Experimental investigation of utilizing chemical additives and new generation corrosion inhibitors on reinforced concrete

Abstract

Corrosion is the most common structural defect in today's construction industry and therefore requires the most precautionary measures. As a result of corrosion, the repair of the structure causes high costs or is not possible at all. Corrosion inhibitors are the fastest and easiest method to take on corrosion, but many inhibitors used today contain components harmful to the environment and toxic. Today, there is hardly any concrete produced without using any chemical and mineral additives. Researchers are trying to produce less harmful concrete chemicals. In this study, calcium nitrite, which is the most widely used corrosion inhibitor in the market, and ecological boron inhibitor were compared with experimental methods. In addition, the interaction of chemical additives used most in concrete production with these inhibitors was investigated. As a result of experimental studies, it was concluded that the ecological boron inhibitor did not damage the structure of the reinforcement in the concrete and could be used instead of the calcium nitrite inhibitor produced in the market. The electrical resistance, rapid chloride permeability and half-cell potential experiments show that samples containing boron inhibitors gave the best results compared to other samples.

High Capacity and Rate Capability Binder‐less Ternary Transition Metal‐organic Framework as Anode Material for Lithium‐ion Battery

“…Narrow scan of Co 2p (Figure 3b) affirm the Co 2p 3/2 and Co 2p 1/2 peaks at 775.2 eV and 790.5 eV, respectively, with a spin‐orbital splitting (SOS) of Δ Co =15.3 eV. From the fitting of the two Co peaks and the SOS value, it was concluded that the hybrid MOF contains Co 2+ in the structure [63]. Similarly, the Cu 2p spectrum (Figure 3c) also shows two distinct peaks at binding energies of 929.1 eV and 946.2 eV, which corresponds to the Cu 2p 3/2 and Cu 2p 1/2 , respectively.…”

A Review on Adherence in Reinforced Concrete

“…As a variable parameter in these studies; type and cross-section of reinforced concrete element, concrete quality and composition (conventional concrete, high strength concrete), concrete additives, reinforcement type, diameter and hook/clamp length, etc. used [39][40][41][42][43][44][45][46][47][48][49][50][51]. In addition, the experimental methods used in most of the studies are pull-out [42,45,[51][52][53][54][55][56][57] and push-out.…”
