Abstract. Clay soil is usually stiff in dry state, but in wet state, it loses its stiffness and becomes softer. Various types of clay minerals have unique characteristics of low bearing capacity and certain compressibility. Especially Montmorillonite clay mineral exhibits more degree of swelling and shrinkage and loss of strength when moisture added. According to recent research, rice husk ash is a potential improving material based on its pozzolanic activity. In this study, to improve the engineering properties of expansive clay the admixture such as fly ash and rice husk ash will be added in different percentages as 5, 10, 15 and 20. For the laboratory test that includes atterberg’s limits test, standard proctor compaction test and unconfined compression test were conducted on locally collected expansive soil with various percentages of these two stabilizers in order to examine their influences. The maximum values of Unconfined Compressive Strength were obtained corresponding to 15% Rice Husk Ash and 20% Fly ash.

Abstract. Due to industrialization and man-made activities in and around the world, Day by day pollution levels are drastically increasing. This being said, building materials in the present context can be produced using novel techniques by applying advanced pollution reduction coatings/strategies. The self-cleaning and de-air polluting concept is emphasized in concrete structures using nanotechnology. Photo-catalytic treatment will be a promising approach as it alleviates structural and aesthetic damages on building materials. Finally, the risk exposure due to pollutants can be computed for better treatment of the same.

Abstract-In reinforced concrete structure beam, the beam column joints are more crucial zones which are most susceptible to failure during earthquake excitation. It is very important to design the joint to dissipate the large amount of energy to the neighbouring elements without loss of strength and ductility. Several retrofitting methods are employed to strengthen the beam column joint. The effective method one among is Fibre Reinforced Polymer (FRP) composites. In this paper, the deflection of beam column joint wrapped with aramid fibre has been calculated and it is compared with Ansys software solution. From the results, the deflection of the joint is decreased when aramid fibre is used.

Abstract. Topology Optimization (TO) is the method used for maximizing the performance of the system by optimizing material arrangement inside an appropriate topology design operation, for an appropriate set of loads, boundary restraints, and constraints. This helps in the reduction of the materials which in turn reduces the cost of materials. In the current scenario, the price of the ingredients of the traditional concrete is very high. The implementation of TO gives a good impact on the economy of construction, as the materials are optimally placed in the plane of load distribution as per various loading condition. The Evolutionary Structural optimization (ESO) is used for topology optimization. The main merits of implementing topology optimization are that the cost, as well as the weight of the structural member, becomes more effective. Customarily MATLAB software is used for analysis and designing the member. This method will highly useful for the society and the environment.

Abstract. 3D printing also commonly known Additive manufacturing (AM) is the layering of materials by a computer to build 3D shapes of desired materials. It's very handy for prototyping and working with geometrically complicated materials. It was founded and developed in the 1980s, but it was a costly and demanding procedure at the time, with few uses. It became quiet relevant and inexpensive in the 2000 and a variety of applications which includes product development, component manufacturing, and tool manufacturing, plastic, aerospace engineering metalworking, Foot wear, dental and medical applications, and electronics. Even the household uses of 3D printers were happening. The construction sector also started using 3D technology and the systems used were called 3D printers for construction Computer-aided design, or CAD design, or the usage of a 3D scanner are both used to build a 3D model.

Abstract. In general, CLSM mixtures contain common ingredients such as Portland cement, fly ash, good mixing and water. CLSM is forced to fill in the back material and not low-strength concrete, rather it can best be described as property which is designed as concrete and strength flow and strength as per requirement and used as a backfill to avoid soil issues. CLSM can be built with a variety of strengths and sizes, taking into account costs future requirements, low power CLSM will be required to allow future excavation, and if there is no space for future digging the energy can be high on the other hand, furthering the size of CLSM can be adjusted according to the cost and material requirements. However, some industrial products and recycled products are also accepted and promoted as long as they are available, costing a particular use and the necessary characteristics of a combination such as flow, power, extraction, and quantity are acceptable. The aim of this study was to test whether it was possible to apply red mud such as placing a portion of Portland cement in a low-power controlled (CLSM) component made of industrial-grade products. The control mixture was initially made from the Portland cement, fly ash, and water. Bleeding, flow, the initial time for the setting of new CLSM compounds is measured and subsequent complications include compression. Results-They performed well and complied with CLSM requirements at ACI 229 levels in terms of flow, bleeding rate, initial set-up time, uncompressed compression strength. Low power control devices (CLSM) remove the problems of ground receding to provide the strength of the supporting structure.

