What is reinforced cement concrete?

The article aims to answer the question, “What is reinforced cement concrete?”. It will also explain what fiber-reinforced concrete is. 

What is reinforced cement concrete?

RCC, or reinforced cement concrete, is a composite construction material that combines structural concrete with a reinforcing element, often steel. Steel is the most popular reinforcing material because of its complementary qualities, and the resulting material is known as steel reinforced cement concrete or simply Reinforced Cement Concrete.

Reinforcing bars or reinforcement are the steel bars used to strengthen concrete. What makes steel appropriate for reinforced concrete is discussed in this article. Mild steel and high yield strength steel are the two most common types of steel used to make reinforcing bars. 

Reinforcing concrete (RCC) also uses steel fabric, formed when cold-drawn steel wires are welded together. Concrete reinforced with fiber is also widely used in construction. Every person on the planet consumes an estimated one ton of structural concrete annually. 

Water is the only resource used by humans in such vast quantities. Concrete is used in every infrastructure project since it is the best construction material. Using the right formwork, it may be shaped into various forms.

Why reinforced cement concrete is better than concrete?

Continue reading the article to understand why reinforced concrete is better than concrete:

While it can withstand pressure, plain concrete doesn’t flex very well. Its tensile strength is just about a tenth of its compressive strength, which is already relatively low. Cracks and breaks appear in a simple concrete part when it is bent. 

It is for this exact reason that plain concrete is avoided in areas where bending motion could occur. A material’s tensile strength is measured by its resistance to bending stress. Beams and columns, flexural members, experience tensile stresses due to bending forces. 

The total bending capacity of plain concrete is increased when steel, which is more vital than concrete by a factor of more than a hundred, is added as a reinforcement. Steel reinforcement bars work as a monolith with the concrete, compensating for the material’s inherent weakness in tension. 

The resulting structure is very sturdy when concrete and steel bars work together to resist stress. As human bones do for the flesh and bulk surrounding them. Think of a beam that is simply supported on both ends and bears a weight equally distributed throughout its length. 

Under stress, bending is the primary form of deflection. This causes tension at the base of the beam and compression at its peak. Because concrete is brittle under tension, reinforcement bars will be installed at the beam’s base to prevent cracking.

Concrete is a go-to construction material because of its low cost, vast availability, and excellent compressive strength. Concrete has been in use for more than a thousand years. After the invention of Portland cement in the early nineteenth century, cement concrete quickly gained popularity.

Despite its impressive compressive strength, concrete’s tensile strength is only around 10% of its compressive strength and 0 when fractures have developed. Beginning in the late 19th century, the tensile strength of concrete was improved by adding reinforcing elements like iron or steel rods. 

Steel bars, known as reinforcement bars (rebars for short), are often used nowadays to strengthen the stress zone of concrete. Reinforced concrete includes such materials. Ribbed reinforcing bars increase the concrete’s resistance to bond stresses because concrete and steel flex together in reinforced concrete.

Using the proper formwork, reinforced concrete may be molded into any intricate design. It is cheap, long-lasting, and resistant to fire and wears. It’s a composite material made of concrete and steel, with the steel reinforcing providing the tensile strength that concrete lacks. 

The reinforcement has to have high strength, high tensile strain, an excellent connection to concrete, and thermal compatibility to create a robust, ductile, and long-lasting building. Steel reinforcement is utilized in columns and elsewhere because of its ability to withstand compression stresses. 

Reinforced concrete makes the slab walls, beams, columns, foundation, and frames. Both in-situ and off-site prefabrication methods may be used to create reinforced concrete.

What is fiber reinforced concrete?

Fiber-reinforced concrete has gained much attention in recent years, and there is a lot of active research on the material. Steel, plastic, glass, and other materials produce fibers. Many investigations have shown that ordinary concretes may benefit significantly from including such fibers in practical amounts (often up to around 1% or 2% by volume).

Fiber reinforced concretes’ compressive strengths are not noticeably higher than those of concrete made with identical mixes but without fiber reinforcement. Conversely, the resultant concrete is far more durable and resistant to cracking and damage.

Fibers have decreased the brittleness of concrete, allowing for more flexibility in its application. Remember that a reinforcement bar only adds strength in the bar’s direction, whereas fibers arranged at random do so in every direction.

The majority of fibers are made of steel. As long as the resultant concretes have a cement mortar covering the fibers, they seem reasonably robust. Steel-reinforced concretes find widespread use in paving, thin shells, precast goods, and repairs and overlays. 

Spray-on treatments, like shotcrete, are a common place to find glass fibers.

What are the uses of reinforced concrete?

Concrete is a flexible building material made by combining cement, sand, gravel, and water in the right proportions, then allowing the mixture to solidify. While its compressive strength is muscular, concrete’s tensile strength is modest, as is common knowledge. 

Using plain concrete in places where tensile stresses would be present, such as in slabs and beams, is not advised. Since steel has both great tensile and excellent compressive strength, so it may be used as a reinforcement in concrete. 

Reinforcement is what you get when you mix concrete with steel, and it works well. Because of the partnership, the material is now often referred to as Reinforced Cement Concrete. Reinforced concrete constructions are solid and long-lasting. 

It has impressive compressive and tensile strengths. It’s cheap, and the upkeep is little. Most corrosion and bending may be avoided using R.C.C. It can withstand heat, flames, and many weather conditions.

Aesthetically, R.C.C. buildings are sufficient. Therefore, they need not be clad. The resource is accessible everywhere around the globe, and its manipulation does not need specialized knowledge or equipment; standard skilled labor is sufficient.

Conclusion

Adding reinforcement to regular concrete significantly boosts its compressive and tensile strengths, earning the material the name “reinforced cement concrete” (R.C.C). Concrete is a flexible contemporary building material that combines cement (or lime), sand, crushed rock or gravel, and water in the proper proportions.

Highways, roads, traffic tunnels, hydro-power tunnels, irrigation canals, sewers, and every other imaginable structure have all used it.
