Importance of Permeability: In reinforced concrete, ingress of water and air will cause steel … The longevity of this popular material has made it important for the construction of permanent buildings and strong structures like bridges and dams. being recyclable and reusable, which increases its lifespan even further. Concrete is produced by mixing binding materials and inert materials with water. So, from this you can make out that how important is the use of concrete in construction equipments. A well-graded mixture in the concrete makes it much more robust than a poorly-graded concrete. Concrete is used to provide strength, durability, and versatility during the construction of a structure. The curing period of concrete is most important to keep going the hydration process of cement with water until concrete gets the maximum compressive strength. So there is no denying of the importance of concrete in the construction industry. It is an important construction material used extensively in buildings, bridges, roads and dams. This type of curing systems are generally adopted for railway sleepers, concrete blocks, pipes, manhole covers, poles, pipe culverts, prestressed precast concrete products, and so … Following are some interesting points that show you the importance of batching of concrete ingredients. Like with many other materials, concrete can change in quality as a result of its temperature. Why a good ready-mix concrete design is necessary. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Versatility. Well, first of all, concrete is really everywhere your eyes can see. For more information, feel free to get in touch with us. This is the reason why ready-mix concrete has become really popular in recent years to speed up the construction process and make it more reliable. Maintaining the proper temperature also plays a vital role in concrete as mentioned, it should not be colder than 5 0 C. … This can be especially important when there are certain temperature extremes where concrete is being poured. Reinforced Concrete and Importance of Rebar. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. Retrospectives without concrete action items are pretty much a complete waste of time (and this coming from a guy who thinks the Retrospective is the MOST important discussion in Scrum!!). Slab, the cover should be 15 mm. Using the right aggregates is important when it comes to the performance of the concrete – they make up between 60% and 80% of concrete, after all. These tests can be used to determine a broad range of concrete properties such as density, elastic modulus, strength, surface hardness and absorption, reinforcement location, size and distance from the surface. Concrete has applications in different types of construction materials. Basically, everywhere there is a structure, there is cement. Concrete cover for steel bar is much necessary to protect the steel against corrosion (rusting) and to provide resistance against fire. Compared to the other forms of construction, concrete constructions are more durable and resistant to conditions like weathering, erosion and natural disasters. These excellent properties have made concrete a reliable and long-lasting choice of construction companies for both commercial and domestic types of constructions. Some of the examples of Precast Concrete are; precast poles, fence posts, concrete lintels, … Previous Next. The presence of water is essential to cause the chemical action which accompanies the setting of concrete. But it is necessary to retain water until the concrete has fully hardened. While the importance of roads is well acknowledged, the economics of road building and maintenance could do with some more thought. Then, we can say that it is also very environmental friendly. It helped to prevent decay and corrosion to buildings, allowing them to survive longer. Concrete is an important building product. Pozzolana is one of the most standard features of concrete in central Italy. The concrete cover over the reinforcing steel is essential for ensuring the bond strength between concrete and steel. 1. In concrete, the single most significant influence on most or all of the properties is the amount of water used in the mix. The choice of type of roads to be built have conventionally been based on the economies of initial cost, with little emphasis paid to the overall life cycle cost of a road. Concrete Pavements are also energy-efficient in several ways. Awesome, right? HeidelbergCement Supplier Code of Conduct, The Importance of Concrete in Construction. The cement rarely ever gets fully hydrated and the full benefit of the total strength of cement will thereafter never be obtained. A water permeability test is one of the tests to determine the durability of … And why is so important? So concrete is the most important element of the most important industry. Its uses range from structural applications, to paviours, kerbs, pipes and drains. It is important to understand that compaction is a two-stage process and to recognise each stage because, with vibration, initial consolidation of the concrete (liquefaction) can often be achieved relatively quickly. Proper batching of concrete ingredients rectifies the confusion and errors. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause deterioration of concrete. Before any concrete is placed the entire placing, programme consisting of equipment, layout, proposed procedures and methods is planned and no concrete is placed until formwork is inspected and found suitable for placement. Concrete is Economical. The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water-cement ratio, curing methods and … This has worked in favour of … Every ingredient of concrete consists different properties so, it is not an easy task to get economical and good concrete mix. Definition and Significance of Durability: The durability of cement concrete can be defined as its ability to resist weathering action, chemical attack, abrasion or any other process of deterioration. Curing imparts better strength to the concrete. So, we all deserved a place where people passionate with this topic can find any kind of interesting, useful and fun information. The concrete produced out of the concrete batching plant is used in the foundations of building construction, paving materials for roads, plumbing and piping in construction projects etc. Thus the construction of modern concrete structures assumes much more importance for durability than in the past.
