What are Concrete Forms?

Reinforced concrete (English: Reinforced Concrete or Ferroconcrete) is often referred to simply as reinforced concrete (tong) in engineering. It refers to a composite material that works by adding reinforced mesh, steel plates or fibers to concrete to improve the mechanical properties of concrete. It is the most common form of reinforced concrete.

The invention of reinforced concrete appeared in modern times. It is generally believed that the French gardener Joseph Monier (en: Joseph Monier) invented the reinforced concrete in 1849 and obtained it in 1867. Patent for reinforced concrete beams and columns of guardrails. In 1872, the world's first reinforced concrete structure was completed in New York, USA. A brand-new era in the history of human architecture has begun. Since 1900, reinforced concrete structures have been used on a large scale in engineering circles. 1928, a new form of reinforced concrete structure

The reason why reinforced concrete can work together is determined by its own material properties. First of all, the reinforcement and the concrete have approximately the same line

Concrete is cement (usually

The content of reinforced concrete in reinforced concrete is usually very small, ranging from 1% (more common in beams and slabs) to 6% (more common in columns) of the member's cross-sectional area. The cross section of the reinforcement is round. In the United States from 0.25 to 1 foot in 1 / 8-foot increments; in Europe from 8 to 30 mm in 2 mm increments; in mainland China from 3 to 40 mm, divided into 19 classes. In the United States, there are two types of steel: 40 steel and 60 steel. The latter has higher carbon content, higher strength and stiffness, but is difficult to bend. In corrosive environments, electroplated, epoxy-coated, and stainless steel rebars are also used.

In wet and cold climates, structures that may use deicing salt on reinforced concrete pavements, bridges, parking lots, etc., should be used.

Steel plate concrete

During the construction of steel plate concrete, workers welded steel plate members on site, saving

Fiber concrete is mainly used for shotcrete construction, but it can also be used for ordinary concrete construction. Steel fiber and glass fiber are the most commonly used fibers, and their cost is not much more expensive than artificially banding reinforced concrete.
Carbon fiber is also very suitable for reinforcing concrete, but it is expensive, so it is generally used as a reinforcement remedy for failed reinforced concrete.
