SEM observation of fracture surfaces further proves that basalt fiber still exists inside matrix at elevated temperatures, constrains crack propagation and transfer stress, thus contributes to the increased tensile and compressive strength. Although superimposed basalt fiber volume fraction improves the compressive and tensile …

In this study, basalt aggregates obtained from different quarries were examined in terms of their physical and mechanical properties. The results were compared with the current granular material specifications in force. When basalt aggregates are used as crushed-stone, the flakiness rate is found relatively high due to their glassy structure.
Fig.1 shows the compressive strength details of basalt and glass fiber reinforced concrete. It shows that the compressive strength of glass and basalt fiber reinforced concrete was increased considerably when comparing to control mix. But there is no maximum difference in compressive strength of glass and basalt fiber concrete.

Continuous basalt fibres (CBFs) produced directly from natural basalt seldom achieve adequate performance with high tensile strengths. Thus, formulation optimization is a key component of technological innovation in the field of CBFs.
To do this, we evaluated the physical (porosity, permeability) and mechanical (strength) properties of basaltic rocks at Pacaya Volcano (Guatemala) through a variety of laboratory experiments, including: room temperature, high temperature (935°C), and cyclically-loaded uniaxial compressive strength tests on as-collected and thermally …
Typical values of strength parameters for intact basalt at ambient temperature (20°C) and negligible confining pressure are Young's modulus, 78±19 GPa; Poisson's ratio, …
Basalt fiber (BF) is an excellent reinforcement material thanks to its high mechanical strength, ecological compatibility, low cost, and excellent chemical resistance [1].

The main mechanism is that after basalt fiber is added, basalt fiber exerts its high tensile strength characteristics, and then shows the overall strength of basalt fiber-reinforced concrete. At the same time, basalt fiber-reinforced concrete has better anti-cracking advantages compared with traditional concrete, and its thermal and chemical ...
The aim of this study is to understand the strength behaviour and fragment size of rocks during indirect, quasi-static and dynamic tensile tests. Four rocks with different lithological characteristics, namely: basalt, granite, sandstone, and marble were selected for this study. Brazilian disc experiments were performed over a range of strain rates …
This study investigates the potential use of basalt powder as a sole precursor or blended in high amounts in slag-based alkali-activated systems. Eight alkali-activated mixes are prepared and comprehensively analyzed to determine the compressive strength development and microstructural characterization of basalt powder-based and …

This study investigates the predictive capabilities of Artificial Neural Network (ANN), Random Forest (RF), and Random Tree (RT) models for determining the compressive strength (CS) of concrete, with a specific focus on the individual and hybrid effects of Basalt Fiber (BF) and Polypropylene Fiber (PPF) on CS. The RF model …
From the analysis results, it can be found that the effect of basalt fiber on the compressive strength of RPC is limited, and the high content of basalt fiber even reduces the strength of RPC obviously. This is because the basalt fiber mainly improves the tensile stress and crack resistance of concrete, solves the fragile tensile response of ...

Among them, compressive strength is the most important reference index in the mechanical properties of concrete, which significantly impacts the safe use of concrete. Therefore, the accurate and rapid prediction of the compressive strength of basalt fiber concrete (BFRC) has essential application value in practical engineering applications.
