Abstract
Temperature, relative humidity water-cement ratio, cement contents, strength of concrete etc. and many other parameters, conduct a carbonation model and it is really costly and time consuming to generate a model which is conducted by more parameters. But for maximum structural arrangements, it is not possible to allocate ample resources and time to continue this process. That is why, it is highly required to make sure a less parameter based model or to identify the best one for all performance. This paper work is based on that idea to identify the best model for concrete carbonation, which enables the solution makers to adopt the best situation easily. Two carbonation models were selected for determining the best model between the two models and also the accuracy of each model was checked. Error distribution method was implicated for checking the models. In the end, it was found that the less number of parameters concerned, the more ease and accuracy would be achieved in predicting carbonation depth.
