New Concrete Materials Technology
Posted by adminJul 20
There are a number of significant progress in the field of new technology in the last ten years. There has been progress in almost all areas of concrete production, including materials and recycling, a mixture of proportionality, and the quality and sustainability of the environment. But it was not a lot of these innovations approved by the concrete industry, saw the concrete / buyers. There is always resistance to change, usually based on considerations of cost and lack of familiarity with new technology. Concrete latest technology is the beginning of acceptance in the industry to get. Can call some of the new concrete more interesting high-performance concrete (HPC), super high performance concrete and geopolymer. Have great merits and found some drawbacks compared to concrete in the level of use. The recycling of concrete high-performance, and thus reduce the material usually need to get rid of these materials. Some of these materials, including fly ash (secondary waste from burning coal), ground granulated blast-furnace dust and silica. But perhaps the biggest advantage of using some of these other substances to reduce the need to use cement, often referred to as Portland cement. Will decline in the production and use of cement have beneficial effects are numerous. These will include the benefits of a reduction in the formation of carbon dioxide emissions and reduce energy consumption, both going to be global warming. It is estimated that the production of cement in all parts of the world 5-8 percent of carbon dioxide emissions contribute. Furthermore, the use of fly ash and blast furnace is usually cheaper than cement and have characteristics that improve the quality of the final concrete. New technology with specific, concrete modern, and new forms of life in the measure, which extends over the centuries, not decades. The use of fly ash and other materials from by-product saves hundreds of thousands of hectares of land will be used for the disposal of waste. Fly ash and other products from the combustion of coal, and certain industrial wastes, the most common products on the planet. Will cancel the grave of waste products translate into less risk of contamination of surface water resources and groundwater. Compared with the level of concrete new concrete better resistance to corrosion, equal or higher pressure and tensile strength, resistance to the top of the fire, and rapid recovery and gaining strength. Moreover, the production and life cycle of this new concrete to reduce emissions of greenhouse gases by up to 90%. Bureau of Investigation is a new technique significantly much stronger tensile strength and passion (bending it) the strength of regular concrete. A fiber-reinforced concrete, which is combined with pre-mixed dry ingredients. It is much more compact than regular concrete and structures built with it will be a new concrete were much lower, probably less than 80%. High-density concrete Bureau of Investigation provides other features such as resistance to corrosion is very high from chemicals. FBI force eliminates the need for the development of steel in structural models. Bureau of Investigation, or a variant of fiber, metal, and will be used and / or superplasticizers for a number of structural elements at less than an inch thick. In general, building structures with the FBI will have a much greater age, and will be less maintenance than that. Channels is a new technology which is actually closer to the FBI. Channels used steel or organic fibers to create a concrete that is stronger than the FBI. Interestingly, the ancient Romans used horsehair concrete to improve its strength. Channels that are being tested for use in the quake-proof structures, bridges, tunnels, and nuclear containment structures. Although more expensive than conventional concrete, and there are a number of cost savings, which makes the price competitive. These cost savings are not iron is required, less material is needed in dealing with less labor costs, equipment and thinner and less weight and smaller structures with the necessary foundations. Moreover, both the FBI and canals, and low maintenance due to very low porosity, which is highly resistant to penetration by water or chemicals. Both are resistant to salt water corrosion, which is very harmful to the bridges and roads today.
