Increasing Load-bearing Capacity of Bridge Structures by Reducing Cover Thickness as a Result of Changing Cement Type

This paper discusses how cover thickness is selected based on values of diffusion coefficients regarding its durability by obtaining the limit concentration of chlorides at its surface, typical for Portland cement CEM I 42.5R and Portland cement with low alkali content CEM I 42.5N/SR3/NA, and considering the example of a beam bridge structure - the impact of cover on load- bearing capacity as a function of span.
