混凝土碳化深度预测模型研究

Forecasting Model of Carbonization Depth of Concrete

对混凝土在酸性环境下腐蚀后的碳化深度进行研究,建立单变量的一阶灰色预测模型GM(1,1),对混凝土的碳化深度进行预测,并用加速腐蚀试验方法对混凝土碳化深度进行验证,研究结果表明,模型预测结果与试验结果能够较好地吻合,证明这种预测方法是简便易行的,可以作为研究受腐蚀混凝土的碳化深度的一种方法。

It studies the depth of carbonization of concrete eroded in acid environment,establishes a first-order grey forecasting model GM（1,1） with single variable to forecast the depth of carbonization of concrete,then validates it by accelerating erosion.The results show that the forecasting value is coincident with test value preferably,which proves that the prediction method is convenient and feasible and it can be an approach to study the depth of carbonization of concrete.
