example 1

[0028]Put sodium alginate and water in a No. 1 beaker at a mass ratio of 1:100, stir with a glass rod for 20 minutes, then place the No. 1 beaker in a magnetic stirrer with a digital speed measurement and constant temperature at a temperature of 85°C and a speed of 500r Under the condition of heating and stirring for 60 minutes, the sodium alginate solution is obtained; silicon nitride whiskers and hydrofluoric acid with a mass fraction of 35% are placed in a reaction kettle at a mass ratio of 1:20, and the rotational speed is 300r / min. Under the condition of mixing and soaking for 30 minutes, filter to obtain No. 1 filter cake, then wash No. 1 filter cake with ammonia water with a mass fraction of 30% until the washing liquid is neutral, and then place the washed No. 1 filter cake in In an oven, at a temperature of 110°C, dry to constant weight to obtain pretreated silicon nitride whiskers. In parts by weight, 30 parts of pretreated silicon nitride whiskers, 3 parts of seconda...

example 2

[0030] The rice husk fiber is pulverized in a pulverizer, and passed through a 120-mesh sieve to obtain refined rice husk fiber. In parts by weight, 30 parts of refined rice husk fiber, 3 parts of biogas slurry, and 3 parts of mass fraction are 0.5% 40 parts of water were placed in a fermentation tank, and the temperature was 35°C, and the rotation speed was 500r / min. After 5 days of mixed fermentation, it was filtered to obtain pretreated fibers. The pretreated fibers were mixed with 40% of The sodium hydroxide solution is placed in a mixing tank according to the mass ratio of 1:20, and at a speed of 500r / min, after mixing and soaking for 2 hours, the filter residue is obtained, and then the filter residue is frozen in liquid nitrogen to obtain a frozen block, and then the The frozen block is pulverized in a pulverizer, passed through a 240-mesh sieve to obtain a pulverized slag, and then the pulverized slag is placed at room temperature until the pulverized surface is complet...

Description

technical field [0001] The invention discloses a modified fiber asphalt mortar, which belongs to the technical field of building materials. Background technique [0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some polymers and wood cellulose are added; different structures are formed by mixing these materials with different qualities and quantities. And have different mechanical properties. Asphalt mixture is a general term for the mixture made by mixing mineral aggregates and asphalt binder. According to the material composition and structure, it can be divided into continuous gradation and discontinuous gradation mixture. According to the mineral material gradation composition and porosity, it can be divided into dense gradation, semi-open gradation and open gradation mixture. According to the size of the nominal maximum particle size, it can be divided into extra-coarse type (nominal ma...
