In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.
Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong.[6] In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.

Utilization of industrial waste in the construction industryeSAT Journals
Abstract Utilization of industrial waste in construction industry. This experimental work is an effort to try to develop the awareness & importance of industrial waste management & its utilization in productive manner among the people. In today’s more environmentally-Conscious world, a more responsible approach to the environment is to increase the use of by-products of one industry which is disposed off as waste as raw material for some other industry. Developed countries have made rapid strides in the utilization of supplementary Cementitious material in cement & concrete. Lack of awareness Consumer preferences, negatives marketing strategies & Lot of miss-understanding among the people have impeded their utilization in our country. In this work I have chosen three industrial wastes for blending with Portland cement Viz. Fly ash, Blast furnace slag & waste of glass industry. All these three waste after grinding properly were blended with ordinary Portland cement in different proportions. Then that of blended cement was tested for various properties of cements such as Fineness, Standard Consistency; Soundness, Setting time & Compressive Strength. As all these three wastes in powder form are of cementitious materials, they are proved to be best when blended with Cement. I have got improved results related to most of the properties of cement as compared to that of ordinary Portland cement. All these wastes prove the slogans true that are “ash to cash” or “refuse to resource” & “wastes to wealth”. In our country annually huge quantities of wastes are produced by the industries. Instead of disposing off these wastes if they are utilized in such a manner then it will provide an eco-friendly Solution, simultaneously solving the problem of pollution. So such waste can be blended with Cement, is the step towards economy & obviously towards progress of the nation. Keywords: - fly ash, ground blast furnace slag, waste glass powder; experiments on blended cement with different proportions of wastes; cost comparison.

Uncertainty in Improving Durability Aspects and Mechanical Properties of Bamb...IJARIIT
The construction industry is the main consumer of energy and producer of carbon dioxide in the present global world. The production of one ton of steel emits more than two ton of carbon dioxide whereas production of one ton of bamboo consumes more than one ton of carbon dioxide from the atmosphere. With the ever increasing population and in country like India where 80% of the population live below poverty line, there is a great need of some other suitable material in terms of cost, availability and environment friendly. In this regard many researchers in the past has emphasized on the use of Bamboo as reinforcement. Bamboo offers competitive strength to mass ratio. Since it is a natural material, the necessity to understand their long term behaviors regarding its acceptance by people in general is very important. Due to the advantageous characteristics of bamboo, efforts should be made to publicize the use of bamboo.

The idea of using bamboo as possible reinforcement has gained popularity. Bamboo, as a fast growing renewable material with a simple production process, is expected to be a sustainable alternative for more traditional structural materials, such as concrete, steel and timber. The diminishing wood resource and reduction in natural forests, particularly in the tropics, have focused world attention on the need to identify a substitute building material that should be renewable, environment friendly and widely available. The tensile strength of bamboo fiber can be comparable to that of steel, and the average fracture toughness of bamboo can be higher than that of aluminum alloy. Bamboo grows at rapid rates, it almost grows to its full size in a few months and finishes developing within five years. Bamboo is the world’s fastest growing woody plant. It grows approximately 7.5 to 40cm a day, with world record being 1.2m in 24 hours in Japan. Bamboo grows three times faster than most other species. Commercially important species of bamboo usually mature in four or five years in time.
Uncertainty in Improving Durability Aspects and Mechanical Properties of Bamb...IJARIIT
The construction industry uses the most of clean energy and also produces most of the carbon dioxide in the present global world. The production of one ton of steel and concrete emits more than two tonne and one tonne respectively of carbon dioxide whereas production of one tonne of bamboo consumes more than one tonne of carbon dioxide from the atmosphere. In SAARC countries like India where about two-third of the population live below poverty line, there is a great need of some other suitable construction material in terms of cost, availability and environment friendly. Towards this, many researchers in the past has emphasized on the use of Bamboo as reinforcement. Bamboo offers competitive strength to mass ratio, compared to re-bars. Since it is a natural material, the necessity to understand their long term behaviour regarding its acceptance as a suitable construction material in general is important. Due to the advantageous characteristics of bamboo, efforts should be made to popularize the use of bamboo.
In this study, a review of the existing research work on Bamboo Reinforced Concrete with the emphasis on the various factors, which are considered as demerits in making bamboo reinforced concrete construction, as a tool is presented. This uncertainty study may serve the goal of making the dream of common people, to have their own home, come true.

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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

