Item Environmental sustainability of waste glass as a valuable construction material - A critical review(EM International rktem@pn3.vsnl.net.in, 2018) Sudharsan, N.; Palanisamy, T.; Yaragal, S.C.The increased demand for concrete as a construction material leads to increase in cement production. The formulation of cement, emits a significant amount of CO2 to the atmosphere, which causes severe environmental pollution. Many efforts are being made to reduce the use of Portland cement in concrete to avoid environmental issues. These efforts mainly involve the utilization of value added materials in concrete. In this context, the waste glass powder has excellent pozzolanic properties, to use glass powder as a supplementary cementitious material in concrete. The use of waste glass powder in concrete has many economic and environmental benefits. This paper summarizes the literature regarding the utilization of waste glass powder as a supplementary cementitious material in mortar and concrete. © 2018 EM International.

Since Indian coal is of low grade with ash content of the order of 30–55% in comparison with imported coal which has low ash content of the order of 3–15%, huge piles of fly ash is left over which poses environmental degradation. In order to reduce its harmful effects on environment, we have to reuse/recycle this industrial by-product. As concrete contains 80% coarse aggregate, huge quantity of fly ash waste can be utilized if we reuse it as artificial coarse aggregate. This work compiles the results of a pilot scale study on durability properties of concrete made from fly ash-based artificial coarse aggregate (FACA). The molarity of NaOH, NaOH-to-Na2SiO3 ratio and alkaline-solution-to-fly-ash ratio used in this research are 8 M, 0.5 and 0.4 respectively. The coarse aggregate is produced by crushing the geopolymer mass in a crusher. The fundamental durability properties of the concrete (FACACRETE) prepared from FACA is compared with the conventional concrete (using crushed granite stone) at M20, M25 and M30 grades of concrete. It is observed that on increasing the grade of concrete, the ultrasonic pulse velocity test gives better result for both conventional concrete and FACACRETE. © 2022 Taylor & Francis Group, LLC.Item Study on performance of infilled wall in RC framed structure using basalt fibre in cement mortar(Structural Engineering Research Centre, 2019) Jagadeesan, P.; Palanisamy, T.Normally, Reinforced Concrete (RC) framed structure is built by combination of structural and non-structural elements that may satisfy the design and architectural purpose. When RC framed structures are subjected to the static lateral loading, infilled wall and RC frame elements does not react together. At this time, infilled wall is subjected only compressive forces and does not support the tensile force. So, failure is happened due to lacking of ductility and poor interaction between frame elements and infilled wall. Therefore, the objective of this study is to improve the ductility and interaction between RC frame elements and infilled wall through suitable method of strengthening of infilled wall. In this research work, the two types of specimens such as infilled RC framed structure and infilled RC framed structure strengthened by reinforced cement mortar using basalt fibre were cast and tested under experimental and analytical investigation. One-fifth scale model of single-bay, two-storey plane RC framed structure were prepared and tested under cyclic loading with the help of 1000 kN capacity loading frame and foundation block. This study focuses the significant parameters such as load-deflection curve, ductility, energy dissipation capacity, initial stiffness and failure mechanism of infilled RC frame and infilled RC frame with basalt fibre in cement mortar. The result proves that basalt fibre reinforced cement mortar improves the strength, stiffness and ductility of infilled RC framed structure and make infilled wall as integral unit in RC framed structure. © 2019 Structural Engineering Research Centre.

The use of mineral additives in light-weight concrete, to replace fine aggregate with fly ash and bagasse ash, helps to reduce the cement content. The present investigation aims to meet the performance of light weight concrete, by adding fly ash and bagasse ash, as fine aggregate replacement additives. The strength properties such as cube compressive strength, cylinder compressive strength and split tensile strength were investigated after different ages, to find the optimum addition of mineral additives such as fly ash and bagasse ash, in concrete. The strengths were compared and the optimal replacement level of cement with fly ash and bagasse ash was found. The cylinder compressive strength and split tensile strength of light weight concrete were measured, at the same replacement levels of mineral additives, at the age of 28 days curing. The mathematical equations were proposed to achieve cube compressive and tensile strengths, cylinder compressive and tensile strength and cube compressive and cylinder compressive strengths, concerning typical strength. © 2022, Foundation Cement, Lime, Concrete.

The investigation was carried out on the GPC using linear polarization resistance and Tafel plot techniques. All of the reinforced lollipop specimens were stored in a 3.5% NaCl solution with a steady anodic electrical potential of about 12 V applied to accelerate the corrosion process. Both the bond strength loss percentage and the mass loss percentage of the corroded steel rebar embedded in the concrete cylinder specimens were calculated. The test results showed that the OC condition demonstrated best corrosion resistance in the FA-GPC specimen compared to the FA-PSA GPC specimen. The test results for FA-PSA GPC specimens showed that their corrosion resistance performance was better under AC condition compared to the other two curing conditions. © 2022 The Authors.

