This document discusses the causes and classification of cracks in buildings. Cracks are caused by external forces like loads or internal stresses from thermal movement, moisture changes, chemical reactions, or corrosion. Cracks are classified as either structural, which can endanger safety, or non-structural, which are cosmetic. Common causes of cracks include thermal variation, chemical reactions, moisture movement, foundation settlement, and vegetation. The document provides examples of different types of cracks and recommends precautions and repair methods to control cracking.

Problems faced by building by moisture or precipitation.pptxKashif390970
Moisture problems occur when excess moisture accumulates or becomes trapped in a part of a building that should be dry. They can happen in just about any building, new or old, and usually occur because of design oversights, construction errors or improper maintenance.
this presentation deals with the different types of cracks generated in concrete during its usage and after its application and also methods to retrofit these cracks
In modern times, they are used to a large extent in the garden or landscaping industry to deal with diverse levels, which may be natural or constructed. Their primary purpose is to maintain pressure and to provide the contents of the filled space with some degree of stability.

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.
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.
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.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
3. INTRODUCTION
3
Cracks in buildings are of common occurrence and are
developed whenever stress in the component exceeds its
strength. This stress may be caused by external forces such
as dead, live, wind, seismic loads and foundation settlement;
or may be induced internally due to thermal movements,
moisture changes, chemical actions, resulting in shrinkage or
expansion of the bricks, mortar, concrete or due to corrosion
of reinforcement etc. render the structure unsafe. The other
causes may be due to fault of structural design.
4. CLASSIFCATION OF CRACKS
# These result from incorrect
design, faulty construction
or overloading and these
may endanger the safety of
a building and their
habitants.
# These may endanger the
safety of a building.
STRUCTURAL CRAKS
# Occur mostly due to internally
induced stresses in building
materials.
# These cracks normally do not
endanger the safety but may
look unsightly, create an
impression of faulty work or
give a feeling of instability.
NON-STRUCTURAL CRAKS
5. CAUSES OF CRACKS
• Thermal variation
• Chemical reaction
• Moisture movement
• Elastic deformation
• Foundation movement & settlement of soil
• Vegetation
6. THERMAL MOVEMENTS
6
• Refers to the expansion and contraction
caused due to temperature changes
• FACTORS AFFECTING
• Temperature variation
• Physical properties of the materials
• Dimensions
• Coefficient of thermal expansion
• CURE : insulation layer, color with
high reflecting characteristics,
using slip and expansion joints
7. LONG SPAN EFFECT IN LOAD
BEARING WALLS
When a beam or slab of
large span undergoes
excessive deflection and
there is not much
vertical load above the
supports, ends of
beam/slab curl up
causing cracks in
supporting masonry;
9. OPENINGS IN LAOD BEARING WALLS
portions of wall marked ‘A’ act
as pillars and are stressed
much more than the portions
marked ‘B’ below the windows.
Thus, as a result of differential
stress, vertical shear cracks
occur in the wall as shown
HEAVY LOADHEAVY LOAD
10. FOUNDATION MOVEMENT &
SETTLEMENT
10
• Shear cracks in buildings occur
when there is large differential -
settlement of foundation either
due to unequal bearing pressure
under different parts of the
structure
• shrinkable clays (also sometimes
called expansive soils) which
swell on absorbing moisture and
shrink on Drying as a result of
change in moisture content of the
soil, are extremely crack-prone
• Cracks that occur due to
foundation movement of a corner
on an end of a building are usually
diagonal
11. VEGETATION
11
Existence of vegetation, such
as fast growing trees in the
vicinity of compound walls can
sometimes cause cracks in
walls due to expansive action
of roots growing under the
foundation.
They also cause dehydration of
soil allowing soil to shrink thus
allowing settlement
12. SOME PRECAUTIONS
12
For shrinkage Indian Standard Code recommends a
minimum reinforcement of 0.25/0.20 percent in the horizontal
direction and 0.15/0 .12 in the vertical direction when using
plain/deformed bars
14. STITCHING
• Quick, simple, effective
and permanent.
• The grout combination
provides an excellent
bond within the substrate.
• Masonry remains flexible
enough to accommodate
natural building
movement.
• Non-disruptive structural
stabilization with no
additional stress
15. CONCLUSION…
This work concludes that though it is impossible to guarantee
against cracking yet attempts can be made to minimize
development of crack. And also, not all type of crack requires
same level of attention. The potential causes of crack can be
controlled if proper consideration is given to construction
material and technique to be used. In case of existing cracks,
after detail study and analysis of crack parameters, most
appropriate method of correction should be adopted for
effective and efficient repair of crack
