Research and Prediction on Carbonation of Aeolian Sand Concrete
摘要
Abstract
It has great social and economic benefits by replacing the ordinary river sand with aeolian sand(known as desert sand)partially or totally to mix concrete.Consequently,reach on the durability of aeolian sand concrete under complex environment has great significance because of the nasty weather of desert.The concrete block was designed with different contents of aeolian sand(0,20％,40％,60％,80％,100％)and standard cured for 28 d in order to study on the regularity of carbonation in the laboratory after 3 d,7 d,14 d,21 d and 28 d.In addition,the mathematical expression was obtained by MATLAB matching,in which the CO2 diffusion coefficient of aeolian sand had been proved to be changed by different contents of aeolian sand.And the prediction model of carbonation depth with aeolian sand contents as the main parameter was established.The establishment of the model provides an important reference for the application of aeolian sand concrete in the desert and its surrounding areas.关键词
