Effect of different alkali salt additions on concrete durability property

Effect of different alkali salt additions on concrete durability property AbstractFriedel’s salt (FS) is a versatile material and has several advantages in constructional and metallurgical sectors. In this paper, FS is formed in situ in concrete. The addition of Al2O3 (5% by weight of cement) was maintained constant and the formation of FS was proceed through the various ranges of NaCl, KCl and CaCl2.

Abstract

AbstractFriedel’s salt (FS) is a versatile material and has several advantages in constructional and metallurgical sectors. In this paper, FS is formed in situ in concrete. The addition of Al2O3 (5% by weight of cement) was maintained constant and the formation of FS was proceed through the various ranges of NaCl, KCl and CaCl2. Among them, CaCl2 addition was found effective in the large formation of FS in concrete. The influence of FS on the mechanical, permeability and corrosion resistance properties of concrete was studied by electrochemical techniques. X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron micrographs were used to characterize the formation of FS in concrete.
