## 4 Conclusions  
In this experiment, the YAW-2000C constant stress pressure experimental machine was used to carry out the static compressive test, and the split-Hopkinson pressure bar was used to carry out the dynamic impact test, and the static compressive strength and dynamic compressive strength of ordinary concrete and basalt fiber-reinforced concrete under various of heating temperatures and cooling methods (air-cooled method and water-cooled method) were investigated. Through the experimental data, the conclusions are as follows:  
(1) With the increase of the temperature, the physical parameters of the two concretes changed, such as mass, wave velocity, and color. The mass loss of two concretes increases with the increase of temperature. The wave velocity of two concretes is descending with the increase of the temperature, but the mass loss rate of basalt fiber-reinforced concrete is less than ordinary concrete. Thus, high temperatures produce a detrimental effect on the mechanical property of concrete and the mechanical property of basalt fiber-reinforced concrete is better than ordinary concrete. Moreover, with the temperature increasing, the color of concrete gradually changes from dark blue to red. When the temperature reaches 800 \({}^{\circ}\)C, the concrete gradually turns white. However, compared with ordinary concrete, the color change with the temperature of basalt fiber-reinforced concrete shows hysteresis.

(2) The static compressive strength of both ordinary concrete and basalt fiber-reinforced concrete increases when the temperature is 25-200 \({}^{\circ}\)C, and the strength reaches a peak when the temperature increases to 200 \({}^{\circ}\)C. After, the static compressive strength begins to decrease with the increase of the temperature. When the temperature increases to 400 \({}^{\circ}\)C, the static compressive strength of the two concretes is lower than at room temperature under the same conditions, and when the temperature rises to 800 \({}^{\circ}\)C, the concretes lose their bearing capacity. However, at the same temperature, the static compressive strength of basalt fiber-reinforced concrete is bigger than ordinary concrete. In addition, the static compressive strength of the concretes after cooling in air is greater than that after cooling in water, and the fracture for the water-cooled specimen is bigger than for the air-cooled specimen at the same heating temperature. (3) The dynamic compressive strength of the concretes is affected by the loading rate and temperature. The dynamic compressive strength of concretes is bigger than the static compressive strength of concrete at the same conditions and increases with the increase of the loading rate. At the same loading rate, the dynamic compressive strength of basalt fiber-reinforced concrete is bigger than ordinary concrete. Within t 25-200 \({}^{\circ}\)C, the strength increases when the temperature increases and reaches a peak when the temperature increases to 200 \({}^{\circ}\)C. After, the strength begins to decline with the further increase of the temperature. At the same loading rate and heating temperature, the dynamic compressive strength of basalt fiber-reinforced concrete is bigger than ordinary concrete. In addition, the crushing form of concrete specimens cooled by air is better than those cooled by water; however, in the same conditions, the crushing form of basalt fiber-reinforced concrete is better than ordinary concrete. (4) The addition of basalt fiber to concrete can significantly improve the mechanical property of concrete. The use of basalt fiber-reinforced concrete can largely enhance the fire resistance of the structure and improve the security after being subjected to conflagration or other high-temperature conditions.
