Application of Steel Fiber Reinforced Concrete in House Construction
Concrete is an indispensable construction material in house building. Steel fiber reinforced concrete refers to the mixing of a certain amount of steel fibers into concrete, which is then combined through stirring to ultimately form steel fiber reinforced concrete. It is a high-performance fiber reinforced concrete. Steel fiber reinforced concrete has greater tensile strength compared to traditional concrete, has better durability, and possesses many other advantages. The role of steel fiber reinforced concrete in house construction has become very prominent.
So, how is steel fiber reinforced concrete applied in house construction? What application technologies are used? Below, we will provide a brief analysis from several aspects for your reference.
Application of Steel Fiber Reinforced Concrete in Wall Construction
There are two main methods for applying steel fiber reinforced concrete in house wall construction:
Dry construction
This method involves connecting prefabricated metal fixtures to the original wall, using steel fiber reinforced concrete to make thin wall panels that act as a covering layer for the insulation layer.
Wet construction
Wet construction uses the cement mortar material of steel fiber reinforced concrete, applying it to the insulation layer of the wall made from EPS boards, forming a wet covering layer, which then creates a composite wall with EPS boards.
Whichever method is used, the construction results are excellent. Using steel fiber reinforced concrete for wall construction also speeds up the process of wall panel construction. This is greatly beneficial for the forward development of the house construction industry.
Application of Steel Fiber Reinforced Concrete in Waterproofing and Flooring
Steel fiber reinforced concrete has a relatively good waterproofing effect and can be widely used in flooring construction in house building. For instance, warehouses holding a large amount of heavy goods often experience heavy impact on the floor, and the goods need a dry environment. The requirements for the floor include being wear-resistant, not easily cracked, and not prone to deformation, all of which conditions steel fiber reinforced concrete can meet.
The most troubling issue in house construction is roof leakage. The use of steel fiber reinforced concrete can prevent the appearance of cracks, thereby reducing instances of roof leakage.
Application of Steel Fiber Reinforced Concrete in Transfer Beams
House construction also includes high-rise building construction, wherein the construction design of transfer beams is encountered. In the construction of transfer beams, the application of steel fiber reinforced concrete is very important. The load-bearing capacity of the transfer structure is relatively heavy, and in most cases, transfer beams are eccentrically tensioned members that bear a large shear force, requiring high resistance to shear and cracking. The crack resistance of steel fiber reinforced concrete is much higher than that of ordinary concrete, thus playing an important role in the construction of transfer beams.
Many high-rise buildings now use steel fiber reinforced concrete in the construction of transfer beams, and the results are impressive. The shear resistance is generally 44% higher than construction without steel fiber reinforced concrete. Therefore, using steel fiber reinforced concrete in the construction of transfer beams in high-rise buildings is a time-saving, labor-saving, and cost-effective construction method.
Application of Steel Fiber Reinforced Concrete in Columns and Shear Walls
Adding steel fibers to concrete can improve its performance, significantly enhancing the ultimate compressive strain at the compressed edges of columns, thereby increasing the ductility of columns. In the frame-shear wall and frame simple structure of high-rise buildings, the span-to-height ratio of coupling beams in linked walls is generally small, making them prone to brittle shear failure. Adding a certain amount of steel fibers can effectively improve the bonding and plastic conditions of the concrete in the coupling beams, enhancing seismic performance.
