properties of reinforced concrete pdf

Reinforced concrete, concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. Thus the concrete and the material reinforced shall have the same strain. Steel is poor in durability and fire resistance while concrete is good, therefore concrete must provide cover to, The tensile strength of concrete is only about 10 per cent of the compressive strength. 0000002002 00000 n ... Reinforced concrete has been used in a variety of applications, ... added to the concrete mix to improve the properties of concrete Course Hero is not sponsored or endorsed by any college or university.

In the FRC, a numbers of small fibres are dispersed and distributed randomly in the concrete at the time of mixing, and thus improve concrete properties in all directions. ADMIXTURES Admixtures are mixed into the concrete to change or alter its properties, ie the time concrete takes to set and harden, or its workability. reinforced concrete structures are designed on the assumption that the concrete does not resist any tensile forces. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). endstream endobj 134 0 obj <>stream View Lect.2-Properties of Reinforced Concrete.pdf from AGEN 111 at Egerton University.

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. Reinforced concrete is a composite material, and the average density is considered to be 150 lb/ft3. PROPERTIES OF REINFORCED CONCRETE 2.0 Introduction Reinforced concrete consists of both concrete and steel. Reinforced concrete is a strong durable building material that can be formed into many varied shapes and sizes ranging from a simple rectangular column, to a slender curved dome or shell. Construction Because fresh concrete is a viscous suspension, it is cast or placed and not poured. Composite action is achieved when there is perfect bond such that the strain in steel equals to that in the, coefficients of thermal expansion for steel and for concrete are nearly the same; therefore differential. combining the best features of concrete and steel. On the other hand, steel, is very good in tension, compression and shear.
