This document discusses using recycled industrial materials in roadways. It notes that over half a billion tons of potentially reusable materials are produced by industries each year in the US. These materials can be used as substitutes for raw materials in construction projects like roads and buildings. Some examples of reusable industrial materials mentioned are coal combustion products, construction and demolition waste, used tires, and blast furnace slag. The document outlines environmental, economic, and performance benefits of using these recycled materials in roadways, such as reducing pollution and costs while improving road durability.
Construction and demolition waste recyclingAnand Vallala
Now a days as the construction is increasing the demolition waste from the buildings is also increasing. We have to increase the usage of waste materials and to help for the future generation.
Construction activities generate millions of tonnes of Construction and Demolition (C&D) waste materials each year. These materials contain a lot of reusable materials. If not properly managed, they will become wastes, a burden to the society, which will be extremely expensive to handle and will occupy precious landfill space.
Now even for small projects it has been made mandatory to use Ready mix concrete or compulsory use of Batching plant. However, except for large projects and some industrial projects, Demolition of structures is not yet mechanised. This waste is also affects the air, noise pollution in the form of releasing dust and noise respectively.
Recycling can turn the waste materials into usable products, which can help conserve our natural resources for our next generations and for the sustainable development of the society. In the recent years, C&D waste management issues have attracted the attention from researches around the world.
The ultimate aim is to create the awareness among the Civil Engineers is to do the research on this topic and to reuse these materials.
Main points of this PPT:
• An overview of the concept on Waste management.
• Brief description on “Recycled Concrete Aggregates”.
• Waste reduction and Reuse.
• Demolition techniques.
• Use of proper Waste Management plan.

Behavior of Concrete Using Copper Slag As A Strength Parameter in Low Cost Co...ijtsrd
The value of concrete in present society cannot be underestimated. We can see concrete structures everywhere, such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. Concrete is a composite material which is made up of filler and a binder. Typical concrete is a mixture of fine aggregate sand , coarse aggregate rock , cement, and water. Cement and lime are usually used as binding materials, while the sand binder is mixed as fine aggregates and crushed stones, gravel, broken bricks clinker is employed as coarse aggregates. The concrete having cement, sand and coarse aggregates mix up in an appropriate percentage in addition to water is called cement concrete. In this kind of concrete, cement is used as a binding substance, sand as fine aggregates and gravel, crushed stones as coarse aggregates.An investigation relating to the use of byproducts to enhance the functions of concrete has been about for many years. In the recent years, the researchers have been made to use industry by products such as fly ash, silica fume, ground granulated blast furnace slag, glass cullet, etc., in concrete production and civil applications. The potential uses of industrial byproducts in concrete or as a partial aggregate substitution or as a partial cement substitution depending on their chemical composition and grain size, The utilization of these materials in concrete comes from the environmental constraints in the safe disposal of these products. Big interest is being focused on the environment and safeguarding of natural resources and recycling of waste materials. Various industries are producing a significant number of products which incorporate residues such as reclaimed aggregates, reclaimed asphalt pavement, foundry sand, copper slag, fly ash, glass cullet, polyethylene terephthalate, high density polyethylene HDPE , unplasticized polyvinyl chloride UPVC , plasticized polyvinyl chloride PPVC , low density polyethylene LDPE , polypropylene PP , polystyrene PS , expanded polystyrene UPS .

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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. INTRODUCTION
Each year in the United
States, industries produce over ½ a
billion tons of potentially usable
materials.
Many have chemical and physical
properties that make them valuable
resources when recycled or
beneficially reused, but they are
often disposed of as waste.
These materials can be used as
substitutions for raw materials in the
manufacture of consumer
products, roads, bridges, buildings
and other construction projects.
3. QUESTION??
Each year in the
United
States, industries
produce over ½ a
billion tons of
potentially usable
materials…
What
could be a
usable material??
4. DEFINITIONS
Fly Ash - residue generated in the
combustion of coal
Bottom Ash - non-combustible residue
of the combustion of coal
Aggregate - sand, gravel, crushed
stone, slag
Slag - during smelting, when metals
such as iron, copper, lead or nickel are
exposed to high temperatures,
impurities are separated from the
molten metal and can be removed. Slag
is the collection of compounds that are
removed.
6. REUSABLE MATERIALS
- Coal combustion products (CCPs)
- Construction and demolition (C&D)
materials
- Used tires
- Compost
- Pulp and paper byproducts
- Bottom ash
- Foundry sand
- Reclaimed concrete and asphalt
- Glass
- Roofing shingles
- Blast furnace slag
- Steel slag

- Fly ash
7. WHY USE INDUSTRIAL MATERIALS IN ROADWAYS?
Environmental Benefits
Economic Benefits
Performance Benefits
8. ENVIRONMENTAL BENEFITS
Many industrial materials are used to
replace nonrenewable virgin materials that
must be mined and processed.
Using industrial materials conserves
natural resources and reduces the energy
use and pollution associated with these
activities.
Roads and other structures made with
industrial materials can be more durable.
Maintaining and replacing roads less frequently is
good for the environment because it conserves
natural resources and energy.
Substituting fly ash (a CCP) for cement in concrete
saves the energy and greenhouse gas emissions
associated with producing cement.
9. ECONOMIC BENEFITS
Using industrial materials makes good
economic sense for project owners and
contractors.
Industrial materials are often less
expensive than the virgin materials they
replace.
Recycling or reusing materials onsite can
reduce material hauling and disposal
costs.
Reduces the need for new or expanded
landfills, saving valuable landfill capacity.
The total project bid cost can be
lower, allowing the project owner to
accomplish more work with the same
budget.
10. PERFORMANCE BENEFITS
Asphalt pavement made with used tires is more flexible, quieter and less
prone to cracking than standard asphalt pavement.
Rubber tires used as lightweight fill material offer outstanding long-term
performance benefits and are less expensive than many alternatives.
Using fly ash as a partial replacement for cement in concrete enhances
the durability and smoothness of the concrete.
13. ACTIVITY: FIX THE ROAD GAP
Divide into groups of 2-3
Design the section of the
road (remember the
layers)
Construct a section of road
out of given recycled
materials so that a truck
may pass over
Road must be
compacted, smooth and
dry
The truck must be able to
roll over the constructed
road section only using
gravity as a force
Choose one group
member to explain the
design process
Prizes will be given for
best design and field test