It is tailor-made material for specific applications ha-ving beneficial properties. Therefore, the paper is devoted to the experimental analysis and study of fly ash and bagasse ash on the durability properties of lightweight concrete. Durability can be defined as the ability of the material to withstand the effects of its environment which are influencing the deterioration of concrete. The saturated water absorption and sorptivity was studied through experimental investigations, by varying the percentage of fly ash and bagasse ash content. Both fly ash and bagasse ash shows that the increase in the percentage of replacement leads to the more absorption of lightweight concrete. The results are investigated and presented on the studies conducted as follows, showing that the increases in the percentage of replacement, strength also increased. © 2022, Foundation Cement, Lime, Concrete.

The shear failure of the beam column joint should be avoided for the safety of the structure. In the present study, prediction of joint shear capacity of exterior Beam-column joint is proposed using artificial neural network (ANN). Experimental investigations performed by different authors have been examined and used to prepare the data sets for training, testing and validating the neural network. Parameters responsible for the shear strength of the exterior Beam-Column Joints are identified and the artificial neural network model is proposed to predict the joint shear strength. Input parameters for the ANN model are width and depth of the joint, concrete compressive strength, length of beam, top and bottom longitudinal reinforcement in the beam, yield strength of longitudinal reinforcement in beam, ratio of beam to column depth, joint Shear reinforcement index, beam bar index and column load index. The performance of the neural network model is evaluated by the statistical relations like Coefficient of correlation, Root mean square error and Scatter index. The proposed model is compared with an empirical formula and different equations suggested by the design codes. The results show that the proposed neural network model can effectively predict the joint shear strength of the Exterior Beam-Column joint. © 2022 Institution of Structural EngineersItem Influence of basalt fiber on the behavior of beam - column joint under cyclic loading(Elsevier Ltd, 2023) Dineshkumar, G.; Palanisamy, T.Beam-column joints are immensely complicated areas of reinforced concrete constructions. The strengthening of such components can have a significant impact on the earthquake resistant constructions because the rapid collapse of a building could occur if these beam-column joints fail. Recently, designing of reinforced concrete beam-column joints to resist earthquake load becomes more important using ductile design and high strength material. The fibers addition in a concrete directs to an improvement in cracking resistant, ductility, deformation and energy absorption capacity. However, there are currently many distinct types of fibres with various materials and geometric features are used in fiber reinforced concrete to improve the above said properties. The use of basalt fibre, an alternative material made from natural sources that comes from volcanic rock, is the main topic of this essay. The beam-column junction was used to assess the structural behaviour parameters for basalt fibre reinforced concrete, including load–deflection behaviour, ductility, stiffness value, energy absorption capacity, and energy index. From this work, it shows that the natural based basalt fiber shows excellent structural behavior when compared to control concrete. Basalt Fiber Reinforced Concrete (BFRC) has the potential for widespread application in the construction of concrete structures as well as in earthquake-prone regions. © 2023Item COMPARATIVE ANALYSIS OF STRENGTH BEHAVIOURS ON CONCRETE FRAMES UNDER SEVERE EARTHQUAKE LOADS(Scibulcom Ltd., 2023) Balasubramanian, S.; Palanisamy, T.; Senthil Kumar, S.The increase in the development of constructions and infrastructures to compensate the growing population of the world had led to the tremendous demand for concrete. Concrete has been revolutionised by Romans and its use resulted as the finest building material on earth. But as the concrete strength improves, the brittleness increases and as a result the potential for deformation decreases, thus restricting the use of concrete in seismically active areas. Hence, this paper does the experimental research and study of the strength behaviour of reinforcement concrete (RC) and high strength concrete (HSC) effectively. The main aim of this study is to improve the properties of the frame and to withstand the burdens arising from earthquake charges against seismic behaviour. The research analysis includes the design and manufacture with casting and examination of frame speci-mens. The experimental data is checked with empirical results, and the average error percentage is 4.86. The study result showed that HSC infilled frame’s overall load-bearing capability is 4.27 times higher than RC infilled frame, and also 4.48 times higher for HSC bare frame than the RC bare frame. © 2023, Scibulcom Ltd.

Results show that specimen BP3, with 1.2% PVA fiber in PVCC layered beam, and BB2, with basalt fiber fabric wrapped at the bottom up to the neutral axis, exhibit superior performance. BP3 delays first crack initiation, increases the ultimate load-carrying capacity by 19.87%, and achieves a remarkable 54.57% increase in maximum ductility compared to B0. BP3 also demonstrates 54.54% higher stiffness and notable energy absorption. Similarly, BB2 outperforms BB1 and B0 in first crack load, ultimate load carrying capacity, ductility, stiffness, energy absorption, and energy index. BB2 exhibits 2.10 times increase in ductility compared to B0. Incorporating PVA fiber in PVCC layered beams and basalt fiber fabric wrapping offers better improvements in crack resistance, load capacity, ductility, stiffness, and energy absorption, contributing to innovative and sustainable beam design in construction. © 2024, Universidade Federal do Rio de Janeiro.
