 Abstract

The strength and durability of concrete after casting changes at variance factors regarding physical and chemical damages Concrete structures with steel-reinforcement are in a continuous and losing life with corrosiveness that naturally occurs from long-term exposure to an aggressive environment. The concrete structure like dams, canals, bridges which have the influence of water forms various types of chemical reactions which include carbonation attack, sulphate attack, chloride attack, alkali aggregate reaction etc. Chemical reactions, either intrinsic or extrinsic, are one of the main reasons for concrete's deterioration. The present dissertation consists on an analysis of the chemical expansive reactions in concrete element, the alkalis aggregate reaction, and the internal sulphuric reaction. During the carbonation process the fundamental element identified in the concrete microstructure is calcite which comes outs at the surface of concrete structure, in the form of cracks. When carbon dioxide causes by environment come contact into the concrete structure and effect with calcium hydroxide to create calcium carbonate this phenomenon is called as carbonation. Carbonation usually describe by pH value which indicate the depth of reaction in the structure. The depth of carbonation directly affects the life of structure in year. Through the years to overcome this problem the solution is being discovered by performing various experiments on Concrete after and before the casting. Which gave us the Chemical test like by increasing the C02 binding capacity, improving CaO Value and physical tests such as applying epoxy coating, etc.? After all, performing the various types of test for particular outcome finally check for durability tests for concrete structure is take place for better result. There are many of them but in this case it will be pH indicator, UTM and CTM is being discussed. This project addresses the study of chemical reaction which is taking place on various type of concrete structures and affect the durability and strength of it.

 Abstract

Bridges are structures that connect two places or two points separated by natural bodies like sea, ocean, hills, etc. These bridges are mainly constructed for different vehicles to move on but even pedestrians can also use. In West Bengal there are many bridges but among them four major ones are: Howrah Bridge, Second Hooghly Bridge, Bally Bridge and Nivedita Bridge. All these four bridges serve as the lifeline for the entire state. This paper deals with the overview and case study of Howrah Bridge and Second Hooghly Bridge; their history, constructional details and materials, impact on social, economical and cultural life, etc.

 Abstract

Growth in construction industry is linked to the growth of infrastructure sector and the building industry. Construction industry has been growth @10-12% per annum. Concrete is widely used as a construction material due to inherent advantages. The demand for granite aggregates only expected to grow as the demand for infrastructure is ever increasing. Hence, there is a pertinent need to look for alternate materials to granite aggregates. This study explores use of ceramic tile waste as an option to the replacement of granite aggregates in terms of suitability. In this study the ceramic tile waste is being used to replace the granite aggregate i.e., coarse aggregate (CA). The ceramic coarse aggregate (CCA) is used in concrete by replacing CA by 25%,35% and 45%. To compare the results of conventional concrete (CC) with CCA concrete a concrete design mix of M20 is produced with various proportion of CCA material. Due to the good bounding nature of ceramic material with cement it increases the strength of concrete. From the study it is found that the percentage of replacement of CA with CCA material is 45%, within which the performance of concrete is better, and all the results attained within the designed limit.

 Abstract

One of the most dreadful disease is breast cancer and it has a potential cause for death in women. Every year, death rate increases drastically due to breast cancer. An effective way to classify data is through classification or data mining. This becomes very handy, especially in the medical field where diagnosis and analysis are done through these techniques. Wisconsin Breast cancer dataset is used to perform a comparison between SVM, Logistic Regression, KNN and Decision tree algorithm. Evaluating the correctness in classifying data based on accuracy and time consumption is used to determine the efficiency of the algorithms, which is the main objective. Based on the result of performed experiments, the support vector machine shows the highest accuracy (96.6%) with the least error rate. ANACONDA Data Science Platform is used to execute all the experiments in a simulated environment.

 Abstract

Containerization is the way toward bundling a software with all of its essentially required runtime-libraries, frameworks and system-configuration files so that it can be executed proficiently in a variety of computing environments [1]. Containers do not put a strain on the system, requiring only the bare minimum of resources to operate the solution without the need to replicate an entire operating system. Since the program requires less resources to run, it can run a greater number of applications on the same hardware, lowering costs as compared to virtual machines which require separate guest OS for isolating the environment for the program libraries. Docker is one of the platforms for containerization and has many orchestration programs for the efficiency. This paper focus on the different algorithms proposed for allocation of resources and talks about their results obtained.
