What is the difference between reinforced concrete and pre stressed concrete?
Reinforced concrete has reinforcing bars (called rebar) simply embedded in the pour. With prestressed concrete, reinforcing rods or cables are stretched (stressed) and then the concrete is poured around them. After the concrete hardens, the tension on the reinforcing members compresses the concrete, making it more resistant to failure where poor soil conditions or severe loads exist.Prestressed construction is usually done in-plant because of the equipment involved, and the completed assembly shipped to the site for installation.A similar method, called post-tension, is usually done on site, and involves the tensioning of reinforcing cables after the slab is poured, using a special hydraulic jack.

What are the differences between the mass concrete and reinforced concrete?
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.
What is the difference between structural steel and reinforcement steel?
structual steel is the widw flange column's and beam's as well as plate steel angle iron ect.. it falls under aws D1.1 welding code. reinforcement steel/reinforcing steel is the rebar, dba,(deformed bar anchor), hsa, (headed stud anchor) that is placed in concrete, floors, walls, footings, ect... it falls under aws D1.4 welding code
How do you strengthen concrete with reinforcing rod?
Rebar is used to strengthen concrete because of its strength and flexibility. In order for these rods to work, there must be ample space between the rebar and the edge of the concrete piece.

What is the difference between lean concrete and mass concrete?
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.

What is the difference between the singly reinforced beam and doubly reinforced beam?
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
Doubly reinforced concrete vs singly reinforced?
Doubly reinforced concrete and singly reinforced concrete are two types of reinforced concrete structures that differ in the way reinforcement is provided to resist tensile forces. Singly Reinforced Concrete: Singly reinforced concrete refers to a structural element (such as a beam or a slab) where reinforcement is provided only on one side to resist tensile forces. Typically, steel reinforcement in the form of bars or meshes is embedded in the concrete in the tension zone, where the concrete is subjected to tensile stresses. The reinforcement helps to carry the tensile forces, while the concrete primarily resists compressive forces. Singly reinforced concrete is commonly used in many structural applications. Doubly Reinforced Concrete: Doubly reinforced concrete refers to a structural element where reinforcement is provided on both sides to resist tensile forces in different zones. In addition to the primary reinforcement on the tension side, secondary reinforcement is also provided on the compression side to increase the structural strength and control the development of cracks. The secondary reinforcement helps balance the tensile and compressive forces, improving the overall performance and load-carrying capacity of the element. Doubly reinforced concrete is often used in situations where higher strength and resistance to cracking are required, such as in deep beams or heavily loaded structural members. The decision to use singly or doubly reinforced concrete depends on factors such as the structural requirements, loads, span lengths, and design considerations. Doubly reinforced concrete is typically employed in situations where the loads are higher or where there is a need to control deflection or cracking to a greater extent. It provides enhanced strength and ductility to the structural element. However, it also requires careful design and detailing to ensure proper placement and spacing of the reinforcement on both sides. It's important to note that the design and implementation of reinforced concrete structures should always be carried out by qualified structural engineers who consider the specific project requirements, local building codes, and safety factors.
