“…Zhe Huang et al investigated the influence of technology disruption on the mechanical properties of BFRC, in the period from the initial to the final setting, and the mechanism of action [23]. The influence of this violation on the process of sulfate erosion of concrete was assessed via a test for sulfate erosion, obtaining ultrasonic data on the process of its damage.…”

Increasing the bearing capacity of reinforced concrete structures, reducing material consumption, and ensuring quality are critical in modern construction. The article presents an experimental study of the ultimate compressive strains of short fiber basalt reinforced concrete columns and provides recommendations for increasing the bearing capacity using steel reinforcement bars with greater strength. The columns were tested in an upright position using a hydraulic press. Strains were measured with dial indicators and a strain gauge station. It was shown that the addition of 10% coarse basalt fiber increased the ultimate compressibility of concrete on ordinary crushed stone by 19.8%, and expanded clay concrete by 26.1%, which led to the strain hardening of concrete under compression by 9.0% and 12%, respectively. Ultimate compressive strains in fiber-reinforced concrete short columns with combined reinforcement increased 1.42 times in columns on a lightweight aggregate and 1.19 times on heavy aggregate. An increase in the ultimate compressibility of concrete makes it possible to use steel reinforcement with greater strength in compressed elements as the concrete crushing during compression occurs primarily due to the reaching of critical values by tensile stresses in the transverse direction. This makes it possible to manufacture structures with a higher load-bearing capacity and less material consumption. A practical example of the application of the proposed approach is given.

“…Relevant studies show that the optimal fiber volume content of basalt fiber concrete is 0.1%. 34,37,38 The main reason for this is that a large number of fiber cannot be well dispersed in concrete, but agglomerate, which leads to the increase of porosity in the concrete and the decrease of adhesion force. So a large number of fiber can weaken the mechanical property of concrete to a certain degree.…”

The dynamic compression test was carried out on basalt fiber reinforced early strength concrete (BFRESC) with ages of 4–24 h by the split Hopkinson pressure bar (SHPB) test system. The effects of curing age and basalt fiber content on dynamic mechanical properties of ESC was analyzed. The result shows that the dynamic compressive strength and specific energy absorption of BFRESC at early ages increase continuously with the increase of fiber content. The dynamic compressive strength of concrete at the early ages increases exponentially with the strain rate. With the increase of curing age, the strain rate sensitivity of dynamic compressive strength of concrete increases gradually, and the strain rate sensitivity of dynamic compressive strength of BFRESC with fiber content of 0.1% is the strongest. The specific energy absorption of concrete at early ages increases linearly with the strain rate. With the increase of curing age, the strain rate sensitivity of specific energy absorption of concrete increases gradually, and basalt fiber can enhance the strain rate sensitivity of specific energy absorption of concrete. Based on the comparison with the formula for dynamic increase factor (DIF) calculation provided by Comite Euro‐International du Beton (CEB), etc., a model of DIF based on the increase of curing age is proposed.

In order to speed up the construction progress of the project, the pouring of concrete is often carried out at the same time as blasting and excavation, resulting in various vibration interference to the concrete. These vibrations damage the performance and service time of the concrete. Therefore, it is especially important to study the anti-disturbance performance of concrete. By analyzing the research results of domestic and foreign, the influence law of disturbance on concrete was summarized and its action mechanism was discussed. The evaluation methods and improvement measures for the anti-disturbance performance of concrete were summarized. In addition, the deficiencies in the previous studies were pointed out in this paper.
