Examples
Embodiment 1
[0043] Configure solid mixtures:
[0044] In this example, the material to be cured is a construction waste, and the particle grade of the construction waste is like figure 1 As shown, less than 0.075 mm has more than 20% of total quality. First, the construction waste is mixed with the active magnesium oxide, and 30 g of active magnesium oxide is added to each 270 g of construction, that is, 10% magnesium oxide content. The fibers selected for the present embodiment are basalt fibers, the length is 12mm, the specific gravity is 2.80, the average diameter is 0.013mm, the fracture tensile strength is 4150 MPa, the Young's modulus is 93 GPa, the limit extension is 2.56, the volume of the fiber is 0.1%.
[0045] The basalt fibers were twisted, and the active magnesium oxide was incorporated into the mixture of the construction waste, stirred evenly.
[0046] Configure liquid mixture:
[0047] Preparation ATCC 1376 NH in proportion 4 -YE medium, and sterilized in a sterilized pot, 0...
Embodiment 2
[0052] The present embodiment is substantially the same as in Example 1, and the difference is only to 0.3 vol% of the amount of basalt fiber. Specifically, such as Table 1.
Embodiment 3
[0054] The present embodiment is substantially the same as in Example 1, and the difference is only 0.6 vol% to the basalt fiber. Specifically, such as Table 1.
