RECENT STUDIES ON THE PROGRESS MADE IN MAGNETIC NANO PARTICLES: A REVIEW

Abstract

Numerous uses for nanoparticles have transformed a number of societal fields. Due to its applications in specialist fields including medicine, cancer theranostics, biosensing, catalysis, agriculture, and the environment, magnetic nanoparticles in particular have attracted a lot of attention in the last ten years. The design of multi-functional Magnetic nano particles must include controlled surface engineering if the intended use is to be realized. The Magnetic nano particles have shown to be very effective as biosensors, imaging agents, drug delivery systems, and thermoelectric materials. In this review, we have first briefly covered the primary techniques of MNP synthesis before moving on to their characterisation and composition. Then, using illustrative examples, we examined the possible uses of Magnetic nano particles in various fields. We concluded by providing a summary of the present difficulties and potential futures for Magnetic nano particles. This thorough analysis not only explains the synthesis, functionalization, and use of Magnetic nano particles from a mechanistic perspective, but it also discusses their limitations and future possibilities.

AN EXPERIMENTAL INVESTIGATION ON THE STEEL FIBER CONCRETE BY PARTIAL REPLACEMENT OF TiO2 AND QUARTZ POWDER USING M40 GRADE OF CONCRETE

Abstract

Every construction project in the world uses concrete as a building material. These projects include every conceivable problem in terms of durability, exposure to different reactive substances, and at a position where concrete needs to be high strength. Based on the kind and composition of the elements employed, the concrete is a heterogeneous combination that is intended to solidify and provide strength. In this study, we are doing an experimental examination to see whether the strength of nominal concrete could possibly be increased to become high strength concrete. We used components like steel fibres, TiO2 as a partial cement substitute, and quartz powder as a partial fine aggregate replacement in order to attain this high strength. On materials, freshly-poured concrete, and hardened concrete, we\'ve run a number of tests. We have also examined earlier studies that were conducted on projects similar to this one using relevant materials. We used a variety of material ratios, including 0 percent, 0.5 percent, 1.0 percent, 1.5 percent of TiO2 as a partial replacement for cement, and 10 percent, 20 percent, 30 percent, 40 percent, and 50 percent of quartz powder to replace some of the fine aggregate. We also added 0 percent, 0.5 percent, 1 percent, 1.5 percent, and 2 percent of steel fibres to the concrete

MECHANICAL PROPERTIES OF STEEL FIBER REINFORCED CONCRETE WITH QUARRY DUST

Abstract

Today, concrete is a popular composite material. Coarse aggregate, fine aggregate, binding material and water are the components of concrete. The rapid expansion of construction operations has resulted in a lack of traditional construction supplies. Sand is commonly utilized as a fine aggregate in concrete. The most prevalent source of fine aggregate is river deposits. Natural river sand has become rare and expensive in recent years. If quarry dust is available near the construction site, construction costs can be effectively decreased. Quarry dust can be used entirely or partially in place of river sand. The study\'s notion of replacing natural fine aggregate with quarry dust could increase the consumption of quarry dust created by the quarry.It has been determined that quarry dust can be used as a fine aggregate replacement based on the findings of an experimental inquiry. It has been discovered that substituting quarry dust for fine aggregate at 40% yields the best results. Strength then normal concrete and then decreases from 50%. The compressive strength quantified for verifying percentage and grades of concrete for replacement of sand with quarry dust. This present work is an attempt to use Quarry Dust as partial replacement for sand in concrete along with the steel fibers. Attempts have been made to study the properties of concrete and to investigate some properties of quarry dust reinforced with steel fibers; this article presents the compressive and split tensile strengths of hook end steel fiber reinforced concrete with Quarry Dust. In the experimental work natural sand is replaced by Quarry dust in the proportions of 0%, 30%, and 60%. The hook end steel fibers were used in concrete by 0.5%, 0.75% volume fraction. After conduction of experiments on the cube and cylinder specimens, the results showed that, the incorporation of hook end steel fiber reinforced concrete with 30% Quarry dust for M30 grade concrete.

A MANAGERIAL APPROACH TOWARDS RELIABLE MAINTENANCE OF HIGH PRODUCTIVE MACHINE

Abstract

Energy markets are deregulating rapidly and the price of energy is expected to decrease. Energy suppliers that traditionally operated as regulated monopolies must now find ways to improve their productivity. Energy utilities are typically asset-intensive, so maintenance activities present a potential area for productivity improvement. Reliability Centered Maintenance (RCM) was developed in the commercial aerospace industry approximately 3 decades ago. In the 1980\'s, the Electric Power Research Institute (EPRI) initiated studies for the application of RCM to generating facilities. Recently, EPRI has begun supporting the investigation of RCM methodology in the transmission and delivery of electric power.v

STRENGTH STUDIES OF CONCRETE BY PARTIAL REPLACEMENT OF FINE AGGREGATE WITH SAWDUST

Abstract

This study examines the use of sawdust as a waste product to replace sand and Alccofine (1203) as a partial replacement for cement to alter the properties of concrete. The effects of the alteration on the concrete were investigated after sand was weight for cement in the concrete mixtures. By incorporating sawdust into concrete, waste (sawdust) may be disposed of while also reducing the weight of the concrete. Alcofine (1203) is applied as an admixture to replace cement in various amounts of 0%, 4%, 8%, 12%, 16%, and 20%, while sawdust is added as an admixture to replace fine aggregate in various amounts of 3%, 6%, 9%, and 12%. Compressive and split tensile strengths at 7 and 28 days were taken into consideration for determining the test findings.

