The document discusses green or eco-friendly concrete as an alternative to traditional concrete. It states that green concrete reduces the environmental impact of concrete by using less energy in production and emitting less carbon dioxide compared to normal concrete. Some ways green concrete achieves this include using industrial waste and recycled materials as ingredients, and optimized mix designs. Green concrete provides benefits like longer lifespan, reduced emissions and energy usage, without increasing costs. It can also improve engineering properties and durability compared to traditional concrete.

It is a seminar Report on the Topic of Autoclaved Aerated Concrete Bricks (AAC).This is a brick which is not a clay brick, it is a brick whose main constituent is Fly ash and cement. This seminar report is Prepared by a B.Tech Student of final year of Civil Engineering, pursuing B.tech from Abdul Kalam Technical Institute, Lucknow.
In this report the student tries to give a brief knowledge about the Concrete brick and its present life Exploration with cost analysis and merit demerits.
Concrete is a major waste in construction Industry. It needs to be recycled to make a waste free environment. So how concrete is recycled, which type of concrete can be recycled, where it can be used is mentioned in this ppt.

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.
It is all about sustainable buildings or green buildings and a brief study of some sustainable building materials we can use for making a building sustainable and green.
Papercrete is a construction material which consists of re-pulped paper fiber with Portland cement or clay and/or other soil added. First patented in 1928, it was revived during the 1980s. Although perceived as an environmentally friendly material due to the significant recycled content, this is offset by the presence of cement. The material lacks standardisation, and proper use therefore requires care and experience. Eric Patterson and Mike McCain, who have been credited with independently "inventing" papercrete (they called it "padobe" and "fibrous cement"), have both contributed considerably to research into machinery to make it and ways of using it for building
The geopolymer cement is formed by polymerization process which involves the reaction between an aluminosilicate source material such as fly-ash, GGBS, etc. with an alkaline activator solutions.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Concrete is a composite construction material made
primarily with aggregate , cement, and water
CONCRETE
3.
concrete is the second most consumed entity after
water it accounts for around 5% of the world‘s total
CO2 emission
Carbon dioxide is one of the green house gas which
is responsible for global warming
IMPACT ON ENVIRONMENT
DUE TO CONCRETE
1. Green house gas emission
4. The main ingredient in concrete is cement and it consists of
Limestone (Calcium Carbonate CaCO3)
During manufacture of cement, its ingredients are heated to
about 800 - 10000C.
During this process the Carbon Dioxide is driven off
CaCO3 CaO + CO2
Approximately 1kg of cement releases about 900gms of
Carbon Dioxide into the atmosphere.
5. Major ingredient in the production of concrete is
aggregates without aggregates it is impossible to
produce concrete
Aggregates are mined from the rock mines and the rate
with which concrete is produced there will be
significant reduction in naturally occurring materials.
2.Reduction in naturally occurring materials
6. 3.Disposal of construction and demolition waste
Disposal of construction and demolition waste has
become a major problem these days
According to the report of Technology, Information,
Forecasting, Assessment Council the total amount of
waste from construction industry is estimated to be 12
to 14.7 million tons per annum
Out of which 7.8 million tons are concrete and brick
waste.
Because of increasing problems of these wastes many
countries have started researches to use these materials
as source

The use of lightweight concrete provides structural
efficiency and economic advantages.
It helps in reduction of the dead load, increases the
progress of the building, and lowers haulage and
handling costs
relatively low thermal conductivity
LIGHT WEIGHT AGGREGATES
15.
Structural Light Weight Aggregate Concrete is a
concrete having 28 day compressive cement strength
more than 17 MPa and 28 day air dried unit weight
not exceeding 1850 kg/m3.
The concrete may consists entirely of light weight
aggregate or a combination of light weight
aggregate and normal weight aggregates
Use of air-entrainment will greatly improve the
workability, and the tendency for bleeding in the
light-weight concrete.

This cement is based on an intermediate product, clinker,
which is produced with minor additions of mineralizes to
the kiln..These mineralizes are Calcium Sulphate (CaSO4)
and Calcium Fluoride (CaF2).With the addition of these
mineralizes, the energy consumptions are reduced by 5%.
Also the CO2 emissions get reduced. It is found that there
is a 5-10% increase in 28-day strength of the cement
GREEN CEMENT