1. Introduction
Cement and steel are two of the most used materials in the current infrastructure
industry. The production of both of these materials involve complex processes and
requires a huge initial investment. Moreover, the production of these two materials need
2. 2/6
power and degrades the environment. An alternative is required in developing countries
where a power crisis prevails.
The above-said problem has led to various researches to find the economical,
environment-friendly, easy to produce and locally available material. Bamboo is one such
alternative that satisfies all the shortfalls of steel. The bamboo uses 50 times lesser energy
than steel for the same amount of production.
The bamboo is a type of perennial grass that grows naturally and has sufficient strength to
support light loads. It is found in diverse environmental conditions across the globe.
Bamboo is an ideal material to be used in low-cost projects where the structure has a
lower strength requirement.
The bamboo grows taller and rapidly as compared to other plants. Their structure is
hollow cylindrical with nodes. The use of bamboo minimises energy consumption,
pollution, consumption of fossil fuels and promote renewable resource usage.
2. Bamboo as Reinforcement Material in Concrete
2.1 Strength
The bamboo has a high strength to weight ratio that makes it suitable to be used as a
construction material. It has strength comparable to hardwood.
Bamboo is orthotropic in nature. They have high strength in the direction parallel to the
fibres and low strength perpendicular to the fibres respectively.
The physical and mechanical properties of bamboo vary with the moisture content
present. Higher moisture content results in weaker strength and higher weight. Generally,
the moisture content should be lesser than 15%. Only well-dried and treated bamboo
should be used for structure and reinforcing works.
The following table compares the bamboo with concrete and mild steel-
Strength Parameter Comparison
Bamboo may have tensile strength as high as 370 MPa. In some cases, they can be used as
tension members replacing steel. The tensile strength to weight ratio of bamboo is six
times greater than that of steel. However, it should not be confused as bamboo has a
higher tensile strength than steel.
3. 3/6
Modulus of Elasticity to Density Ratio
Bamboo outperforms steel and concrete when compared in terms of Young’s Modulus and
density. The following graph shows the performance of other materials in comparison to
bamboo.
The stress strain curve for bamboo shows its’ brittle nature-
Stress Strain Curve for Bamboo
2.2 Durability
An untreated bamboo may last up to 2-6 years and up to 1 year when exposed to water.
Moreover, it is susceptible to termite attack and rot (fungus) if left untreated. The curing
of bamboo, when cut at the grove, reduces the starch content and makes it lesser prone to
the insect attack. On the spot, curing can be done by smoke, immersion or heating.
The moisture present in bamboo affects durability. Higher the moisture, lesser is
durability. The bamboo can be dried in open air, greenhouse or heating.
The durability also depends on the method of preservation used.
2.3 Other Uses of Bamboo in Construction
Bamboo is used as a building material for scaffolding, pedestrian bridge, building
construction, and reinforcing material.
4. 4/6
In China and India, bamboo has been extensively used for suspension bridge
constructions since ages. Japan commonly uses bamboo for fencing, grates and gutters,
fountains and decorative works. In the Philippines, Nipa Hut is a type of hut made of
bamboo.
Bamboo flooring and furniture is also available in the market.
What uncommon/innovative use of bamboo have you seen? Let me know in the comment
below.
Pedestrian Suspension Bridge made up of Wire Ropes and Bamboo
3. Limitations of Bamboo-
3.1 Insect Attack-
Termite and beetle attack make bamboo lesser durable. Due to shell structure, a small
deterioration equal to shell thickness can lead to considerable change in strength.
Insecticide like boric acid can be used on bamboo.
3.2 Swelling & Shrinkage
Swelling and shrinking are one of the biggest limitations of bamboo. The change in the
size of bamboo due to moisture variation and/or temperature leads to a weaker bond
between concrete and bamboo leading to failure in pull-out condition.
When untreated bamboo is used as reinforcing material, it absorbs curing water and
expands. Post curing period the bamboo shrinks to its original size and leaves the void
between itself and concrete. This limitation can be overcome if bamboo is treated with
water-repellent material.
3.3 Low Fire Resistivity
Bamboo is very much prone to fire. However, it can be made somewhat fire-resistive by
applying fire retardant like borax.
3.4 Lower Strength compared to Steel
Nowadays, high yield strength steel bars are in use which have yield strength as much as
30 times of bamboo. Thus, for similar loading condition bamboo to be used is 30 times of
steel that will make the structure bulky.
3.5 Unsuitability for the Earthquake Resistant Structures
Bamboo is brittle in nature and cannot be used as reinforcing material in the earthquake-
resistant structure.
5. 5/6
4. Bamboo Reinforced Concrete
As the demand for low-cost alternatives of steel is increasing the research in this field is
also increasing. Bamboo has been tried and tested as reinforcing material in concrete and
has given satisfactory results but still bamboo reinforced concrete is still in the early stage
of research before being used at a large scale.
4.1 Beams-
Researches have shown that for the beam of size 3.4m x 0.12m x 0.3m (free span- 3m)
when reinforced with 3% bamboo increased ultimate applied load by 400% as compared
to beam without reinforcement.
4.2 Slabs-
In, Brazil bamboo reinforced slabs are being made successfully. Half bamboo diaphragms
connected with bamboo rod close to the diaphragms passing through bamboo diameter is
used in the slab. The formwork used is the permanent type. This arrangement of bamboo
prevents the shear failure of the slab and also provides sufficient bond.
The absence of the connector rod leads to shear failure as diaphragm alone is insufficient
to sustain the shear stress.
4.3 Columns-
When 0.3m diameter circular columns reinforced with 3% bamboo (with bonding agent)
and permanent bamboo formwork were tested, the results of such column were similar to
the steel column of the same size. Thus, it can be said that the bamboo reinforced columns
are as good as steel-reinforced columns.
4.4 Behaviour of Bamboo in Bending Stress-
The behaviour of bamboo reinforced concrete is still a matter of research as the failure
occurs mostly due to tensile failure of concrete and bamboo even when the beams were
over reinforced. The problem arises due to imperfect bond between the concrete and the
bamboo.
5. Sustainability-
The industrial processes have become more eco-friendly with a focus on reducing
pollution and preserving the environment. The bamboo provides a sustainable
alternative.
The production of 1 ton of cement and 1 ton of steel emits more than 1 ton and 2 tons of
carbon dioxide respectively. The production of 1 ton of bamboo consumes more than 1 ton
of carbon dioxide.
6. Future of Bamboo Reinforced Concrete
6. 6/6
In Singapore, to make a composite material bamboo has been combined with thermoset
polymer resin under pressure. The said material has given satisfactory results. The tensile
strength is around 400 MPa, compressive strength 100-120 MPa, bending strength 200
MPa and modulus of elasticity 50 GPa. Moreover, the process is carbon dioxide negative.
The Maharashtra Public Works Department have included bamboo in State Schedule
Rates for 2020-21. This step will further help in popularising the bamboo as a
construction material.
