Salt-Frost Scaling of Concrete with Slag and Fly Ash - Influence of Carbonation and Prolonged Conditioning on Test Results

Autor: Elisabeth Helsing, Peter Utgenannt

Publikováno v: Nordic Concrete Research. 63:89-108

According to Swedish experience the slab method in CEN/TS 12390-9 is successful in predicting the salt-frost resistance of Portland cement concrete. However, doubts have been raised whether the same can be said when used on concrete with supplementar

Redistribution of chlorides in concrete specimens occurring during storage

Autor: Elisabeth Helsing

Publikováno v: Materials and Structures. 54

It has been observed that storage of specimens with chloride gradients before determining the chloride profile can lead to changes in the shape of the chloride profile. An experimental study to quantify the influence of the duration of the storage pe
