Deduction of A Discriminant of Groundwaters Carbonic Acid Erosion to the Concrete
Based on analysis of the two main deficiencies of the current evaluation methods of carbonic acid erosion of groundwater to the concrete in China: a). the carbonic acid erosion indexes CO2s of different water samples have no comparability with each other; b). It is difficult to draw carbonic acid erosion partitioning map, a universal discriminant of groundwater was deduced in this article. By employing special compiled calculation procedure of discriminant of carbonic acid erosion, not only calculation of the newly defined discriminant of carbonic acid erosion has been completed, but also the calculation of carbonic acid erosion indexes CO2s by artificial table checking and interpolation in the past has been realized in computer. With the help of the discriminant and the calculation procedure proposed in this paper, not only horizontal comparison of the carbonic acid erosion between water samples is feasible, but also the partitioning map of the carbonic acid erosion can be compiled quantitatively. Furthermore, the two main deficiencies of the current evaluation method and the feasibility of drawing carbonic acid erosion partitioning map quantitatively by the discriminant in this paper the are shown in cases.
