First of all, it is confirmed that ordinary concrete slabs are important building materials. For your specific problem, it is recommended that you should search on the Internet or consult a professional architect.

Fiber cement board, also known as fiber reinforced cement board, is a cement flat plate for construction produced with fiber and cement as the main raw materials.

Fiber cement board is mainly used in building ceilings, partition walls and other parts, and can also be used for steel structure exterior walls and steel structure floors. It is often used for fire retardant in cable projects in various power plants, chemical enterprises and other electricity-intensive places in China. It is also the best fireproof and flame retardant material for interior decoration of large shopping malls, hotels, guesthouses, document halls, closed clothing markets, light industry markets, theaters and other public places.

The fiber cement version is a complete replacement for gypsum board, and is much better in terms of strength, fire and moisture resistance.

Fiber cement veneer can be used as an alternative to stone for wall decoration and ceramic tiles for wall decoration. Because its specifications are generally 1220*2440, it can be put on the wall as a whole, so the wall decoration has the solid color effect of large blocks that stone and ceramic tiles cannot do.

Fiber cement veneer is widely used in Europe, especially in Japan.

The use of fiber cement board for ceiling or partition.

Concrete slab refers to the concrete slab in the building, which is a professional term for construction.

Reinforced concrete slabs, slabs made of reinforced concrete materials, are the basic structures or components in housing construction and various engineering structures, often used as roofs, floors, platforms, walls, retaining walls, foundations, floors, pavements, pools, etc., with a wide range of applications.

Reinforced concrete slabs are divided into square slabs, round slabs and special-shaped slabs according to the plane shape. According to the force mode of the structure, it is divided into one-way plate and two-way plate. The most common are one-way plates, four-sided two-way plates, and beamless slabs supported by columns. The thickness of the plate should meet the requirements of strength and stiffness.

Concrete, refers to concrete, in engineering design and construction, often abbreviated as "concrete" three words. The pinyin is tóng, and the glyph structure is left and right. Common phrases are concrete car:

For example, in order to meet the needs of the construction company as soon as possible, he bought a concrete truck to improve work efficiency. Concrete: The person who pours concrete into a structure, building, and structure, such as a concrete worker, is an indispensable technical talent for construction companies.

It is a slab formed by supporting the formwork, and then pouring concrete, after curing. Concrete can be commercial mixed or on-site mixed concrete.

"Concrete" means concrete, and concrete slab is concrete slab.

The bottom reinforcement of the plate is the tensile rib laid under the plate, and the top reinforcement of the plate is the reinforcement on the upper part of the plate, which is mainly to prevent cracking, so the difference is the difference in function. However, there is no difference in the configuration of the steel bars at the bottom of the slab and the top of the slab on the site, because the thinnest steel on the market is round 4, so there is no need to adjust the steel bars at the top of the slab. Generally, it is called the bottom steel bar and the plate surface steel bar, and these two kinds of steel bars mostly appear on the cast-in-place plate reinforcing steel bar.

For example, the reinforcing steel bar used in the manhole and folding plate on the roof belongs to the bottom of the slab, because the reinforcing steel bar is placed at the bottom of the cast-in-place slab. For example, if the starting point of the bay window is cantilevered, it should be placed in the same position as the negative reinforcement (iron) of the cast-in-place slab, which is called the plate surface stiffener.

The bottom rib of the plate is the tensile rib laid under the plate; The top reinforcement of the plate is the steel bar in the upper part of the plate, which mainly bears the tensile force of the plate surface generated by the negative bending moment of the plate support and the negative moment reinforcement that prevents the cracking of the plate surface; The top steel bar of the slab is also called the plate surface steel bar. Generally, the steel bar at the bottom of the slab should be fully configured. The configuration of the top steel bar of the plate is divided into several situations, the negative bending moment of the plate is small and the plate surface does not have anti-cracking requirements, the plate surface steel bar is only configured with the plate support of the negative bending moment part, and the central part of the plate is not equipped with the steel bar; If the plate surface has anti-cracking requirements, the anti-cracking steel bar on the plate surface can be configured separately, and the negative moment bar on the plate surface can be lapped and tied according to the requirements of the specification.

If the negative bending moment of the plate surface support is large and the reinforcement required for full surface crack resistance is also high, the negative moment reinforcement of the plate surface can be fully covered to form a double-layer reinforcement. At present, most of the concrete cast-in-place slabs are two-way stressed plates, and in this case, they are configured into double-layer two-way configuration reinforcements, also called double-layer two-way reinforced concrete slabs. ‍‍

In concrete, sand and stone play the role of skeleton and are called aggregates; Cement forms a cement slurry with water, which wraps around the surface of the aggregate and fills its voids. Before hardening, the cement slurry plays a lubricating role, giving the mixture a certain workability and facilitating construction. After the cement slurry hardens, the aggregate is cemented into a solid whole.
