What is a Concrete Beam? (with pictures) - Info Bloom

Sonal Panse Concrete beams are widely used in contemporary building construction. In structural engineering, a concrete beam is a load-bearing unit that can be used to carry both horizontal and vertical loads.Known as reinforced concrete beams or reinforced cement concrete (RCC) beams, these beams are made by encasing steel bars, plates, or fibers within the concrete.

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

Generally, when the stone ratio is more than the sand, this concrete cures a little stronger than a 1:3:3 ratio. The difference is in the workability of the concrete.

How Concrete is Made - Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
