Summary
Basalt fibers (BFs) enhance concrete
Area of Science:
- Materials Science
- Civil Engineering
- Construction Materials
Background:
- Concrete's low tensile capacity leads to brittle failure.
- Fiber reinforcement, particularly basalt fibers (BFs), is investigated to improve tensile strength (TS) and ductility.
- BFs offer benefits like high strength, elastic modulus, and thermal stability.
Purpose of the Study:
- To comprehensively review the effects of basalt fibers (BFs) on concrete properties.
- To consolidate scattered information on BFs in concrete for easier understanding.
- To identify optimal BFs incorporation and research gaps.
Main Methods:
- Literature review of existing research on basalt fibers in concrete.
- Analysis of flow properties, strength properties, and failure modes.
- Identification of optimal BFs content and its impact.
Main Results:
- Basalt fibers (BFs) significantly enhance concrete's strength properties and ductility.
- BFs negatively impact concrete's flowability.
- Optimal BFs content is crucial, typically between 0.5% and 1.5%, as higher doses can reduce strength due to poor flowability.
Conclusions:
- Basalt fibers (BFs) are effective in improving concrete's tensile capacity and ductility.
- Careful consideration of BFs content is necessary to balance strength enhancement and workability.
- Further research is needed to address identified gaps before real-world application.

Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

01:22Fatigue Strength of Concrete
254
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

01:16Tensile Strength Considerations of Concrete
183
Considering the tensile strength of concrete involves recognizing that the theoretical strength of cement paste can be up to a thousand times higher than what is observed in practical applications. This significant discrepancy is largely attributed to the presence of microscopic cracks within the concrete. These cracks tend to amplify stress at their tips when a load is applied, a phenomenon explained by Griffith's theory of brittle fracture.

01:23Behavior of Concrete Under Compressive Load
250
Concrete exhibits specific behaviors under different compressive loads. Understanding this is crucial for understanding its structural integrity. When concrete undergoes uniaxial compression, it tends to develop cracks that run parallel to the direction of the force. These parallel cracks stem from localized tensile stresses that occur perpendicular to the compression direction. Additionally, angled cracks may appear due to the formation of shear planes.

01:25Reinforcements in Concrete
141
Reinforced concrete is a composite material used extensively in construction, combining the compressive strength of concrete with the tensile strength of steel. This synergy is essential as concrete, while excellent at resisting compression, is weak under tension. Steel bars, or rebars, are embedded in the concrete to handle these tensile forces. The choice of steel is strategic; it shares a similar coefficient of thermal expansion with concrete, which ensures uniformity in response to...

01:21Impact Strength of Concrete
306
Impact strength in concrete is a critical measure that reflects the material's capability to endure the forces applied during pile driving and when supporting machinery foundations that experience impulsive loads. It is also essential when handling precast concrete components to prevent accidental damage. The impact strength is assessed by observing the concrete's resistance to repeated impacts and energy absorption capacity. A key indicator of significant damage to concrete is when it...
