The Chloride Penetration Depth of Self-Compacting Concrete Using Scanning Electron Microscopy

Abstract

Achieving a sustainable and durable concrete, with a minimum ecological impact is the current focus of the research in construction. Concrete durability design is based on the behavior of concrete in aggressive environments, one of which is the attack of chlorides. The main purpose of this paper is to test the resistance to chloride action of self-compacting concrete with fly ash addition, compared to self-compacting concrete with limestone addition. For this purpose, the colorimetric method and the scanning electron microscopy method are used, while evaluating the efficiency of the testing methods.
