Geopolymer bricks contain fly ash as the source material and an alkaline activator for the activation of polymerization reaction.experimental work is supposed to be performed on geopolymer bricks with fly ash and GGBS as source materials and sodium hydroxide and sodium silicate as an activator. It reduces dead load on structures due to light weight (2.6 kg, dimension: 230 mm X 110 mm X 70 mm).
Cellular Lightweight Concrete is also known as CLC. In other words, CLC is also known as foamed concrete. The CLC is widely used for construction purposes as it has various advantages and usage than the traditional concrete bricks.
The foamed concrete is manufactured from mixing of Portland cement, sand, fly ash, water and performed foam in varied proportions. This CLC (Cellular Lightweight Concrete) can be produced at building sites with the use of machines and molds used for normal concrete.
One of an important characteristic of foamed concrete is it has self-compacting property as there is no compaction is required. And also, it easily flows out from the pump to fill the mold. With this property is can be pumped to maximum distance and height.
For continuous cellular lightweight concrete is manufactured by mixing light mortar and preformed foam under pressure in a special static mixer.
Popular as Building material.
Material with adhesive and cohesive properties.
To bind the fine and corse aggregate together.
Common variety of cement is known as the Portland cement.

The alkali-aggregate reaction (AAR) occurs when alkalis, typically sodium and potassium ions from cement, reacts with minerals present in aggregates within concrete.This reaction can lead to the formation of a gel, which can induce swelling and exert pressure on the concrete, ultimately resulting in the expansion and, in severe cases, the cracking of the structure. The detrimental consequences of this reaction become more pronounced over time, potentially compromising the structural integrity of the concrete.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.

2. Blended cement
• Blended cement are produced by inter-grinding
Portland cement clinker together at temperatures
of about 1400–1500°C.)
• The dominant materials used for blended cement
are BFS, fly ash and silica fume.
• ASTM C595 provides prescriptive-based
specifications for specifically blended cement
that consist of portland-cement clinker ground or
blended with suitable proportions of granulated
blast-furnace slag or natural or artificial
pozzolans.
3. Advantages of blended cement
• Improves the workability of fresh concrete, making it easier to place and
finish. Using less water also reduces shrinkage and permeability.
• Contribute to the long-term strength gain of concrete. Silica fumes can
hasten strength development and reduce curing time.
• Lower heat of hydration and less risk of thermal cracking
• Reduces heat of hydration and thermal stresses.
• Reduced overall concrete cost:
• The mineral supplements used to replace portland cement require
significantly less processing and typically lower the cost of the concrete.
5. Type IS (X), Portland-Slag Cement
• Higher level of compressive strengths in concrete
when compared to OPC
• Higher flexural strength to concrete, which
enhances its structural stiffness and minimises
load deflections
• Reduces the ingression of harmful substances
such as chlorides and sulphates due to low
permeability
• Environment-friendly due to reduced GHG
emissions
6. Type IP (X), Portland-Pozzolan Cement
• High compressive strength
• The application includes masonry mortars and
plastering
• Protects concrete against alkali-aggregate
reaction
• Makes the concrete more impermeable and
denser
7. Type IL (X), Portland-Limestone Cement
• Portland-limestone cement (PLC) is a blended
cement with a higher limestone content, which
results in a product that works the same,
measures the same, and performs the same, but
with a reduction in the carbon footprint of 10%
on average.
• Increases durability
• Excellent placing and finishing properties
• Shrinkage and heat of hydration improved
• Enhanced setting and strength performance
8. Type IT, Ternary Blended Cement
• High strength
• Corrosion resistance
• ASR resistance
• Elimination of thermal cracking
• Low permeability
• Sulfate resistance
9. Applications
• Major engineering projects
• Domestic construction
• Precast concrete
• Stabilisation including pavement recycling for
road construction
• Mining applications
• Specialist formulations such as adhesives,
renders, mortars and grouts
10. Conclusion
• The growing use of supplementary
cementitious material blended portland
cement is due in part to numerous
performance factors, including low
permeability, resistance to chlorides and
sulfates, mitigation of alkali-silica reaction,
greater strength, lower temperatures for mass
concrete, and improved workability.
