Assessment of Chloride Migration Coefficient, Internal Frost Resistance, Salt Frost Scaling and Sulphate Resistance of Self-Compacting Concrete

Authors: Bertil Persson, Lund University.

Abstract

In this project the objectives were to investigate the chloride migration coefficient, D, defined by Tang, to determine the salt frost scaling, the internal frost resistance and the sulphate resistance of SCC that contains increased amount of filler, different types of casting and air content. The objective was also to compare the result of salt frost scaling, internal frost resistance, sulphate resistance and chloride ingress of SCC with the corresponding properties of normal concrete, NC, with the same water-cement ratio, w/c = 0.39. Finally the objective was to give recommendations how to produce a SCC durable to frost and chlorides.
