TLDR
In this article, the authors evaluated the practical corrosion resistance of rebar induced various forms of concrete reinforced with fiber and found that E-glass fiber reinforced concrete induced rebar is high corrosion resistivity compared to control concrete, steel fibre reinforced concrete and E-waste copper wire fibre reinforcedcrete specimens.Abstract:
Based on the early studies it is evident that fibre reinforced concrete exhibits good results in strength and workability compared to conventional concrete. This research work evaluates the practical corrosion resistance of rebar induced various forms of concrete reinforced with fibre. In this study, three multiple types of concrete reinforced with E-waste copper wire, steel fibre and E-Glass fibre at a constant percentage of 1% were used. To evaluate corrosion characteristics of rebar introduced in fibre reinforced concrete accelerated corrosion test and standard test method as per ASTM G109 were conducted. Test results were compared for all three types of fibre reinforced concrete. Results showed that E-Glass fibre reinforced concrete induced rebar is high corrosion resistivity compared to control concrete, steel fibre reinforced concrete and E-waste copper wire fibre reinforced concrete specimens.read more

Waste E-glass particles used in cementitious mixtures
TL;DR: In this article, the properties of concretes containing various waste E-glass particle contents were investigated in a study, where the size distribution of cylindrical glass particle was from 38 to 300 {mu}m and about 40% of Eglass particle was less than 150 µm, and the workability decreased as the glass content increased due to reduction of fineness modulus.

Corrosion behavior of steel reinforcement in concrete exposed to composite chloride–sulfate environment
TL;DR: In this article, a comprehensive experimental investigation is presented wherein corrosion performance of steel reinforcement in concrete exposed to composite solutions of chloride and sulfate ions has been evaluated, in which concrete specimens with a centrally embedded steel bar have been prepared from two types of cement namely ordinary Portland cement (OPC) and Portland pozzolana cement (PPC), four w/c ratios and one type of reinforced concrete.
