This construction material is made of steel and it is assembled with nuts and bolts. Compared to steel, concrete can endure very high temperatures for long periods and offers excellent protection from explosions. Using these wastes improves the properties of concrete as well thus quality of the structure is not compromised. If the foundation beneath the slab is not sound, the new concrete could sink or develop deep potholes. 2. Fresh concrete is flowable and is in liquid state. “We believe that they result in an accelerated schedule. ; Expensive formwork is required for casting and molding and to hold the concrete in place until it hardens sufficiently. This is because cement is a low-temperature bonded inorganic material. Steel offers aesthetics that concrete may never be able to. Compared to engineered cementitious materials used for construction, the production cost of cement concrete is very low. Reinforced concrete, as an economic building material, is very popular nowadays. Concrete can withstand heat for 2–6 hours enabling sufficient time for rescue operations in case of fire. Possibility of steel corrosion and subsequent concrete deterioration is declined because concrete is crack-free. Reinforced concrete with steel is by far, a lot better than either concrete or steel separately. 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 a conventionally used material for construction while steel is now gaining momentum for its flexibility and reduced construction time. Steel structures can withstand outside weights, for example, earthquakes, thunderstorms, and cyclones. Lastly, a steel structure is well grounded and less probable to be hit or impaired by lightning. “steel 1.2 × 10−5 and concrete 1.0–1.5 × 10−5”. Production of structural steel demands 8000 kWh/ton or more to make which is almost 3-10 times the energy consumption. Though chemical in water can induce corrosion in concrete and reinforced concrete. 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. 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. Disadvantages of Concrete are as follows: Concrete has a very low tensile strength and requires the use of reinforcing bars in concrete tensile zone. Advantages of Reinforced Concrete Advantages of Concrete – Low Maintenance 8. The Advantages of a Timbertank. We also believe that quality is enhanced because of off-site fabrication, and that the productivity opportunities that exist in … Advantages of steel fibre concrete. Improved flexural strength. All of these are readily available in local markets at low cost. Major ingredients of concrete are cement, water and aggregates. Rebar is used within concrete to give it the ability to carry tensile loads on a structure. 10 major advantages of concrete are explained below. 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 is not as resistant as steel. Steel is a highly durable metal. Steel structure construction has numerous advantages over concrete construction. ADVANTAGES OF CONCRETE OVER STEEL STRUCTURES Due to the high cost of lumber in urban areas and the massive size of needed structural elements, it is usually steel that competes with concrete. This includes both corrosion of internal walls due to the stored bulk solid and also external corrosion caused by moisture. The scrap value of concrete is nil : The scrap value of steel is good : Self-weight: The self-weight of concrete is more : The steel is 60% lighter than the concrete: Foundation: The foundation for the concrete structure should be strong because of the larger weight of concrete: The steel structure can be made without foundation: Construction time This means that every time you visit this website you will need to enable or disable cookies again. Hence, steel structures are earthquake resistant whereas concrete structures are brittle. Steel requires expert welders and careful torquing of screws. Weld-checkers swim in cash. The implementation of these fibres also improves the resistance to flexotraction. Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). It is lighter than conventional concrete (Dry Density 300 kg/m3 up to 1840 kg/m3). Thus concrete can be used irrespective of ambient weather conditions and optimized with admixtures if required. Steel on the other hand, in terms of cost, is generally a cheaper option. Unlike steel, it is also possible for large sections to be pre-fabricated off site. There are many advantages that the material offers including a lower requirement for maintenance, lower impact on the environment, and high levels of durability. Concrete can be hence poured into various formworks or shuttering configurations to form desired shapes and sizes at construction site. Manhole covers have been seen powerfully flying up into the air across the world. The first advantage is that the volume of the concrete is reinforced due to the homogeneous distribution of the steel fibres. Reinforces the volume of the concrete.
