PROPERTIES AND REQUIREMENTS OF GOOD R.C.C. Corrosion of steel is the predominant deterioration mechanism of reinforced concrete structures throughout the world. A short summary of this paper. These units have the advantage of acquiring speedy construction as only assemblage is necessary. The concrete that is used for pumping must be of adequate workability so that it is easily conveyed through the pipe. Fiber-reinforced concrete (FRC) is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. Here heavy weight aggregates are used. Thus in prestressed concrete entire concrete is utilized to resist the load. [3] There should be proper cover to the reinforcement, so that the corrosion is prevented. Chapter 2 contains limits on the specified compressive strength of concrete and the types of non prestressed reinforcement that are permitted to be specified for reinforced concrete diaphragms. The areas where there is thick reinforcement, self – consolidating concrete works best. The ready-mix concrete is very precise and specialty concrete can be developed based on the specification with utmost quality. The pervious concrete is created by unique mixing process, performance, application methods etc. However, most commonly used fibers are steel and glass fibers.

Fiber-Reinforced Concrete (FRC) Concrete is relatively brittle, and its tensile strength is typically only about one tenths of its compressive strength. The slump value will be between 650 and 750. 9.3 Bridge Types Reinforced concrete sections, used in the bridge superstructures, usually consist of slabs, T-beams (deck girders), and box girders (Figure 9.3). These are concrete types into which air is intentionally entrained for an amount of 3 to 6% of the concrete. The slab may be supported by walls or by reinforced concrete beams usually cast monolithically with the slab or by structural steel beams or by columns, or by the ground. All. This increased strength is achieved by decreasing the water-cement ratio even lower than 0.35. It also determines other properties, such as workability of fresh concrete. It is an important construction material used extensively in buildings, bridges, roads and dams. When such structural element is used stresses developed due to loading has to first nullify these compressive stresses before introducing tensile stress in concrete. In 1963 Romualdi and Batson published their classic paper on FRC. The specifications for the RC-series of designated concretes include requirements for maximum w/c ratio (W/C) and minimum cementitious content (MCC), which makes specification easier and complete. The reinforced cement concrete is defined as the concrete to which reinforcement is introduced to bear the tensile strength. PDF. These concretes conform to a particular standard but in no case, will be limited to strength. 3. Different Types of concrete slabs in construction:-There are 16 different types of Slabs in Construction. [5] It is a good fire resistant material. About this page. Different coloring stains and texture work will finally give a finish that is very similar to costlier natural stones. Author.

Type II: Moderate heat of hydration and sulfate resistance Type III: High early strength (rapid hardening) Type IV: Low heat of hydration Type V: Sulfate resistant The proper proportions, by volume, of the mix constituents determine strength, which is related to the water to cement ratio (w/c). Introduction. The material used in PSC is high tensile steel and high strength steel. In 1963 Romualdi and Batson published their classic paper on FRC. is typically reinforced with steel bars, in which case it is known as reinforced concrete. Prestressing the concrete is one of the method of utilizing entire concrete. Hence to achieve economy the concrete in tensile zone may be replaced by bricks or tiles. These products are renewable and easily cleaned. Types of Columns Columns are divided into three types according to the way they are reinforced. Pervious or permeable concrete are concrete that are designed such a way that it allows the water to pass through it. The principle of prestressed concrete is to introduce calculated compressive stresses in the zones wherever tensile stresses are expected in the concrete structural elements. Un-Reinforced Concrete Pavement (URCP) The rigid pavement in which reinforcement is not provided is called unreinforced concrete pavement. The more the finer material used, greater will be control achieved on the mix. Concrete is the most commonly used man-made material on earth. Hence the placement of reinforcement will take up the responsibility of bearing the tensile stresses. QTypes of Reinforced Concrete Columns 1. Thus in R.C.C. Members reinforced with longitudinal bars and continuous spirals. RC is used for a series of designated concretes that are used in concrete that will be reinforced, pre-stressed or containing embedded steel. The pipe used will be rigid or a flexible hose that will discharge the concrete to the desired area.
