AIM: The aim of this topic is to define fiber reinforced concrete and its application, it important properties as well as it superior resistance to cracking. As a result of the ability of fiber to arrest cracks, the composites of fiber possesses an increased in tensile strength both at the first crack and at ultimate, especially under flexural loading, and the fibers can still hold the matrix together even after a lot of cracking. Introduction Concrete is a structural material that is weak in tension
ABSTRACT Concrete is a composite material composed mainly of water, aggregate, and cement. The desired physical properties of the finished material can be achieved by including additives and reinforcements in the mixture. Generally, fibers used in concrete are to control cracks, shrinkage and to reduce permeability. Fibers also show excellent resistance towards impact and abrasion. SIFCON (slurry infiltrated fiber reinforced concrete) is one of the recently developed construction material. It is
Fiberglass reinforced concrete (GFRC) is most suitable for construction because it is a great material for restoration of old buildings and also used for the exterior of the buildings. It is also being used widely for walls and ceilings. GFRC allow almost perfect replication of building terra-cotta and ornaments. It’s very low shrinkage allows molds to be made from existing structural ornamentation, then cast in GFRC to replicate the original designs. GFRC is lightweight compared to other traditional
The industrial age brought with it creative freedom. Production in this time was on an unseen scale and saw the proliferation of new construction materials; reinforced concrete, steel, and glass. These materials were experimented with, manipulated, and used to create all sorts of structures that would have been impossible using older methods of construction. The use of these new materials lead to the iconic structures recognizable the world over. The towers that were erected during the 19th century
The usage of concrete was explored by the Early Christian and Roman architects but fell out of use throughout the Middle Ages and Renaissance period. The material was only fully explored again in the later half of the 19th century but only for mundane purposes where the material was cheap, easy to work with, and versatile, but most importantly it’s fireproof characteristic. In 1870, the idea of reinforcing the concrete was born; steel rods were to be inserted to increase its strength. Taking this
current technology. It is the search for an architecture that is meaningful within its context and at the same time participates in the more universal aspects of a contemporary mobile society.” (Matter. F.S: 1989) In this essay I will discuss how concrete regionalism was presented in the work of Le Corbusier who is the most classic example of this movement, Oscar Niemeyer, and Antoine Predock . With each architect having a highly individual vision that has created unique buildings for people and their
entrance). This second entrance could be used as an access point for large machinery and for delivery of materials and equipment onto the site. Structural Make-Up The basement is excavated by using permanent embedded retaining walls formed using concrete secant piles around the perimeter and excavating the soil in between. The secant piles remain as a structural component of the building. The basement floor slab is cast-in-situ with integrated pad foundations to support the cast-in-situ columns supporting
Statement of purpose “Education is the most powerful weapon which you can use to change the world.” I would like to start by going back to the initial days of Engineering where I was not sure about doing Engineering but as the days passed I started realizing the step that I took could not have been better .I was fascinated by the laboratories and field work of Civil Engineering and my interest for the subject started growing .Moreover, I had always had to believe that education which cannot help
by creating an aesthetic out of structure and seeking alliance with an industrial world. At the B... ... middle of paper ... ... solution of a central core and columns made the structure safe and efficient. The concrete also acted provided security against uplift because of concrete nature of heaviness. Mechanical systems were engineered within the floors which allowed for more spatial freedom. The efficient solution to the foundation was also achieved through engineering and the use of caissons
After graduating with predicate “very good” in 2011, I seized the opportunity to put all the theories and applications I learned in university into action by working as a structural engineer. As part of my work, I have designed both steel and reinforced concrete structures such as industrial warehouse, residential housing and retail store. Every task I faced during my work demands myself to continually improve my design quality and makes me aware of the future challenges in my career. These, along with
calculations those were based on standard codes of practice & submitted to head of design for approval. The design should be cost-effective and meet all the architectural requirements. This project entailed using my geotechnical engineering knowledge, reinforced concrete design knowledge and construction
Le Corbusier is a world famous architect, writer and urban planner whose ideas and designs have shaped the way we see architecture today. His eccentric ideas and devotion to bettering the downfalls of urbanization are what led to his five decades of fame in the architectural community. Below is the story of how he became known as what he is today. Le Corbusier was born in a small town in Northwest Switzerland Known as La Chaux-de-Fonds on October 6th, 1887. Le Corbusier was born Charles-Eduard
CHAPTER 2 LITERATURE REVIEW 2.1 General This chapter provides a literature review spanning the range of the complex biology of bamboo for understanding to prior research conducted on mechanical behavior and different applications of bamboo. 2.2 Design Provisions Technical documents describe the benefits, uses, and equations for structural materials. A structural codebook for bamboo does not exist, but the first manual for bamboo design was published in 2000 with the ICC‟s technical document titled
supplies, “Use of synthetic fibers for reinforcing concrete is continuously, increasing. The increase has been considerable since 1980, but slowed somewhat in 1990, a year of substantial construction cutbacks. Apparently the construction community believes there are advantages in the use of synthetic fibers in concrete.” (Schupack) Synthetic fibers are used to improve crack control in concrete. Some reports say that synthetic fiber reinforced concrete (SFRC) would replace welded wire fabric in many
Concrete is an extremely versatile and durable building material. Concrete can be used to build long lasting structures even in very harsh environments when it is made with adequate constituents and mix design and properly handled .performance problems that may arise occasionally are often due to the use of materials that do not full fill minimum quality requirements, unsatisfactory specifications or due to inappropriate construction methods. A concrete consists of sand, coarse aggregate
As we know nowadays concrete plays an important in civil engineering field. Use of concrete has also overcome the brick masonry. Concrete is mixture of cement, aggregate (fine and course), water and chemical admixture is also added when needed. About 75% of total concrete material is acquired by aggregate. So, it is important to choose the right type, quality and quantity of aggregate. The main matrix of concrete is made by aggregate. The aggregate particles are bounded with each other by cement
workability is medium which makes it suitable for producing normal reinforced concrete. The results also shows that the more water/cement ratio in the mixed concrete, the better the workability as slump increases from 45 to 51mm after extra 200ml of water is added. Curing Curing allows hydration of concrete to take place as it provides water supply to ensure concrete stays saturated. Under saturated condition, water filled space in concrete could be replaced with cement paste and
Conventional concrete structures are reinforced with non prestressed and prestressed steel. The steel is initially protected against corrosion by the alkalinity of the concrete, usually resulting in durable and serviceable construction. For many structures subjected to aggressive environments, such as marine structures and bridges and parking garages exposed to deicing salts, combinations of moisture, temperature, and chlorides reduce the alkalinity of the concrete and result in the corrosion of
The success of architects is defined not so much by the problems they face as the act of their creative and practical responses. Located in once the bombarded Berlin, a new language of architecture emerged. It appears with multiple contradictions, yet not confliction, from itself to the surroundings and within its own construction. That is the Berlin Jewish Museum, submitted by the young Daniel Libeskind in a competition to provoke the unsavory history of Berlin very soon after the fall of the Berlin
CHAPTER I 1.1 Introduction Formwork is defined as temporary structure whose purpose is to provide support and containment for fresh concrete until it can support itself. It moulds the concrete to the desired shape and size and controls its position and alignment. The development of formworks is parallel with the growth of concrete construction throughout the 20th century. The advancement of technology, increase of population and the space limitation lead the way to construct high-rise buildings.
