Mechanical Properties and Failure Mechanisms of Fiber-Reinforced Concrete: Influence of Fiber Type and Content
Concrete is the most widely used construction material. It offers numerous advantages, including its widespread availability, simple production process, low cost, and ease of application. It's extensively used in various fields such as buildings, roads, bridges, tunnels, and hydraulic engineering. As a large number of engineering projects have developed, the demands on concrete's performance have also gradually increased. Consequently, the shortcomings of traditional concrete, such as insufficient tensile strength, poor crack resistance, and volume instability, have become apparent. Therefore, improving the performance of concrete has consistently been one of the key research directions in civil engineering.
Diverse Demands for Basalt Fiber Products
There are many products related to basalt fiber, such as basalt cloth, basalt yarn, etc. Thanks to the characteristics of basalt fiber, these products also have excellent performance in various industries.
Application of Basalt Fiber Composites in Civil Engineering
In the field of civil engineering, concrete structures are an extremely important component. However, with the development of the construction industry, the problem of construction waste is becoming increasingly prominent, with discarded concrete accounting for a considerable proportion. To achieve the low-carbon goal of the construction industry, the application of recycled concrete has gradually attracted attention. Nevertheless, recycled concrete has some defects in practical use, such as insufficient strength and poor durability.
Application of Basalt Fiber Reinforced Mortar in Residential Buildings
The exterior facade renovation of a residential complex utilized basalt fiber reinforced mortar. This project is located in a region with significant climate fluctuations, experiencing large temperature swings and strong humidity variations.
Overview of Basalt Fiber-Reinforced Plaster Mortar
Basalt fiber is primarily composed of silicon oxide, aluminum oxide, and iron oxide, with high levels of silicon oxide and aluminum oxide, giving it significant advantages in heat resistance and chemical corrosion resistance. Compared to glass fiber, basalt fiber does not contain harmful metal oxides, resulting in better chemical stability and excellent durability in corrosive environments like strong alkalis and strong acids.
Most Successful Modified Material: Glass Fiber Reinforced Modified Phenolic Resin (FX-501)
With the rapid development in the field of engineered glass fiber reinforced plastics, phenolic resin-based materials have been widely applied across various industries. This is due to their unique quality, high mechanical strength, and excellent performance. One of the most significant representative materials is phenolic glass fiber resin material.
Impact of unstable basalt raw material composition on actual production and improvement measures
Similar to carbon fiber and glass fiber, the production of continuous basalt fiber requires raw material standardization. There are significant differences in the quality and application effects of basalt fiber products from different regions. Even within the same region, variations exist in basalt from different parts of the same mine.
Application of Basalt Fiber Plain Weave Fabric in Floor Crack Repair
As buildings age, structural cracks have become a common and widespread issue. These cracks vary in type and form. Minor cracks not only affect a building's aesthetics and can lead to leaks, but more severe cracks can reduce the load-bearing capacity, stiffness, stability, integrity, and durability of the structure, potentially even leading to major quality incidents like total collapse. For minor cracks with low load-bearing requirements or small widths, basalt fiber plain weave fabric (BFRP) offers an economic and practical solution for reinforcement due to its superior cost-effectiveness.
From Raw Material to Application: Basalt Fiber
Basalt fiber boasts superior chemical, physical, mechanical, and high-temperature resistance properties. Continuous basalt fiber can be processed into roving, yarn, geotextiles, woven fabrics, chopped strands, needle felts, sleeving, and more, which are then applied in various fields.
Basalt Fiber: A Game-Changer for the Low-Altitude Economy
Basalt fiber boasts a simple manufacturing process and a single raw material. Crushed natural basalt ore is melted and homogenized in a high-temperature kiln (1400-1550℃), then cooled, drawn from a platinum-rhodium alloy spinneret, and finally wound into fiber. It exhibits excellent mechanical properties, temperature resistance, and chemical stability. Following ultra-high molecular weight polyethylene fiber, carbon fiber, and aramid fiber, basalt fiber is another high-performance fiber that China is prioritizing for development. Due to its pure natural, additive-free, and low-cost raw material, and its production process that generates no waste gas, basalt fiber has earned the reputation of "turning stone into gold." In recent years, it has been widely applied in various fields, including transportation, construction, environmental protection, chemical engineering, military, and aerospace.