Abstract. Concrete is well known for its binding nature and Compressive strength. However, the tensile strength of the concrete is not so sufficient. Hence to improve the tensile nature and to enhance the flexibility in concrete steel rod is introduced as reinforcement. The rebar provides sufficient flexural strength to the concrete. Thus, the reinforced concrete is used in construction for its ease of access and long life. The major issue and problem faced by the rebar in concrete is corrosion which leads to reduction in the strength and age of the structure. The main objective of this research is to provide the protection for steel rebar against corrosion which improves the life of the structure. Many researchers worked on this to find a solution for corrosion. Corrosion inhibitors is one among the best method which helps us to protect the steel against corrosion. The pomegranate fruit which is highly antioxidant can fight against corrosion. An extract was obtained from pomegranate peel powder which can act as an organic inhibitor is used in this research. The inhibitor opted for this study is cheap, economic and renewable since it is organic. In this project the steel was coated with PPE extract and tested in different environment conditions and the efficiency of corrosion control was obtained with impressed voltage current. The result was compared with conventional uncoated rebar. The result proved that PPE is a good natural inhibitor for the steel, and the efficiency of the inhibitor is good enough to resist the corrosion in the rebar.

Abstract. Many different types of wastes are being generated on a daily basis which includes household waste, industrial waste, hazardous waste, construction and demolition waste etc. This generation of waste has increased enormously, and it needs to be considered as a prominent problem, as the waste management and waste disposal is not being done properly. Thus, it will lead to environmental degradation and pollution. On the other hand, over utilization of materials for construction activities leads to its extinguishing. Both scenarios will pose a threat to the environment. So, this study is carried out by utilizing vermicompost as a replacement material for red soil in the manufacturing of clay bricks. Initially, the physical properties of the raw materials are studied and the brick specimens are casted by varying vermicompost at 5, 10, 15 & 20% for red soil and they are tested for compressive strength, water absorption, loss on ignition. Among the replacements done, 10% of vermicompost for red soil gave higher strength to the bricks which is 6.23 N/mm2 higher than the control specimen. The water absorption for all the trials is found to be less than 20% as per IS 3495 part 2. The loss in weight of the bricks due to ignition is less than 15% for all the specimens manufactured. Therefore, the utilization of vermicompost will reduce the waste disposal considerably and also the cost of the bricks can be minimally reduced as waste is being incorporated in it.

Abstract. Construction industry is estimated to consume nearly 30-35% of natural resources and associated to major global pollutions. It is essential to move our path into a sustainable way of construction practices, to conserve natural resources for the future generation. Several researchers had investigated the various possibilities of alternatives to produce sustainable green building materials from industrial by-products, for example, blast furnace slag, fly ash and silica (SiO2). Presently, there has been an attempt to use the large amount of Sugarcane Bagasse Ash (SBA) which is formed when using the bagasse-biomass fuel in electric generation industry. Due to availability of Cement kiln dust (CKD) and Sugarcane Bagasse Ash (SBA) in large amounts, it appears to be cost effective and eco-friendly by the applications for these industrial by-products. The overall goal of this research study was to replace cement by certain percentage through potential applications for the Cement kiln dust (CKD) and Sugarcane Bagasse Ash (SBA) based on a detailed characterization of the materials. The analyses are discussed in terms of Setting time, Consistency test and Compressive Strength. As a result, Sugarcane Bagasse Ash (SBA) for a certain percentage replaced in cement increases the strength of mortar cube but if it exceeds 20%, then the strength starts to decrease.

Abstract. Additives are ingredients and chemicals that are mixed into concrete to improve its fresh state and change its properties. The majority of admixtures are sold as chemical compositions on the market. These chemical admixtures are exceedingly costly and harm the environment significantly. Adding admixtures to concrete, on the other hand, is not a new notion; it has been used and developed in numerous countries in the past. In this project, we are investigating the possibilities of using natural materials like "Terminaliachebula” (Kadukkai). Terminalia chebula extract is added in different concentrations of 2.5%, 5%, 7.5% to the cement concrete, and its effects on the workability and strength of concrete are studied. Terminalia chebula when added to cement mortar does not affect however, it improves workability while also increasing compressive strength by 1.832 times of reference concrete. But the initial setting time of concrete is increased by 30 minutes of nominal OPC concrete.
