The components and amounts of the components of the floor materials in examples 1 to 3 and comparative examples 1 to 4 are shown in Table 1 below. The slurries obtained in examples 1 to 3 and comparative examples 1 to 4 were tested for fluidity, mechanical properties and dimensional change rate, the fluidity was tested according to the standard GB/T50448-2015 "cement-based grouting material application Specification", the mechanical properties and dimensional change rate were tested according to the standard JC/T985-2017 "cement-based self-leveling mortar for ground", the dimensional change rate was used to characterize crack resistance, and the smaller the dimensional change rate was, the better the crack resistance was.

Table 1 components and amounts of each component of the floor materials in examples and comparative examples
Table 2 performance test data for slurries and wear-resistant terraces of examples and comparative examples
As can be seen from table 2, the construction slurries of examples 1 to 3 have excellent workability, mechanical properties, crack resistance and wear resistance, and the wear-resistant terraces of examples 1 to 3 have excellent wear resistance and surface hardness. As can be seen from comparison of example 1 and comparative example 1, too low an amount of cement reduces the mechanical properties, crack resistance and wear resistance of the slurry. As is clear from comparison of example 2 and comparative example 2, the use of dolomite aggregate as the wear-resistant aggregate deteriorated the wear resistance of the wear-resistant floor surface. As is clear from comparison of example 2 and comparative example 3, when the amount of steel fiber is reduced, the mechanical properties of the slurry are deteriorated and the wear resistance of the wear-resistant floor is also reduced. As is clear from the comparison between example 2 and comparative example 4, example 2 using a high-silicon aggregate can significantly improve mechanical properties and abrasion resistance as compared with comparative example 4 using a non-high-silicon aggregate.
The steel fibers and the sizing agent can jointly construct a three-dimensional network structure, and the three-dimensional network structure can increase the stability of the sizing agent and is beneficial to promoting the improvement of the mechanical properties of the sizing agent. But the dosage of the steel fiber should be within a specific range to better enhance the mechanical property. When the consumption of steel fibers is too low, the density of the constructed three-dimensional network structure becomes small, and the effect of increasing the stability of the slurry is limited. When the consumption of the steel fibers is too high, the steel fibers in the slurry are easy to sink, so that the steel fibers are unevenly distributed, the tensile strength is also not beneficial to improvement, and the other mechanical properties and the wear resistance are reduced. Only when the steel fiber is used in proper amount and can be uniformly distributed in the slurry, the mechanical property and the wear resistance can be obviously improved. Whether the steel fibers can be uniformly distributed in the slurry is influenced by the cement amount and the cement ratio in addition to the amount of the steel fibers, so that a specific amount of the steel fibers, a specific amount of cement and a specific cement ratio are required to be blended.
The simultaneous addition of the high-silicon aggregate and the steel fiber also has a synergistic effect on mechanical properties and wear resistance. Referring to comparative example 3, high silicon aggregate and steel fiber are added at the same time, but the amount of steel fiber is too low, and the ratio of steel fiber to powder is only 0.03:1, a step of; see also comparative example 4, in which a specific amount of steel fiber was added, but a common aggregate was used. The mechanical properties of comparative example 3 and comparative example 4 are comparable, but the abrasion resistance of comparative example 3 is significantly worse. In example 2, the specific amount of steel fiber and high-silicon aggregate are added at the same time, and as can be seen from table 2, the mechanical properties and wear resistance of example 2 are significantly improved compared with those of comparative examples 3-4, and the combination of the specific amount of steel fiber and high-silicon aggregate produces synergistic effect.
