Reinforced concrete can be classified in many ways. 2. B. Fire-resisting and durability Therefore, the scrap value of concrete is almost nil. … Fire and weather resistance of reinforced concrete is fair. To improve the long term durability an Alkali resistance glass fiber reinforced concrete is also invented. It increases the durability of the concrete. If concreting is not done properly the steel starts corroding thereby loosing strength and ultimately the life gets reduced. It increases the properties like toughness, tensile strength, ductility. Reinforced concrete, concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. What is reinforced concrete | Advantages & Disadvantages. While balconies can provide many benefits, they can lead to long-term repair issues if not properly maintained. 10 major advantages of concrete are explained below. Question 3. Due to the provided reinforcement, reinforced concrete can also withstand a good amount of tensile stress. The CBA has created an online portal, backed up with an events programme focused on the benefits of using concrete blocks. Distribution of shear intensity over a rectangular section of a beam, follows: A. What are the advantages of reinforced concrete beams compared with plain concrete beams? The Concrete which includes fibrous substance to increase structural strength and cohesion, it is called as a Fiber Reinforced Concrete. D. All the above. Prefabricated concrete structures ↑ They are produced at the construction site of the pre-prepared items. Fibers keep the crack small which leads to longer life of the structure. Reinforced concrete has a high compressive strength compared to other building materials. (i) Structures made from Reinforced Concrete are durable. The bond is assumed to be perfect in the design of reinforced concrete the bond between steel and concrete can be increased by the following methods: Using deformed or twisted bar. Therefore, no internal stresses are set up within reinforced concrete due to the temperature change. Fibers give post cracking strength. A circular curve. In the reinforced concrete, the ultrasonic wave transmitted in the concrete and steel-rebar includes both body wave and guided wave, which is easily affected by corrosion of the reinforcement concrete due to variations of acoustic transmission route caused by changes of the physical properties of the acoustic media. 3) Fire and weather resistance of reinforced concrete is fair. This is very necessary for the material to be able to withstand the loads on the pavement. REINFORCED CONCRETE PAVEMENTS 13-1. Following are the benefits one can obtain of a fiber reinforced concrete: It increases the tensile strength of the concrete. It plays an important role in the earthquake resistance as … Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. It increases the properties like toughness, tensile strength, ductility. K. McKay‘ (Author of Building Construction), the difference in cost, performance and maintenance between steel and reinforced concrete framed (multi-storey) structure is negligible, and none of these options has any marked advantage over the other. Change ), You are commenting using your Facebook account. Advantages Compressive strength. When rebar corrodes, the oxidation products expand and tends to flake, cracking the concrete and unbonding the rebar from the concrete. ( Log Out /  “Concrete cover, in reinforced concrete, is the least … Your email address will not be published. (ii) It has a high compressive strength (due to concrete). 2. Advantages of Reinforced Concrete. D. All the above. It brings a greater economy and finished the construction. That reinforcement gives concrete strength against its weakness I.e. Unlike natural stones, concrete is free from defects and flaws. 1. A. Monolithic character Cost effective construction material when it comes to certain structures like dams, footings, and piers. Can take any shape with the right moulding. The portal includes guidance aimed across the construction industry, with everything from datasheets to support design, supplier choice advice and guidance as to the benefits of concrete blocks. The reinforced concrete building system is more durable than any other building system. If one component fails, the load is transferred to other components and the structure stands. A field density test is a common test used to determine the field density of the soil or pavement. Concrete has a good ability to protect reinforcing steel bars from fire for extended periods. (iii) It has a high tensile strength (due to reinforcement). There are 100s of advantages of Reinforced Concrete, but here we will discuss some important advantages of Reinforced Concrete. Glassfibre Reinforce Concrete (GRC) is a composite material comprising a mixture of hydraulic cement, silica sand, alkali resistant glass fibres and water. Mcq Added by: Muhammad Bilal Khattak. Fire and weather resistance of reinforced concrete is fair. The reinforced concrete building system is more durable than any other building system. Perhaps the greatest advantage of reinforced concrete construction is continuity. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. How is the modulus of elasticity of concrete determined? B. Fire-resisting and durability. Post was not sent - check your email addresses! Additionally, what are the advantages and disadvantages of steel as a structural material? Concrete is one of the best construction materials widely known for its sturdiness and durability. Also the repairs are then very expensive and difficult. The maintenance cost of reinforced concrete is very low. Structural engineering depends on the knowledge of materials and their corresponding properties for us to better predict the behavior of different materials when applied to the structure. How do I calculate volume of 50 Kg cement bag? It can be cast to any desired shape. advantages and disadvantages of Reinforced concrete. tensile strength, but there are some drawbacks also of that reinforcement. Advantages of reinforced concrete 1. Following are the benefits one can obtain of a fiber reinforced concrete: It increases the tensile strength of the concrete. Many researchers prove that the addition of small, closely spaced, and uniformly dispersed fibers to concrete plays the role of cracker arrester and substantially enhance its static and dynamic properties. 2) Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress. During our inspections, we often observe cracks and spalls in the concrete perimeters of the balconies.
