    3.Concrete corrosion and the stages: 3.1 Reinforcement corrosion Reinforcement corrosion refers to the electro-chemical or chemical reaction between the reinforcement bar and the environment, causing its deterioration. The causes of corrosion in concrete can be explained practically or in terms of electrochemistry. Some of the factors affecting corrosion include the presence of aggressive species, for instance chlorides and their quantity. This species breaks down the reinforcing bar protective

    Concrete - a composite material consisting of a proportionate mix of water, cement, sand and stone (aggregate) is the most widely used building material in the construction industry globally. It is the inherent mechanical properties of concrete which makes it such favourable building material. When concrete is freshly made, it can be placed, compacted and finished with relative ease without the segregation of the individual materials. When concrete sets and hardens, it becomes a durable stone-like

    Concrete is an artificial stone-like material used for various structural purpos-es. The word concrete originates from the Latin word concretus which literally means compact or condensed. Concrete has been used for many amazing things throughout history, including architecture, infrastructure and more. The Egyptians were using early forms of concrete over 5000 years ago to build pyramids. They mixed mud and straw to form bricks and used gypsum and lime to make mortars. Joseph Aspdin of England is

  • The Pros And Cons Of Concrete

    1433 Words  | 6 Pages

    Concrete is the primary material in construction industry. It consists of cement, coarse aggregate, fine aggregate, water and other admixtures. Generally Ordinary Portland cement is used in concreting but the production of OPC causes a huge amount of carbon emission and also it uses a huge amount of non-renewable natural resources. The concrete construction practice in use is considered as unsustainable because it consumes a huge quantity of sand, stone and water and 2.5 billion tons of OPC per year

  • Disadvantages Of Concrete Design

    1318 Words  | 6 Pages

    Introduction Concrete is widely used in constructions and that is because it can be easily placed and handled and could be casted into various shapes and forms, like any other construction material concrete has its advantages and disadvantages, many studies have been done to reduce the disadvantages and minimize their effects on structures, some of the disadvantages are listed below. 1. Low tensile strength. 2. Low post cracking capacity. 3. Brittleness and low ductility. The presence of micro

  • Tension Stiffening In Concrete

    3795 Words  | 16 Pages

    This paper presents the results of an experimental study on the tension stiffening response of fusion bonded epoxy coated bars embedded in self compacting concrete (SCC). 18 numbers of direct tension specimens recommended by RILEM standards are used with modified specimen lengths of 40 and 50 times the diameter of the bar. From the study it is concluded that fusion bonded epoxy coating on bars has a negative effect on the tension stiffening of SCC. The reduction ranges from 9.4 % to 32% .The tension

    Reinforced Concrete – A New Way To Build What Is Reinforced Concrete? A substance similar to stone that is obtained as a result of combining cement, sand and other aggregate along with water. Once they are combined, they are left to turn hard and this can take up any shape or structure depending on the structure of the building. One of the latest technologies in civil engineering design services is the use of reinforced concrete. Even though the concrete material is strong in terms of compression
