Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). Concrete on its own has one major downfall and that is that it is extremely strong in compression but has little to no strength when there is tension. Concrete is durable —its lifespan is actually two or three times longer than other common building materials. Steel framing is an increasingly popular construction option due to its modern aesthetic qualities and environmental advantages. Unlike steel, it is also possible for large sections to be pre-fabricated off site. When it comes to the cost of production and the cost of assembly, nothing can beat a pre-engineered steel building. Manhole rehabilitation is an increasingly sought after service, which needs highly trained staff like ourselves to work in confined spaces. Concrete has comparable coefficient of thermal expansion to steel. This means that every time you visit this website you will need to enable or disable cookies again. In the UK rebar is 100% recycled scrap steel and at the end of its life steel can be recovered, recycled and used again. To keep protecting the environment, reinforcing steel is now commonly used. Steel requires expert welders and careful torquing of screws. Let us summarize their major characteristics that would highlight each material.Steel is very strong in both tension and compression and therefore has high compressive and tensile strengths. Concrete imparts protection to steel in corrosive environments due to existence of CH and other alkalis. Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials. The ability to deliver projects to the highest standard with 20 years of experience makes OnSite SM a comprehensive and reliable service. It can withstand a considerable amount of external pressure. Saves Construction Time: Precast Concrete construction saves time, the risk of project delay is also less. Concrete can withstand high temperatures better than wood and steel. Advantages of Reinforced Concrete So for safety and cost effectiveness over the long term, concrete reigns supreme despite the need for on-going maintenance and repair. Metal corrosion is a well known problem. Steel: While concrete’s 2-day cycle may seem to give it an unarguable advantage, steel provides many construction benefits of its own. Efficiency: The rise of 3D modeling technology guarantees steel frames will be built precisely to a building’s specifications, which reduces the risk of error. Steel can be made from iron, carbon, manganese, phosphorous, sulfur, silicon, nickel, chromium etc., Steel is also used in making household appliances. Steel offers aesthetics that concrete may never be able to. If the foundation beneath the slab is not sound, the new concrete could sink or develop deep potholes. With two materials offering such diverse positives then it would be wrong to apply them together, right? “steel 1.2 × 10−5 and concrete 1.0–1.5 × 10−5”. Pouring concrete over old concrete instead of directly over a new gravel foundation limits your ability to maximize the slab's lifespan. Find these key facts If you don’t know what grain storage solution is right: Disadvantages of Concrete are as follows: Concrete has a very low tensile strength and requires the use of reinforcing bars in concrete tensile zone. Affordability; One of the main reasons that individuals are looking to construct a steel building over a concrete one is because of the difference in cost that the two offer. Both concrete and steel framed structures have environmental issues associated with their use, including a high embodied energy in their manufacture. Rebar is used within concrete to give it the ability to carry tensile loads on a structure. Concrete can withstand heat for 2–6 hours enabling sufficient time for rescue operations in case of fire. Advantages of Masonry Structures Masonry is extremely solid and can last a long time. The strength to weight ratio of steel is higher than any other (affordable) construction material. Concrete is basically just "put up the formwork, place the reinforcement and pour the concrete."

Hence, steel structures are earthquake resistant whereas concrete structures are brittle. However, with the addition of passive fire protection, such as spray-on fireproofing, buildings built of structural steel can sustain greater temperatures and, therefore, provide additional safety. Concrete “Concrete has been used for structures since Ancient Greece and Rome,” said Marianne Fourie of the International Federation for Structural Concrete. At the same time, it can also reduce the transportation cost of components formed by off-site migration. Structural Steel:Structural steel is extremely strong, stiff, tough, and ductile; making it one of the leading materials used in commercial and industrial building construction.

