Green concrete is an environmentally friendly type of concrete that uses less energy and produces less carbon dioxide during production than traditional concrete. It incorporates waste materials like fly ash, slag, and recycled concrete aggregates to reduce the environmental impact. Using green concrete provides benefits like longer lifespan, lower CO2 emissions, reduced energy consumption, and utilization of industrial waste. It has improved properties such as higher strength, durability, and fire and thermal resistance compared to normal concrete. While green concrete has advantages for the environment and engineering properties, its use is still developing in India due to challenges disposing of industrial waste and higher costs.
The concrete which is made from the industrial wastes and eco-friendly is the green concrete.Green will reduce 10% of CO2 emission which will reduce the global warming, which is one of the reason for world's destruction.Since it is made from the industrial wastes it is very cheap and durable.

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.

Embracing GenAI - A Strategic ImperativePeter 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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
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.

3. INTRODUCTION
• The concrete is made with concrete wastes which are eco-
friendly so called as Green concrete.
• The other name for green concrete is resource saving
structures with reduced environmental impact for e.g. Energy
saving, co2 emissions, waste water.
• Green concrete is a revolutionary topic in the history of
concrete industry.
4. Why Green Concrete ?
– Huge impact on sustainability
– Most widely used material on Earth
• 30% of all materials flows on the planet
– 70% of all materials flows in the built
environment.
• > 2.1 billion tonnes per annum.
• >15 billion tonnes poured each year.
• Over 2 tonnes per person per annum.
5. What is GREEN concrete ?
• Most people associate GREEN concrete with concrete that is
colored with pigment.
• However, it is also referred which has not yet hardened. But in
the context of this topic, green concrete is taken to mean
environmentally friendly concrete.
• This means concrete that uses less energy in its production &
produces less carbon dioxide than normal concrete is green
concrete.
6. Features of Green Concrete
• Cement :-
Most of CO2 in concrete is from the cement
manufacturing process. A typical cubic meter of concrete contains
about 10% cement by weight. Out of all ingredients, cement gives out
most carbon dioxide. The reaction in the process of Cement
manufacture is: CaCO3 = CaO + CO2
• Aggregate :-
Use of virgin aggregates contributes about 1% of all
CO2 emissions from a typical cubic meter of concrete. Therefore, the
use of alternate aggregate is desirable. The use of local and recycled
aggregates is desirable as it can reduce transportation and fuel cost
and support sustainable development.
7. • Resources :-
The growing shortage of natural aggregate and sand is
another aspect the construction industry must consider. While this may
not appear to be a priority topic, pressure from environmentalist and
conservationists worldwide will continue to encourage both legislators
and construction engineers to look for viable alternatives to natural
resources. Use of recycled materials like aggregate, water is some
ingredient which should be encouraged since fresh resources are
becoming increasingly scarce.
8. Materials for Green Concrete
• Locally available: Construction materials, components, and
systems found locally or regionally, saving energy and
resources in transportation to the project site.
• Salvaged, re-furnished, or re-manufactured: Includes
saving a material from disposal and renovating, repairing,
restoring, or generally improving the appearance, performance,
quality, functionality, or value of a product.
• Reusable or recyclable: Select materials that can be easily
dismantled and reused or recycled at the end of their useful
life.
9. Environmental Benefits to using Green Concrete
• Lasts Longer.
• Uses Industrial Waste.
• Reduces Energy Consumption.
• Reduces CO2 Emissions.
10. PRODUCTION OF GREEN CONCRETE
• Concrete with inorganic residual products. Ceramic wastes used as green
aggregates. By replacing cement with fly ash, micro silica in larger
amounts.
• To develop new green cements and binding materials (i.e. by increasing
the use of alternative raw materials and alternative fuels, and by
developing/improving cement with low energy consumption).
• To use residual products from the concrete industry, i.e. stone dust (from
crushing of aggregate) and concrete slurry (from washing of mixers and
other equipment).
• To use new types of cement with reduced environmental impact.
(mineralized cement, limestone addition, waste-derived fuels).
11. Green lightweight aggregates
• Synthetic lightweight aggregate produced from environmental waste
is a viable new source of structural aggregate material.
• The uses of structural grade lightweight concrete reduce considerably
the self-load of a structure and permit larger precast units to be
handled.
• Water absorption of the green aggregate is large but the crushing
strength of the resulting concrete can be high.
• The 28-day cube compressive strength of the resulting lightweight
aggregate concrete with density of 1590 kg/m3 and respective strength
of 34 Mpa . Most of normal weight aggregate of normal weight
concrete is natural stone such as limestone and granite.
12. SUITABILITY OF GREEN CONCRETE IN STRUCTURES
• Reduce the dead weight of a facade from 5 tons to about 3.5
tons.
• Reduce crane age load, allow handling, lifting flexibility with
lighter weight.
• Good thermal and fire resistance, sound insulation than the
traditional granite rock.
• Improve damping resistance of building.
Speed of construction, shorten overall construction period.
13. ADVANTAGES
• Optimized mix designs mean easier handling, better consistency and
easier finishing.
• Reduction in shrinkage & creep.
• Green Concrete uses local and recycled materials in concrete.
• The heat of hydration of green concrete is significantly lower than
traditional concrete.
• This result in a lower temperature rise in large concrete pours which is
a distinct advantage for green concrete.
14. Improved engineering properties
• Mix can result in a reduced paste volume within the concrete structure
resulting in a higher level of protection against concrete deterioration.
• Higher strength per kilogram of cement.
• Increased durability & lower permeability.
• More aggregates typically mean higher Modulus of elasticity.
15. LIMITATION
• By using stainless steel, cost of reinforcement increases.
• Structures constructed with green concrete have comparatively
less life than structures with conventional concrete.
• Split tension of green concrete is less than that of conventional
concrete.
16. SCOPE IN INDIA
• Green concrete is a revolutionary topic in the history of
concrete industry.
• As green concrete is made with concrete wastes it does take
more time to come in India because industries having problem
to dispose wastes.
• Also having reduced environmental impact with reduction in
CO2 emission.
17. CONCLUSION
• Green concrete having reduced environmental impact with
reduction of the concrete industries co2 commissions by 30%.
Green concrete is having good thermal and fire resistant.
• In this concrete recycling use of waste material such as
ceramic wastes, aggregates, so increased concrete industry use
of waste products by 20%. Hence green concrete consumes
less energy and becomes economical.
• So definitely use of concrete product like green concrete in
future will not only reduce the emission of co2 in environment
and environmental impact but also economical to produce.