STRENGTH CHARACTERISTICS OF FLY ASH BASED GEOPOLYMER CONCRETE WITH 8, 10 & 12 MOLAR NAOH ACTIVATOR

Abstract

Ordinary Worldwide, Portland cement is a vital building component. A source of carbon dioxide emissions alongside deforestation and the use of fossil fuels is the cement making business. The atmosphere is polluted by greenhouse gases like CO2, which contribute to global warming. CO2 makes up roughly 65% of the greenhouse gases that cause global warming. Around 7% of the planet\'s total greenhouse gas emissions come from the cement industry. Alternative binders for concrete manufacturing are required to overcome Portland cement\'s negative environmental consequences. In this work, a geopolymer based on fly ash from Vijayawada with a low calcium content (Class F) was utilised. A thermal power plant was used to create geopolymer concrete.For the activation of fly ash, sodium hydroxide and sodium silicate solution was utilised as an alkaline solution. The ratio of alkaline solution to fly ash was adjusted to 0.45. The sodium hydroxide solution\'s concentration was kept at 8M, 10M, and 12M. (Molars). As ambient curing, several curing conditions for geopolymer concrete were used. At different ages, including 7 and 28 days, the compressive strength and split tensile strength of the geopolymer concrete were tested. According to the test findings, the strength of geopolymer concrete improves along with the alkaline solution to fly ash ratio.

STRENGTH STUDIES ONCONCRETE BY PARTIAL REPLACEMENT OF AGGREGATES WITH GRANITE POWDER AND CERAMIC TILES

Abstract

Due to the day to day innovations and development in construction field, the use of natural aggregates is increased tremendously and at the same time, the production of solid wastes from the demolitions of constructions is also quite high. Because of these reasons the reuse of demolished constructional wastes like ceramic tile and granite powder came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates for making concrete. The ceramic tile waste is not only occurring from the demolition of structures but also from the manufacturing unit. Crushed waste ceramic tiles, crushed waste ceramic tile powder and Granite powder are used as a replacement to the coarse aggregates and fine aggregate. The ceramic waste crushed tiles were partially replaced in place of coarse aggregates by 10%, 20%, 30%, 40% and 50%. Granite powder and ceramic tile powder were replaced in place of fine aggregate by 10% along with the ceramic coarse tile. M30 grade of concrete was designed and tested. The mix design for different types of mixes were prepared by replacing the coarse aggregates and fine aggregate at different percentages of crushed tiles and granite powder. Experimental investigations like workability, Compressive strength test, Split tensile strength test for different concrete mixes with different percentages of waste crushed and granite powder after 7and 28 days curing period has done. It has been observed that the workability increases with increase in the percentage of replacement of granite powder and crushed tiles increases. The strength of concrete also increases with the ceramic coarse tile aggregate up to 30% percentage.

STUDY ON CONCRETE BY USING KENAF FIBRES WITH PARTIAL REPLACEMENT OF CEMENT WITH BAMBOO LEAF ASH

Abstract

BLA was used in place of ordinary Portland cement at weight replacement rates of 0%, 2.5%, 5%, 7.5%, and 10%. The cubes were then crushed to determine the concrete\'s compressive strength at various curing days. The outcome showed that the water cement ratio, total number of curing days, and % of BLA replacement for OPC all had an impact on the workability and strength characteristics of the final concrete. However, it was noted that at 28 days, the results of 10% and 20% BLA were more comparable to the concrete with only OPC. Therefore, it is hoped that this research will serve as a rapid reference for working engineers who will discover BLA to be a good partial replacement for cement in concrete, cutting the cost of producing concrete. adding Kenaf fibre to improve the mechanical qualities of concrete. Compressive, flexural, and split tensile strength tests are performed on M40 grade concrete that has been mixed with various amounts of fibre, including 0%, 0.5%, 0.75%, 1%, and 1.25%, respectively.

STRENGTHENING THE SELF COMPACTING CONCRETE BY RECYCLED AGGREGATE

Abstract

Concrete is the second-most-used substance after water, and more than six billion tonnes of cement are produced each year. As part of the current investigation for new innovations in concrete as well as to decrease aggregate waste, an experimental assessment on self-compacting concrete with varied percentages of coarse recycled concrete aggregate was conducted. The major objective was to investigate the use and effects of coarse recycled aggregate in next generation concretes. The environment is under a great deal of stress as a result of the considerable increase in trash produced during construction and demolition over the past few years, together with the rise in demand for building materials.As a result, the use of recycled aggregate in concrete has been encouraged, which not only enables a more efficient use of natural resources throughout their life cycles but also contributes to environmental protection. This study employs coarse recycled aggregate (RCA) in varying percentage replacements of natural coarse aggregate (NCA) from 0 percent to 100 percent with increments of 20 percent for the production of self-compacting concrete (SCC) of grade 40. Super-plasticizer is applied in order to achieve SCC flow properties at a dose dependent on cement weight. At 28, 56, and 90 days old, testing for split tension and compressive strength were performed on the animals. It has been shown that up to 40% recycled aggregate may be used to create SCC without noticeably decreasing strength and durability.
