[0028] like Figure 1 to Figure 7 Shown, present embodiment discloses a kind of preparation method of high-performance fiber concrete with antibacterial property, it comprises the following steps:
[0029] Step 1, cutting materials, cutting the rice stalks recycled in the farmland into 30-50mm long straw knots.
[0030] Step 2, scrapping, the straw joints are smashed to form straw fibers with a pulverizer.
[0031] Step 3, straw fiber pretreatment, the straw fiber of step 2 and the NaOH solution that mass fraction is 1% are mixed in the constant temperature water bath pot and soaked, wherein, the mass ratio of straw fiber and NaOH solution is 1:10, constant temperature water bath pot Set the temperature to 80°C, then continuously stir with a magnetic stirrer for 30 min, and control the rotational speed of the magnetic stirrer to 300 r / min.
[0032] In this step of this embodiment, the surface of the rice straw stalk is uneven, with many thorny structures attached thereto. A...
