The document discusses cracks in buildings, their causes and prevention. It classifies cracks as structural or non-structural and by width, direction and appearance. Non-structural cracks are caused by thermal variation, chemical reactions, moisture movement, foundation issues and manufacturing defects. Thermal variation results from temperature changes causing expansion and contraction. Moisture movement from wetting and drying leads to reversible and irreversible movement. After construction, structural cracks can be repaired through epoxy injection, polyurethane injection or stitching cracks. The seminar provides information on identifying crack causes and selecting suitable repair techniques.
Building crack,types,causes & its repairingGAUTAMSWALA
This presentation is all about cracks occur in building.It includes all types of cracks,its major causes and repairing techniques and finally a conclusion from which viewers can fully understand
about building cracks.
A crack is a complete or incomplete separation of concrete into two or more parts produced by breaking or fracturing.
Cracks are one kind of universal problems of concrete construction as it affects the building artistic and it also destroys the wall’s integrity, affects the structure safety and even reduce the durability of structure
Carbon dioxide penetrates into the concrete through the cracks and speed up carbonation around the cracks, thus shortening the structure usage.
The cracks in the concrete wall would cause the leakage of the building; it reduces the stiffness, durability and seismic performance of buildings.
Cracks on the wall surface damage to the later rendering, will affect to the appearance.

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.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

CAUSES & PREVENTION OF CRACKS IN
BUILDINGS

2. About CRACKS
Cracks in buildings are common occurrence. It develops when the stress in a
component exceeds the strength.

6. PRINCIPAL CAUSES OF CRACKS IN BUILDING (Non structural)
Thermal variation
Chemical reaction
Moisture movement
Elastic deformation
Creep
Foundation movement & settlement of soil
Vegetation
Manufacturing defects
Details in next few slides
7. Thermal variation
It depends upon: temperature variation, dimensions, co-efficient of expansion, colour, surface
characteristic, thermal conductivity, insulation, internally generated heat etc.
When concreting is done in summer at high temperature, contraction due to drop in
temperature in winter is high leading to thermal cracks.
When roof in a load bearing structure
undergoes expansion, horizontal cracks occur
in cross walls as shown :
8. To prevent thermal variation cracks:
Provision of expansion joints, slip joints, control joints
Slab should be provided thermal insulation.
Span of the slab should not be large.
Slab should either project beyond the wall or rest only partially on the supporting wall.
10. Moisture Movement:
Reversible Movement
-Material expands on absorbing moisture content
-Shrinks on drying
Irreversible movement
-Material undergo some irreversible movement due to initial moisture change e.g. Shrinkage
of cement on initial drying.
• Initial shrinkage in cement concrete and mortar depends upon: cement & water content,
maximum size-grading-quality of aggregates, duration-method-temperature of curing,
presence of excessive fines in aggregates, humidity, type of cement, temperature of fresh
concrete etc.
12. Control shrinkage cracks:
→ Curing for at least 10 days, drying shrinkage is much less.
→ Presence of excessive silt, dust etc in sand and stone aggregates should not exceed 3%.
→ Shrinkage is much less in coastal areas due to high humidity
→ PPC and low grade OPC have much less shrinkage.
→ The ideal temperature range for concreting is 100C to 300C.
→ Sometimes cracks appear on freshly laid concrete even before it sets. This happens when rate
of evaporation is higher than bleeding. In such circumstances, concrete should be covered
with plastic sheet immediately after concreting and flood cured after initial set has occurred.
13. Measures to Control cracks (before construction)
In structural concrete shrinkage cracks are controlled by using temperature reinforcement.
Even in plain concrete a minimum 0.12% steel is recommended by IS: Codes. It is more effective
if smaller diameter bars- closely spaced are used.
Cracks in masonry can be minimized by using rich mortar and delaying plaster work till
masonry has dried after curing.
Cement plaster richer than 1:6 is harmful for external wall exposed to high temperature
variations, since it will create a stronger membrane than the surface of brick.
Coarse well graded sand should be used for plaster. Fine sand will result in crazy cracks.
14. Measures to Control cracks (before construction)
Strong bond between concrete and plaster prevents shrinkage cracks, if rendering is done as
early as possible after removal of shuttering. Key to plaster is provided by hacking and applying
cement slurry just before rendering
Shrinkage cracks affect the appearance and finish and not the structural stability.
Cracks in walls generally get localized at weak sections, such as doors and window openings or
staircase walls. In external walls shrinkage cracks generally run downwards from window sill to
the lintel of the lower storey.
Construction joint should be avoided in concrete. However if necessary it should be located at
one-fourth of span away from preceding beam.

Polyurethane injection involves a high
pressure (typically 1500-3200 psi) injection
of activated polyurethane through injection
packers hammered into drilled holes.
These fast-setting foams are effective
alternatives for applications involving only
crack sealing (waterproofing) and not
structural repair.
