Composite materials are formed by combining two or more materials with different physical properties to produce a new material with superior properties to the original materials. Reinforced concrete is a composite of cement and steel that is stronger, harder, and more resistant to forces than either material alone. Fiber optic cables transmit data through thin glass fibers and are used for telecommunications due to their high data capacity and low interference.

Autoclaved aerated concrete (AAC) block is a building material made of Portland cement, fine aggregates (fly ash or sand), water and an expansion agent in an autoclaving process heated under pressure which results in the production of air voids in the material, making it less dense, easy to cut/mould and better insulating
It is special type of concrete that can take the bending stresses.
It consist of special type of materials that makes it flexible. It was developed by the Professor Victor Li at the University of Michigan.
Its engineering name is Engineered Cementitious Composite (ECC).
It exhibits the property of a ductile material instead of a brittle material which is shown by the conventional concrete.
This material can bring the revolution because of its some special quality such as flexibility, self-healing, lighter weight, etc. In some countries such as Japan, Korea, U.S.A, etc the flexible concrete is used in many structure.
But in India it is still a new material and requires proper research for its use in India.
Soon we may saw the use of flexible concrete in many structure.

Transparent concrete is a concrete based building material with light-Tran missive properties due to embedded light optical elements usually Optical fibres. Light is conducted through the stone from one end to the other. Therefore the fibres have to go through the whole object. Transparent concrete is also known as the translucent concrete and light transmitting concrete because of its properties. It is used in fine architecture as a facade material and for cladding of interior walls. In this paper, to integrate the merits of concrete and optical fibre, for developing transparent concrete by arranging the high numerical aperture Plastic Optical Fibres (POF) or big diameter glass optical fibre into concrete. The main purpose is to use sunlight as a light source to reduce the power consumption of illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an architectural purpose for good aesthetical view of the building.
A crisp and concise presentation on bendable concrete.
In this presentation introduction, ingredients, uses, advantages, disadvantages, environment friendliness of ECC are explained.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. The Meaning of Composite Materials
• A composite material is a structural material formed by combining
two or more materials with different physical properties, producing a
complex mixture.
• In the making of composites, components are combined to form new
type of materials that can overcome the limitations of the original
material.
• Composite materials are comprised of two phases:
a) Continuous phase (base)
b) Dispersed phase (matrix)
3. • Composite material produced will have different properties far more
superior to the original materials.
• Composite materials are:
The Meaning of Composite Materials
Harder
Lighter
Stronger
More resistant to heat and corrosion
Made for specific purposes
4. Components
• Component:
a) Concrete
b) Steel • Is strong in tension (high tensile strength)
• Corrodes easily
• Using thick steel columns to support a heavy load is expensive
• Components: a mixture of sand and small stones bound by
cement.
• Is strong in compression, brittle and weak in tension.
• Cannot withstand vibrations.
• Will crack under the action of bending forces.
• Concrete pillars must be big to support heavy load; takes up a lot
of space.
5. Reinforced Concrete
• Reinforced concrete is made by adding the concrete mixture of
cement, water, sand, chips and small stones into a frame of steel
bars or steel wire netting. When set, a composite material is formed.
6. Reinforced Concrete
• Reinforced concrete is a stronger building material as it combines the
compressive strength of concrete and tensile strength of steel.
• It does not corrode easily.
• It is relatively cheap.
• Can be molded into any shape.
• Can withstand very high applied forces (high pressure) and can
support very heavy loads.
7. Uses of Reinforced Concrete
• Framework for highways
• Bridges
• Oil platforms
• High-rise buildings
• Dams
8.
9. • Existance of resistance causes the loss of electrical energy as heat
• Resistance increases as temperature increases.
• Can conduct electricity with zero resistance when they are cooled to extremely
cold temperatures. (transition temperature- using liquid helium)
• it conducts electricity without any loss of energy
10. • Ex. When Copper (II) oxide (CuO), barium oxide (BaO) & yttrium oxide (Y₂O₃) is
heated up, a type of ceramic with the formula (YBA₂Cu₃O₇), is produced ,known
as perovskite / YBCO, which can attain superconductivity at 90K(-183°c)
• Metal oxides are electric insulators, however when combined to form a
composite, it is a superconductor that can conduct very high current over long
distance without any loss of energy.
• Used to make more efficient generators, transformers, electric cables, amplifier,
computer parts, stronger & lighter electromagnets.
11.
12. • Bundles of glass tubes with very small diameter, finer than human hair & are
very flexible
• Composite material that can transmit electronic data/signals, voices & images
in a digital format, in the form of light along the fibre glass tubes at a fast speed
• Consists of a core of glass of higher refractive index enclosed by a glass cladding
of lower refractive index. A light wave entering the fibre will travel along the
glass tube due to total internal reflection.
13. • In the field of telecommunication,
1. Used to replace copper wire in long distance telephone lines, mobile phones,
videos, cameras and etc.
2. Carry more data (higher transmission capacity) with less interference
3. Higher chemical ability
4. Lower material cost
5. Can send signals faster than metal cables
6. Occupies less space
14. • In the field of medicine
1. Laser beam can be chanelled through the fibre optics in operations to remove
unwanted tissues
2. Used in endoscopes(used to examine the internal organs)
• Used in instruments
1. To inspect the interior of manufactured products.
15. • Fibre glass is obtained by adding a polyester resin (a type of plastic) to molten
glass. It cannot be compressed easily and is more tensile than the original
materials.
• Fibre glass is light, withstands corrosion, can be cast into different shapes, is
impervious to water, not very flammable, not brittle and stronger than even
steel.
• It is used to make racquets, construction panels, electrical appliances, pipes,
and water tanks.
16.
17. • Produced by embedding photochromic substances like silver halides in glass and
adding a little copper (i) chloride
• When exposed to UV rays, silver halides decomposes to form silver and halogen
atoms
• The silver deposited darkens the glass
• The photochromic glass become clear again when light intensity is lowered
2AgBr 2Ag+Br₂
18. • Silver atom and bromine gas recombine by reacting with copper ion
• Used for making camera lens, car windshields, and information display panels
