Summary
Producing Sustainable Self Compacting Concrete 14th December 2013 Abstract/Introduction Since the start of 1990’s, the concept of self-compacting concrete has attained much acceptance from different parts of the world. In the production of concrete, self-compacting concrete is a very important step since it ensures that this fabrication is sustainable through the reduction of the use of vibrators that are harmful to workers…

The methodology also entails shading some light on questions that relate to the topic and on the results of the 9 mixes of cement, fine aggregate, coarse aggregate, water, and fly ash. The work to be undertaken in this research involves doing a mixture of substances and finding out the results. Some of the risk assessment to consider in this research is such as; taking careful measures when mixing different substances, following given instructions carefully to avoid mistakes that can lead to inappropriate results and so on.

This new standard is proving according to research and many experiments to be one of a better future. In the Following paper, we shall discuss the production of self-compacting concrete cement, acrylic polymer, and fine aggregate sand. These are all part in the engineering sector of structures that are all around us. However, they are different in that they are the new technologies that most first world countries want to start using if they have not started already. The above new technologies are set to take the world by storm by their nature to create structures with a significant less affinity to deformity. The aforementioned precast concrete is a type of Self-compacting concrete. Production of a Sustainable Self-Consolidating/ Compacting Concrete According to numerous dictionaries, sustainability is the ability of maintaining a subject or an object. Dictionaries go further and state that the maintenance of an object has the ability to use the natural resource repeatedly without having to destroy the balance created naturally in the ecological system. In the construction world now, this definition states that manufactured concrete has the ability to utilize the natural resources without interfering with the ecological system. This brings forth an issue that the construction sector is experiencing. Is it possible to produce concrete that is friendly to the eco-system? The answer to this is yes it is possible (Park, 2010). Over a century ago, production of over ten metric tonnes of cement was produced in the construction sector. The whole world produces this amount. However, the amount of concrete produced was roughly around 40 million cubic meters. In the 1900 the total human population was roughly 1.64 billion people, the number now has more than quadrupled with the population staggering over 7billion people. In those times the amount of cement a person could use ...Download file to see next pagesRead More

How to achive sustainable concrete

...in which the glass was not used). Further according to Naik & Moriconi (2008), the use of mixed coloured glass can be applied in slurry or concrete that is self-compacting as well as flowable. The researchers further indicated that adding mixed coloured glass in concrete has the capability of increasing permeability of the concrete; thereby increasing the life of the concrete (Naik & Moriconi 2008). Therefore, mixed coloured glass can be used to partially replace sand while preparing concrete (Naik & Moriconi 2008). According Naik & Moriconi (2008), Glass Reinforced Plastic (GRP) processing in Western Europe which is...

...?Sustainable Concrete of the 22nd November, Introduction Manufacturing can be identified as the initial stage at which raw materials are converted into usable products. There exist numerous forms of manufacturing in the guest to produce the items commonly used around the world. The construction industry is what offers all mankind products in which to shelter. Concrete has been used in this industry for hundreds of years. In the manufacture of concrete, cement comes as the major ingredient although it is a processed product itself. This industry has been identified as causing massive environmental damages within the production area. The materials used like...

Properties of Self :Compacting Concrete using waste rubber tyres as partial replacement for coarse aggregate

...concrete is of an interesting nature. Self-compacting concrete flows into the designated region without segregation. The friction between particles in the self-compacting concrete is minimized. This is done by use of superplasticiser. Anyone can argue that addition of water would produce the same effect. However, water reduces viscosity and weakens the mixture. In addition, the self-compacting concrete loses its durability. Hence, it is not advisable to add water (Felekoglu, 2008, Pg.54). The size of the particles also influences the filling ability of...

Self Compacting Concrete

...Self-Compacting Concrete Self-Compacting Concrete Self-Consolidating Concrete (SCC) is a high- performing form of concretethat surges under its own weight to totally fill the formwork and self-consolidates without vibration. It was first introduced in Japan in the late 1980, but since then, the research and development of SCC have spread quickly around the world (Shen, et al., 2007, pg. 1). The development and introduction of Self-Compacting Concrete is widely considered as the biggest advance in concrete technology for...

Self Compacting Concrete

...Self-Compacting Concrete Schools Number and of November 28, Self-Compacting Concrete Self-compacting concrete (SCC), also known as self-consolidating concrete, is a specialized high performance concrete that does not need to be compacted by vibration as it compacts into every corner and space of a formwork as a result of its own weight. The most laudable property of SCC is that it leaves no void in the formwork, and that too, without the need of mechanical vibration (De Schutter, 2007; Okamura & Ouchi,...

.... For instance, in the United States, its production accounted for nearly 2 million jobs with some 2.7 billion metric tons produced in the same year, an equivalent of over 0.4 metric tons of the material produced per person each year. This shows that sustainable production of cement can ensure sustainable development of the society by sustaining employments, including of truck drivers, concrete equipment operators, carpenters, masons, iron workers, batch plant operators, surveyors, finishers, inspectors and architectures (Wilson, 2011). The cement industry must therefore continue to advance relative to the changeful needs and the...

FATIGUE BEHAVIOUR OF SELF COMPACTING CONCRETE SUBJECT TO CYCLE LOADING

...Fatigue Behaviour of Self Compacting Concrete XXXXXXXXX XXXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXXXX Fatigue is the internal damaged imposed on a material when it goes through a series of cycle loading. Through the process of cycle loading, there is the production of subsequent frequencies that play a major role in achieving the main aim of the task. The property of a certain material, not any one in particular but any other material is identified by the term fatigue limit. It is important to analyse this process in an effort to identify the manner through which crack of a material is achieved through the stated process of cycle loading. Different Alloys have specific limits through which any amplitude below the given one ensures... definitely has...

Benefits and technical challenges for using self compacting concrete

...; in such conditions vibration had been merely impossible. This challenge can now be resolved with self-compacting concrete (Persson, 2003: 374-379). The SCC flows easily around the reinforcement and into every corner of the formwork. The SCC is very fluid and passes around obstructions to fill all the corners and nooks without the risk of either mortar or any other ingredients of concrete detaching out, and simultaneously ensuring that there are no rock pockets or entrapped air. Self-compacting concrete produces a surface finish that is exceptionally good and patching is no longer necessary. SCC comes...

.... In fact, all buildings, roads, bridges that people use today are constructed with concrete. Some constructions like bridge over the Colorado River, built with strong concrete, are almost 250 yeas old. However, the changes in the manufacturing process, based on the research and developmental efforts have resulted in different types of concrete, being used presently. The use of admixtures and plasticizers to produce concrete of high strength is an example in this direction. History of concrete The background of concrete goes back to the time of Egyptian pyramids, which are almost 5000 years old. Since then, many...
