Problems solved by technology
[0003] However, general asphalt concrete has very serious safety problems in the fire environment. It is easy to melt and burn when the temperature is too high, which brings safety hazards. Due to the poor fluidity of asphalt during processing, It is also not convenient for stirring and mixing and discharging collection, thereby reducing production efficiency

The invention discloses flame-retardant asphalt concrete. The flame-retardant asphalt concrete is formed by mixing asphalt modified by a magnesium hydroxide flame retardant and concrete according to a mass ratio of 1: 3. The processing method of the flame-retardant asphalt concrete comprises the following steps: S1, preparing flame-retardant asphalt; and S2, preparing the flame-retardant asphalt concrete. The flame-retardant concrete formed by mixing the asphalt modified by the magnesium hydroxide flame retardant and the concrete can be used on the inner walls of various safety channels, has an excellent fireproof effect and improves the safety.
Description
technical field [0001] The invention belongs to the technical field of concrete, in particular to flame-retardant asphalt concrete and a processing method thereof. Background technique [0002] Asphalt concrete is widely used in road and building construction. Among them, asphalt as a mixture can increase the structural strength, mainly in two aspects: one is the bonding force of the cement formed by asphalt and mineral powder; the other is the aggregate particles The internal frictional resistance and locking force between them. The huge surface area of the fine particles of mineral powder makes the asphalt material form a thin film, thereby improving the bonding strength and temperature stability of the asphalt material. [0003] However, general asphalt concrete has very serious safety problems in the fire environment. It is easy to melt and burn when the temperature is too high, which brings safety hazards. Due to the poor fluidity of asphalt during processing, It is...
