

　　GRC中起增強作用的玻璃纖維受水泥石中堿的侵蝕，隨時間其增強作用會降低，GRC抗彎極限強度隨之大幅度降低。以早期抗彎強度標(biāo)準值作為設(shè)計強度，無法保證GRC整個壽命期的使用。所以GRC設(shè)計時采用的強度一定要將衰減因素考慮進去，不能直接采用標(biāo)準強度。

　　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、實際構(gòu)件強度與標(biāo)準試塊強度存在差異

　　2. There are differences between the actual component strength and the standard block strength

　　GRC標(biāo)準強度是從標(biāo)準試塊的實驗中得到的，而實際GRC構(gòu)件的厚度、造型和產(chǎn)品質(zhì)量與標(biāo)準試塊可能存在差異，設(shè)計強度要考慮這些差異。

　　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.
