本文根据大量工程调查结果,将一般大气环境分为一般室内环境和室外或室内潮湿环境两大类,基于腐蚀电化学原理,提出了预测钢筋锈蚀量的数学模型。文中具体建立了两类环境钢筋锈蚀开裂前和锈蚀开裂后的锈蚀量计算公式,考虑环境相对湿度和水膜对氧气的吸收能力对公式进行了修正.最后分析了钢筋锈蚀量与各影响因素之间的关系.
According to the results of a large number of engineering surveys, this paper divides the general atmospheric environment into general indoor environments and outdoor or indoor wet environments. Based on the electrochemical principle of corrosion, a mathematical model for predicting the amount of corrosion of reinforcing bars is proposed. In this paper, formulas for calculating the amount of rust before and after corrosion corrosion cracking of two types of environmental steel reinforcement were established. The formula was revised by taking into account the relative humidity of the environment and the ability of the water film to absorb oxygen. Finally, the amount of corrosion of steel bars and the influence factors were analyzed. The relationship between.
