EXPERIMENTAL INVESTIGATION ON BEHAVIOR OF SHEAR WALL ASSEMBLED WITH INTERLOCK...IAEME Publication
This study describes the development of a new type of interlocking concrete
masonry block to reduce weight based on topological optimization and new design
pattern of experiments. The Concrete block wall is easily stacked and placed.
Interlocking mortar less concrete block wall system was developed as a new structural
component for masonry building construction. The interlocking mortar less block
system will reduce the time and cost of construction. A new pattern was designed for
Interlocking concrete block acting as the load bearing wall system is different from the
block units are interconnected through the interlocking block. Hollow concrete blocks
are produced to achieve the reduction in weight and to improve strength. The concrete
blocks were shaped by certain design pattern which can align horizontally and
vertically. Experimental done results obtained structural behaving well under
compressive load.

Types of Materials:
Bricks
1. Hollow Blocks
2. Green Bricks
Making & Use
Differentiate green bricks for the materials they are constructed and there are several proposals (in line or already in progress) of bricks with different components:
Coal ash: This was an idea of a civil engineer, Henry Liu, in 1999, with a double environmental benefit. With this material the bricks are obtained at 212 degrees in 10 hours and take advantage of 45 million tons of the waste generated by coal power plants.
Hemp and straw: This brick and green has been used by Spanish companies. Despite the apparent fragility of the material hardness is similar to conventional ones. They have the disadvantage of being more expensive but well isolated from the outside temperature. This represents a savings of energy expenditure for heating and air conditioning, so that pays the price soon.
Used plastic and peanut shells: ecological bricks of this material are a creation of the Experimental Center for Economic Housing in Argentina who says they are tough, lightweight insulation and economic. In addition to producing energy savings possible recycling of waste for production.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
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.

Concrete block
1. PRESENTATION ON
TYPES OF CONCRETE
COURCE TEACHER : FARJANA RAHMAN
SUBJECT : CONSTRUCTION WORKSHOP
NAME : KAMRUL HASSAN
ID : 05505622
2. What is concrete ?????
Concrete is a composite material composed of aggregate bonded together with a fluid
cement which hardens over time. Most use of the term "concrete" refers to Portland
cement concrete or to concretes made with other hydraulic cements, such as cement
foundation.
5. Precast concrete is a construction product produced by casting concrete in a
reusable mold or "form“
which is then cured in a controlled environment, transported to the construction site
and lifted into place.
ADVANTAGE :
In contrast, standard concrete is
poured into
site-specific forms and cured on site.
Use: façade
Precast concrete
6. 2.Poured Walls
Poured concrete walls can be used for a foundation, retaining wall or decorative wall. First
the forms need to be put up and reinforced for the liquefied concrete to be poured into. For
smaller jobs, concrete can be mixed in a small portable mixer or even in tubs or pails. For
larger walls and foundations, the concrete is usually trucked in for pouring. You need to do
this in weather that is conducive to the curing and setting of concrete
USE : foundation, retaining wall or
decorative wall
DISADVANTAGE :This type of wall
is expensive and time consuming
to construct.
7. 3. Block Walls
Concrete block walls can be used for foundations and retaining and decorative walls
also. They come in different shapes and sizes for different jobs and designs. These
blocks are pre-made in a factory and shipped to the site where the wall will be built. The
wall is constructed in a brick-laying fashion, with mortar put between blocks.
ADVANTAGE :This type of
concrete wall is one of the more
inexpensive and less time
consuming ways to build a wall.
USE : foundations and retaining
and decorative walls also.
8. 5. Stucco Walls
A stucco concrete wall is a thin layer of concrete that goes over an existing wall. This
not only allows for coverage of cracks and chips, but it also adds texture to the wall. This
is an inexpensive way of giving a wall the look of concrete. The stucco material can be
put on in patterns that swirl, crisscross or go straight up and down.
USE :over an existing wall
ADVANTAGE : This type of
material is easy to work
with and can withstand the
coldest and hottest of
weather.
9. Stamped concrete walls are becoming popular. The stamping is done using the
poured concrete technique, with the forms molding the concrete in the shapes of
stones or masonry patterns instead of as smooth panels. The resultant wall can look
remarkably like stone or brick, which adds a natural rustic look to the wall you are
constructing.
6. Stamped Walls
USE : poured concrete technique
ADVANTAGE :This technique is less
expensive and takes less time than
building a stone or masonry wall.
10. 7. Colored Walls
•Colored concrete walls are available in all the poured concrete techniques and some of
the pre-made panels. This works especially well with the stamped concrete in the shapes
of stones, giving them a more realistic coloring. Many colors are available in addition to
the options for the natural colors of stone and brick.
ADVANTAGE :This coloring
technique allows you to deviate
from the plain chalky look of
traditional concrete.
USE ; pre-made panels.
11. 8. Concrete retaining walls
ADVANTAGE : Many codes require a permit
for any structure that holds back what amounts
to thousands of pounds of earth, and most limit
the height of an amateur-built retaining wall to
3 feet.
12. ADVANTAGE OF CONCRETE WALL
•providing functional support for keeping soil in place,
•preventing sink holes and eliminating the eye sore of dirt piles and hills
•helpful in preventing flooding
•reduces maintenance and prevents erosion
