Application of Smart Material in Structural Engineering

Anubhab Panigrahi

With the development of materials and technology, many new materials find their applications in civil engineering to deal with the deteriorating infrastructure. Smart material is a promising example that deserves a wide focus, from research to application. With two crystal structures called Austenite and Martensite under different temperatures, smart material exhibits two special properties different from ordinary steels. One is shape memory, and the other is super-elasticity. Both of these two properties can suit varied applications in civil engineering, such as prestress bars, self-rehabilitation, and two-way actuators, etc.

One of the main objectives of the research is to investigate the application of smart materials in civil engineering by focusing on the literature review, basic information collection, and basic mechanic properties of smart materials. In axial tension tests, the force- extension curve and stress-strain curve of shape memory and superelasticity materials were measured separately. These curves verify the research of forerunners.

Four beam experiments were conducted to evaluate the performance of flexure beams with superelasticity material as reinforcement bars. Load-displacement relationship at the midspan, strains on the surface of the concrete beam, and cracking width for different loads were measured.

This research is just the first step in the investigation of the application of smart materials in structural engineering. Some bigger beams are prepared for experiments in the near future.

Marble powder is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. The marble industry inevitably produces wastes, irrespective of the improvements introduced in manufacturing processes. In the marble industry, about 50 to 60% production waste. These waste create many environmental dust problems in now a day to day society. In requiring a suitable form of management in order to achieve sustainable development. In this paper explained about the behavior of concrete with partial replacement of cement with added percentage values of marble powder and attain required strength. Partial replacement of marble powder in cement accordingly in the range of 20%, 30%, 40%, by weight for M20 grade of concrete. With this experimental research work the problem of waste production management of this agro waste are will be solved. It analyzed the research work the compressive strength, flextural strength, split tensile strength values at 7, 14, 28 day. The test results show that the compressive strength, split-tensile strength and flexural strengths are achieved up to 30% to 40% replacement of cement with marble powder without affecting the characteristic strength of M20(1:1.5:3) grade concrete.

KEYWORDS: Cement (53 grade), Marble powder, Fine aggregate (M-sand), Coarse aggregate (20mm size).

Red Mud is a hazardous waste generated in the Bayer process Alumina production (AL2O3) from Bauxite ore which contains high levels residual alkalinity and toxic heavy metal. Therefore, Red Mud is a hazardous waste of Alumina Industry. The volume of Red Mud which generated in the alumina processing plant depends on the quality of crude Bauxite ore, may be greater than the volume of alumina 1-1.5 times. The alumina processing plant usually disposes liquid Red Mud into reservoirs, which cause the risk of major environment pollution for lowland. The particle dimension of red mud usually less than 1mm . Therefore, dry red mud easy spread into the air and causes dust pollution. It is often exposured to dust cause skin and eyes diseases. Red mud in an liquid state causes harmful effect to human skin. Composition and properties of red mud in the world have been presented by many researchers in their publications.

Fly Ash is a byproduct of coal-fired electric generating plants. The coal is pulverized and blown into burning chamber for immediate combustion. Heavier ash particle (Bottom Ash or Slag) fall to the bottom burning chamber and the lighter ash (fly ash) fly out with exhaust gas, thus the term fly ash. Before leaving the stack, these fly ash particle are removed and collected by electrostatic precipitation, bag houses or other methods.

The Rivers form a city’s lifeline and no other city in the country can boast of having three Rivers running through it. Karha riverfront in Baramati City is a multifunctional riverfront with majority of premises being used as Residential, Irrigation,Indusrial Recreational purposes.

The water quality of the Karha River is very low due to a large amount of untreated sewage being let into the river. Other major problem pertaining to Karha river is flooding of the river.

The project work aims to carrying out suitable river-training works and measures to reduce the river pollution, restore and maintain the river ecosystem as well as riparian ecosystem.

The aim of this project would be transform Baramati as a unique cultural platform with recreational and entertainment facilities serving the city.

This project deals with the statistical investigation of air quality and climatic change in chennai. The analysis ofambient air quality in chennai city employing Air Quality Index (AQI). An Air Quality Index has been proposed for the city of chennai for pubic information and data interpretation. The average concentration for four major parameters are taken into account (SO2,No,Co,PM2.5) for the year 2016-2017(present day) for specified location in chennai city is taken . The place is Alandur which is an industrialist area. The AQI is calculated using AQI procedure. It has been observed that the air quality before varadha cyclone is in satisfactory zone, whereas now, it has reached moderately polluted condition. The climatic change also varies from the past year to the present.

Keywords: Air Pollution, Air Quality Index, Particulate Matter CO& PM2.5, SO2.
