摘要
钢筋混凝土具有较高的承载力和较好的受力性能,而且钢筋与混凝土具有近似相同的膨胀系数,不会因为环境不同而产生过大的应力,而混凝土与钢筋能够共同工作主要是依靠混凝土与钢筋之间有足够的粘结力。为了使钢筋更好更持久使用性能,则需要钢筋保护层,试验表明,钢筋的保护层厚度是影响钢筋与混凝土之间粘结力大小的主要因素。因此对于钢筋混凝土来说,钢筋保护层显得格外重要。
Reinforced concrete has high bearing capacity and good mechanical properties,and steel and concrete have approximately the same expansion coefficient.It does not cause excessive stress due to different environments.The concrete and steel bars can work together mainly rely on sufficient adhesion between concrete and steel.In order to make the steel have better and lasting performance,a protective layer of steel is needed.The test shows that the thickness of the protective layer of the steel is the main factor affecting the bond strength between the steel and the concrete.Therefore,for reinforced concrete,the protective layer of steel is particularly important.
