Recommended: Importance of construction materials
Throughout the construction industry, technology plays a role to help ease the completion of a project to all of the parties involved. The amount of technology application in the industry supports the belief that technology has a positive impact on project productivity. One of the main materials used in the construction industry that surrounds us every day, in which we overlook, is concrete. Concrete is an art form, in which it takes time and talent in order for it to be used efficiently, to produce its high strength and longevity. However, the downfall of this material is that it is extremely costly and nearly impossible to form it to an aesthetically pleasing surface. In spite of this, what if I told you that there is hope? That the dream of a material made of concrete, producing the same qualities, can be formed to any shape, and used anywhere was a reality.
Concrete Canvas (CC) was designed by British engineers in the early 2000s as part of a design competition hosted by the British Cement Association (www.nationalgeographic.com, 2013).
The engineers had hopes to design a way to make efficient shelters quickly. In order to do that, they had to develop a material that could be dried in thin layers, wetted in an uncontrolled method then, set without cracking, into a dependably strong form, thus, creating Concrete Canvas (www.nationalgeographic.com, 2013). One of the first applications of Concrete Canvas was by the British Military. They used the product to protect sandbags in Afghanistan. It was found that with the protection from CC, the sandbags were now able to stop on average 1,100 machine gun rounds fired into it (www.nationalgeographic.com, 2013). After seeing the ease of use of the material and its characteristics, the en...

...ckage, and like a child’s balloon, the shelter will inflate (www.youtube.com, 2011). Once the shelter is inflated, completely saturate the shelter and with less than an hour of time, you have completely installed your shelter (www.youtube.com, 2011). After 24 hours the shelter will be completely useable and you will have one completely hardened, fireproof, waterproof, and sterile shelter.
Concrete Canvas is a relatively new technology that I believe, with more research and development, could change the construction industry completely. Concrete Canvas has such a positive impact on a construction project by lowering cost, time, and labor compared to typical mixed concrete. With the ability to form to almost any shape, in any condition, and be used in almost any building application I ask, “Do you think Concrete Canvas is an impressive industry changing technology?”
Another successful commission was the design for Cerritos Center for the Performing Arts as seen in Figure 2. This was commissioned in 1993 in Southern California. In this project, she worked closely with RoTo Architects. German had been sought- after for her expertise in color, surfaces and materials. She is known for this piece for the materials and color applied to the buildings interiors, exteriors, and campus. With this building she included the design of exterior tiles and other architectural elements and printed pieces.
However, the success of the building schemes relied on the construction methods and innovations that are now attributed as bei...
If the ancient Roman innovation of concrete, were to not have been significant, it would not have continued to be used across the globe. In fact, ancient Roman hydraulic cement-based concrete was so notable that modern day scientists are trying to, “replicate the exact formula for which ancient Roman concrete was made.” This is due to ancient Roman concrete being so sturdy and strong that aspects of it have lasted over 2000 years without deterioration. Without the innovation of Roman concrete, many of the modern world’s infrastructure would not be stable, causing havoc across the globe. Also, advancements in construction, health, and even safety areas would not be possible, as almost every piece of infrastructure, from sewerage and water pipes, to building and security walls, would not be able to remain as safe to use. This is because the modern world relies so heavily on concrete, with around five billion tonnes of concrete being used around the world each year,becoming the single most widely used material in the construction industry. In fact, around 76% of all first-world infrastructure is reinforced with concrete. Without this substance, much of the modern-world's infrastructure would not be as tall or sturdy as what it currently is, as it would simply deteriorate or break. Hydraulic cement-based concrete is certainly the most significant Roman
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 principle, Ernest Ransome (America) and Francois Hennebique (France) both developed frame systems. From this, open plan workspaces with large windows were created and it was proved to be well accommodated where fire had previously been a danger. Hennebique’s system used slim vertical posts, thin parallel beams on brackets and floor slabs; this resulted somewhat like a timber frame. Concrete was one of the most flexible materials and one with a least determining form. Concrete relied on its mould and the intelligence of its designer to give it aesthetic qualities for one to appreciate it. This became much more obvious when the architects of the last 19th century attempted to discover a style based on this material.
In order to create innovative public architecture, considered to be the most civic, costly, time intensive and physical of the arts, the project holds a degree of risk, strife, and negotiation . Overcoming these tasks and creating worthy public architecture is a challenge designers try to accomplish, but are rarely successful. The people involved in a potential public building, can be larger than the building itself. Public architecture tries to please all, even the doubters and critics, but because of the all these factors, a building is closer to failing than succeeding.
In this report, we will introduce and illustrate on precast concrete, pre-stressed concrete, ready-mix concrete, reinforced concrete, terrazzo and Urbanite in details.
First produced in Sweden in 1923 and used in the UK since the 1960s (when they were known as ‘cellular’ or ‘gas’ concrete blocks), aerated concrete or ‘aircrete’ blocks are the lightest of the family
The works of Le Corbusier, Oscar Niemeyer and Antoine Predock shows a high level of honour and truthfulness. These architects were concrete revolutionalists, they partially over-turned the concepts of ‘purism’, ‘less is more’ and functionalism with the plastic freedom made possible by reinforced concrete.
Concrete is Artificial Stone obtained by mixing cement, sand and aggregates with water. Fresh concrete can be molded into almost any shape which is an inherent advantage over other materials.
This class has examined the various accomplishments of ancient Rome, many that have been carried on throughout time and influenced numerous cultures around the world. Amongst those accomplishments were the development of concrete and the utilization of arches. This paper will examine the Roman development of both concrete and the infamous concrete arch that is utilized in many modern day structures today.
These ultimate ones built numerous concrete structures, such as the Pantheon in Rome, a great expression of the finest of Roman architecture that survives until today with 42 meters-diameter dome made of poured concrete. So, the concrete’s name was coming from the Latin “concretus” which means to grow together. Effectively, like the chemical hydration process, which after hours and days being the material growing together from a viscous-elastic, moldable liquid into a hard, rigid solid. Because of the hardness of concrete, we cannot imagine modern life without thinking about it. Nowadays, approximately, five billion tons of concrete are used around the world each year, with a yearly approximation of one ton for each person (400 liters per person).
‘Necessity is the mother of invention’, goes the adage. Such is the story of Self-Compacting Concrete, whose invention materialized out of an urgent need. Increasing the durability of concrete structures was Japan’s major concern in the 1980s (Okamura & Ouchi, 2003). Japan faced a severe shortage of skilled workers in its construction industry, and compaction of concrete had to be performed by skilled workers to ensure durability of the concrete structures. Therefore, the development of self-compacting concrete that could fill every space of the formwork by virtue of its own weight without the need of mechanical vibration seemed a very promising alternative. This would also eliminate noise sensitivity, white finger syndrome and other environmental and biological inconveniences that resulted from the vibrations on site (De Schutter, 2007). The concept of SCC was first pr...
Concrete is composite consisting cement, aggregates, water and mixtures. It is a material that can be cast into different shapes such as hollow block, pipes or drainage and many more. It is durable and the most attractive construction material in terms of compressive strength. Also, its increasing use is fundamental for sustainable construction.
Sustainable concrete materials and sustainable steel reinforcement have been introduced to civil engineers to get closer to the sustainable development. Sustainable buildings constructed with use of these materials have shown an increased service life and the final cost has been reduced due to them.
When trying to design for automated construction systems, all parameters of a construction process must be integrated accurately and constantly to satisfy relevant parties, and finally, the quality of construction materials and products in terms of geometry, physical and design aspects will be changed. In order to reach automated construction goals, all the following aspects have to be fulfilled:
