Corrosion Behavior of Fiber-Reinforced Concrete—A Review Ganesh Naidu Gopu, Sofi Androse Joseph Fibers, 2022 Corrosion study of conventional reinforcement in concrete has been accorded wider importance in the last few decades based on the losses occurring in monitoring concrete structures. It is well known that the presence of chloride ions is one of the most significant factors contributing to the corrosion of reinforcing steel. Practically, it is observed that in the marine environment, the activating substances such as chlorides that penetrate the steel can counteract the passivity locally when the electrolyte is highly alkaline. The concrete cover is changed chemically when chloride ionspenetrate into the material, whereupon the pore solution is neutralized. Based on numerous studies, it is evident that steel fibers and glass fibers have less impact on cracked sections in a chloride environment and can oppose chloride infiltration. Glass fibers, when exposed to repeated freeze and thaw conditions, protect the passive layer. This review article highlights the corrosion behavior of reinforced concrete involving various factors such as cracking behavior, transportation, electric conductivity, resistivity, and diffusion of chloride ions in the presence of steel and glass fibers.

A review on mechanical properties of self compacting concrete incorporated with various types of plastic waste aggregates Ganesh Naidu Gopu, Rakesh Reddy Thummala, M. Sri Durga Vara Prasad, Siva Koti Thottempudi Materials Today Proceedings, 2022 Plastic Waste has a need of recycling from its non degradable behaviour and over disposition, which can lead to the release of hazardous gases into the atmosphere. To improve the sustainability and to reduce depletion of natural resources, plastic waste is adopted in many fields like construction, infrastructure, architecture, tiles and coatings etc. A common building material is concrete, and as the world's population grows, so does the need for it. Stating the above scenario, natural resources like sand, gravel and other constituents of concrete are depleting gradually. To overcome the situation, constituents are usually replaced by solid waste available in the nature. Self compacting concrete (SCC) is used in structures that has closely packed reinforcement, where any mechanical means of vibration for compaction cannot be adopted and in improving the strength of the structure. In this paper, most recent literature on various types of recycled plastic replaced waste and its influence on the mechanical behaviour of self compacting concrete were reviewed. The purpose of this review was to examine the academic and practical relationships between several mechanical parameters. This concrete with plastic aggregate can give a sustainable concrete to reduce the adverse effects of plastic waste on environment.
Development of ultra strength concrete Ganesh Naidu Gopu, Sri Durga Vara Prasad M, Swaroop Babu Mylavarpu, S Ankarao Journal of Physics Conference Series, 2021 Most superior cements delivered today contain materials notwithstanding Portland cement to help accomplish the compressive strength or solidness execution. These materials include fly ash, silica fume and ground-granulated blast furnace slag used discretely or in coalescence. Concurrently, chemical admixtures such as high-range di-hydrogen monoxide-reducers are needed to ascertain that the concrete is facile to convey, place and culminate. For high-strength cements, a blend of mineral and compound admixtures is almost consistently fundamental to guarantee accomplishment of the necessary strength. The Primer investigations have been done on concrete, Fine aggregate and coarse aggregate. The Blend Extent for M200 grade concrete is determined 1: 0.313: 1.463 by following the plan methodology given by ACI Strategy. By keeping up the w/c proportion as 0.25, the multi day Compressive strength, Flexural strength and Split elasticity of cement at 3% of silica fume and 1.5% of conplast have been accomplished as 163.33 N/mm2, 8.4 N/mm2& 9.5 N/mm2 separately. The variety of solidarity of cement with the variety of silica fume is appeared in bar outline. The strength of the concrete might be as yet expanded by decreasing the w/c proportion and expanding the level of silica fume
Influence of granite cutting waste on mechanical properties of recycled aggregate concrete Ganesh Naidu Gopu, M Sri Durga Vara Prasad, Sugandham Kaumanu, P Ravi Kumar Journal of Physics Conference Series, 2021 Solid waste disposition has been a growing problem in many developed and under-developing nations. Major part of development was constituted by construction and infrastructure; on the contrary these industries also lead to release of carbon dioxide into the atmosphere. To overcome these disadvantages; in this research, recycled aggregates from construction waste and granite cutting waste were adopted as a replacement of coarse aggregate and cement respectively. Mechanical properties of recycled aggregate (RA) concrete are tested by replacing coarse aggregate varying from 0% to 100% with a difference of 25% and cement is replaced with Granite cutting waste (GCW) varying from 0% to 20% with a difference of 5%. Mix designation and fresh properties were also presented. Results were plotted and compared with the normal concrete to predict the most optimal values of the replacement. Mix containing 25% of RA and 15% of GCW replaced has shown a notable difference in strength comparing with the normal aggregate concrete.
Electrical waste fibers impact on mechanical and durability properties of concrete Ganesh Naidu Gopu, A. Sofi Civil Engineering and Architecture, 2021 Major aspects that were considered while designing a structure are safety and serviceability. Serviceability is also called as life span of structure reduces, when exposed to severe environments. Solid waste management in developing nations has been growing everyday, which influenced the scientists and researchers around the world in recycling and application of solid waste in various fields. Introduction of waste and recycled fibers in concrete is quite prominent from last few decades. In this research, electric waster copper fibers (EWCF) are added to concrete to test mechanical properties and chloride ion penetration that could reduce the durability of concrete. Adopted percentages of copper fibers added to the concrete are 0, 0.25, 0.5, 0.75, 1.00, 1.25, 1.50, 1.75 and 2.00 for volume of concrete. Concrete introduced with EWCF was tested for compression, tensile, flexural and elastic modulus to determine mechanical behavior. Most optimal EWCF percentage of replacement that increased the strength of concrete is 1.0% in volume of concrete. Water absorption, sorptivity, acid attack, bulk diffusion and rapid chloride penetration test (RCPT) were performed on concrete with EWCF to evaluate the durability and microstructure performance. E-Glass and Steel fibers were also adopted in the study to compare the mechanical properties and durability. Optimum values for both strength and durability were determined from the experimental test results.
