Nanotechnology is the field of applied science the theme of which is the control of matter on an atomic and molecular state. It’s basically the manipulation of matter on a nano scale. It’s an enabling technology that allows us to develop materials with improved as well as new properties with a vast range of applications. Nanotechnology has a vast application in the field of engineering, especially in the field of civil engineering. A vast number of building material can be enhanced by the use of this technology, for example: Concrete, Steel, Wood and Glass.
Concrete is a building material, a nanostructure multiphase composite material that age over time. It’s composed of an amorphous phase, nanometer to micrometer size crystals and is bound by water. Nanotechnology modifies the molecular structure of concrete material and improves its properties. The nanoparticles used in concrete are CARBON NANO TUBES (CNT), NANO-SILICA, TITANIUM DIOXIDE (TiO2), etc. 1) The Carbon Nano Tubes are added in small amounts; 1% by weight of the cement. This small quantity improves the mechanical properti...

Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures

Today, the used concrete is called Portland cement; so, the process to produce Portland was an initiative of Joseph Aspdin in the early 1800’s in England who, through its marketing process, in report to the good quality of the stone built with Portland, allowed people to favorably compare concrete made with his cement to the popular building stone. So, concrete is a porous material, whose properties depend on its pore space. Several kinds of pores exist in accordance with the concrete mixing process, ranging from the air voids that are entrapped in this mixing process, which can be quite large, up to a few mm in diameter, to a capillary pores, as being essentially

Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...

Understanding Nanotechnology: A Comprehensive Overview
1323 Words | 3 Pages
“Nanotechnology is science, engineering, and technology conducted at a nanoscale which is about 1 to 100 nanometers,” according to the National Nanotechnology Initiative. A nanometer is a billionth of a meter, there are 25,400,000 nanometers in an inch and a sheet of newspaper is about 100,000 nanometers thick. Putting that into perspective, if a marble were a nanometer, a meter would be the size of the Earth. Nanotechnology can be used throughout all fields of science, including chemistry, biology, physics, materials science and engineering to study and apply extremely small things. Physicist Richard Feynman introduced the concepts of nanoscience and nanotechnology with his talk titled “There’s Plenty of Room at the

Fundamentals of Building Construction: The Concrete
1653 Words | 4 Pages
Concrete is a composite material used widely in the construction industry. Concrete is basically a mixture of cement, water, aggregates and admixture (sometimes). Cement is a fine gray powder that consists of oxidizes calcium, silicon and aluminum. The aggregate used is normally gravel, crushed stone or sand. Admixture is a solid or liquid substance that gives a certain characteristics of the concrete. The cement reacts with water chemically and binds the aggregates together through a process called hydration during hardening or curing of concrete. It means that water helps in the hardening of the concrete while the cement bind the aggregate and also react with water to form a solid mass.

The Pros And Cons Of Nanotechnology
839 Words | 2 Pages
Nanotechnology has been a groundbreaking new field of science for years now introducing many new forms of materials stronger, lighter, and more durable than any others before. Nanoscale particles in many things such as the polymer materials for baseball bats, tennis rackets, motorcycle helmets, and power tools can make them work harder than people ever thought, but just like many other things, the better it seems the more consequences it has the potential to have. With all the positives to nanotechnology there will always be a negative, but if regulated correctly can we lessen the downsides of it? Nanotechnology, though it may have a profitable and useful place in the future of our world, how can we engineer it and put it to good use without badly impacting the environmental and the health of people through the advance of it.

Advantages And Disadvantages Of Fly Ash
750 Words | 2 Pages
Fly ash is a by-product of coal from power stations. It helps to improve the durability of concrete. Through the observation under the SEM test, It can be noticed that the fly ash sample consists of almost regular spherical or cenospheres particles ranging 2 um to 14 um in diameter (Ismail et al., 2007). This is due to the fact that fly ash is produced by fusing small and light particles that remain suspended in the burning chamber but are captured afterwards by electrostatic filtration equipement (Rivera et al., 2013). The huge particle size of fly ash enables it to be ball mill again in order to reach a smaller particle size. Based on past research, the binding of OPC with fly ash increases the compressive strength due to the denser

Essay On Bioconcrete
1013 Words | 3 Pages
Abstract: Concrete is used as a construction material in structures since the days of Roman and Greek civilisations. Now it is one of the most used construction material on the planet. In present day almost every structure is made of concrete. Therefore its performance under loading is quite important. Concrete structures are very susceptible to cracking and repairs as well as maintenance of concrete structures due to cracking are difficult and very expensive. As a possible solution to this problem, considerable interest has been directed presently towards the introduction of self-healing materials in concrete. Here, attention is focused on different healing approaches including encapsulation techniques and Bioconcrete.

The durability of cement paste
710 Words | 2 Pages
The durability of cement paste is one of the most topical field nowadays that economic restraint and conservation will remain the rule of the day. The term "degradation" means that the cement paste fails to serve the intended purpose for the length of time expected. It should be noted that normally, cement paste often does have an essentially indefinite life span, in the absence of degradation processes [32].

Composites Essay
774 Words | 2 Pages
Particle-reinforced composites move into two divisions which are large particles and dispersion-strength. Large particles go under the condition which the contact between particle-matrix cannot be treated on the atomic or molecule level, whereas a different way such continuum mechanics is used. The filler used for particle-reinforced composites usually alternate the properties of the material or could substitute some of the polymer volume with cheaper material. In this case, the smaller and the more evenly spread throughout the matrix the particles are, there is an increasing of effective reinforcement. A good example of a large-particle composite is concrete [1]. In the other hand of particle-reinforcement composites, the dispersed particles are considered small which allows...