Steel structures are assembled by bolting or welding the pieces together on site as soon as they are delivered as opposed to concrete, which takes weeks to cure before construction can continue. Compared to steel, concrete can endure very high temperatures for long periods and offers excellent protection from explosions. Industry experts prefer the use of structural steel over any other building material for construction. The precast concrete casting can be carried on simultaneously with other works on site such as earthwork, survey, etc. Advantages of concrete. Calcium silicate hydrate, C-S-H, which is the main binder in concrete can withstand until 910 deg C. Concrete is a bad conductor of heat it can store considerable amount of heat from the environment. Along with many advantages, reinforced concrete also poses some disadvantages also. Building with concrete is also very fast. Advantages of Reinforced Concrete   Reinforced concrete has a high compressive strength compared to other building materials. Based in Nottingham, a fully trained and committed team are able to work across the whole of the UK for a wide range of clients. Steel structure construction has numerous advantages over concrete construction. When time means money this makes it a particularly attractive option. The steel structure is light in weight, and the building materials used in the walls and roof are much lighter than those in brick-concrete walls and terracotta roofs, which can effectively reduce the overall weight of the steel structure warehouse without compromising its structural stability. (Burj Khalifa, Dubai – 330,000 cubic meters of concrete used). Steel is a kind of metal and Steel is resistant to rust. Thus concrete can be used irrespective of ambient weather conditions and optimized with admixtures if required. Concrete vs. steel - Designing Buildings Wiki - Share your construction industry knowledge. 2. Using these wastes improves the properties of concrete as well thus quality of the structure is not compromised. This website uses cookies so that we can provide you with the best user experience possible. Concrete:Concrete is a composite material consisting of cement, sand, gravel and water. Reinforced concrete with steel is by far, a lot better than either concrete or steel separately. Due to this property, it is ideal to underwater and submerged applications like for building structures, pipelines, dams, canals, linings and waterfront structures Pure water is not deleterious to concrete and not even to reinforced concrete, chemicals dissolved in water such as sulfates, chlorides and carbon dioxide causes corrosion. Compared to steel, concrete can endure very high temperatures for long periods and offers excellent protection from explosions. Concrete can be hence poured into various formworks or shuttering configurations to form desired shapes and sizes at construction site. It includes an expanding agent in it to increases the volume of the mixture while giving additional qualities. “We believe structural steel framing systems are the way of the future,” says Cross. But as everything else in the world, there are certain downsides of using structural steel in building structures. Companies also offer concrete repairs which tend to be a lot quicker, simpler and cheaper than other repairs on steel structures. Concrete Hardens at Ambient Temperature, 5. Following are a list of advantages of steel structure construction offers: 1. It has a relatively high compressive strength, but lacks tensile strength. Concrete buildings offer many safety advantages over steel skeleton structures. This combination is made to use the compressive strength of concrete and tensile strength of steel at the same time, hence, work together to resist many types of loading. Most buildings that are made, are structurally made from steel. Some other benefits of steel that make it a popular choice in commercial buildings include: 1. Steel structures can withstand outside weights, for example, earthquakes, thunderstorms, and cyclones. Fresh concrete is flowable and is in liquid state. Moreover, concrete contributes to compressive strength of reinforced concrete members and structures. It is lighter than conventional concrete (Dry Density 300 kg/m3 up to 1840 kg/m3). This is because cement is a low-temperature bonded inorganic material. Concrete sets, hardens, gain its strength at regular room temperature or ambient temperature. Concrete is a conventionally used material for construction while steel is now gaining momentum for its flexibility and reduced construction time. Application in Reinforced Concrete. Thus concrete production can significantly reduce environmental impacts due to industrial waste. Production of structural steel demands 8000 kWh/ton or more to make which is almost 3-10 times the energy consumption. Concrete imparts protection to steel in corrosive environments due to existence of CH and other alkalis. 2. Concrete has comparable coefficient of thermal expansion to steel. They are discussed below. Its reflective properties will decrease air-conditioning costs in the hot summer months. One of the major advantage of concrete is its ability to be used in different application methodologies. Steel, glass and wood can transfer noise from the outside world into the interior of a building. The term reinforced is used because the steel reinforces the concrete and makes it […] Reinforces the volume of the concrete. This is of course why it is the natural choice of many of the buildings that we work on where safety is paramount. Advantages of Concrete – Low Maintenance 8. Although some concrete buildings may not look great, who’s to say that in the future decorative coatings and innovative designs cannot lead the way in construction?

Comparison Steel Vs Concrete Steel Concrete Safety : Experts acknowledge that steel can soften and melt with exposure to extremely high temperatures. “Technological improvements and innovations over the centuries have refined its use. For plain cement concrete only 450–750 kWh/ton energy is required and that of reinforced concrete is 800–3200 kWh/ton. In Brazil the lack of steel-skilled workers is such that a welder easily earns more than an engineer. Continue to browse if you're happy with our Privacy & Cookie Policy. Steel has an ultimate strength of about 400 to 500 MPa (58 – 72.5 ksi). Reinforcing concrete with steel has major benefits. Concrete is hand applied, poured, pumped, sprayed, grouted and also used for advanced applications like shotcreting in tunnels. Concrete has a higher soundproofing capability than other building materials. A steel/RCC structure does not have to be treated with chemicals as it is a prerequisite for the wood. “We believe that they result in an accelerated schedule. The ability to deliver projects to the highest standard with 20 years of experience makes OnSite SM a comprehensive and reliable service. Steel stands out for its speed and efficiency in construction.
