What are concrete poles used for?

What are concrete poles used for?

First designed and constructed by French engineer Freyssinet in the middle 1930s, prestressed concrete poles are used today worldwide for flag poles, sign poles, telephone poles, telegraph poles, and poles that support street lights, electric power lines, antenna masts, and overhead power lines for electric trains.

Which is the disadvantage of concrete?

The following are the disadvantages of concrete : Due to low tensile strength, concrete is required to be reinforced to avoid cracks. In long structures expansion joints are required to be provided if there is large temperature variance in the area.

What are the advantages and disadvantages of using concrete instead of using steel as a construction material?

Concrete: With proper construction and care, reinforced concrete is water resistant and will not corrode. However, it’s important to note that the steel reinforcement inside should never be exposed. If exposed, the steel becomes compromised and can easily corrode, compromising the strength of the structure.

Which is an advantage of cement concrete pavement?

Advantages Of Cement Concrete Roads: 1. Concrete roads have long life than any other roads. 2. These roads are durable and are practically unaffected by weathering agencies.

How much is a concrete pole?

Our concrete pole prices vary depending on the options chosen, such as color, series, and size. Generally, prices range between $700 to $1,000.

Which is disadvantage of concrete blocks?

Concrete Blocks are Expensive When compared to other traditional building supplies, concrete blocks add a considerable expense to a home construction. While the price of materials varies from region to region, concrete blocks typically cost two to three times as much as a more traditional wood construction.

What are the advantages of concrete over steel?

Concrete buildings offer many safety advantages over steel skeleton structures. Compared to steel, concrete can endure very high temperatures for long periods and offers excellent protection from explosions. Building with concrete is also very fast. When time means money this makes it a particularly attractive option.

What are the advantages and disadvantages of steel structures?

Advantages & Disadvantages of Steel Construction

• Reliability. Steel structures are very reliable.
• Industrial Behavior.
• Lesser Construction Time / Greater Erection Speed.
• High Maintenance Costs And More Corrosion.
• Fireproofing Costs.
• Susceptibility To Buckling.
• Higher Initial Cost / Less Availability.
• Aesthetics.

What are the advantages and disadvantages of concrete?

The durability of concrete is very high. It can be cast to any desired shape. The casting of concrete can be done in the working site which makes it economical. The maintenance cost of concrete is almost negligible. The deterioration of concrete is not appreciable with age.

Why is concrete so important in civil engineering?

The concrete plays a very important role in all branches of civil engineering. Ingredients of concrete are easily available in most of the places. Unlike natural stones, concrete is free from defects and flaws. Concrete can be manufactured to the desired strength with an economy. The durability of concrete is very high.

Which is better for a storm shelter concrete or cinder?

Concrete can withstand high temperatures. Concrete is resistant to wind and water. Therefore, it is very useful in storm shelters. As a soundproofing material cinder concrete could be used. Compared to other binding materials, the tensile strength of concrete is relatively low. Concrete is less ductile.
