Example 4
The abrasion resistance, the compression resistance and the permeability of the multifunctional color concrete structure obtained in the embodiment 1-3 are detected and compared through a humidity sensor and a strain sensor, wherein the detection data of the permeability detect the humidity of the multifunctional color concrete structure at the same time point through single water spraying amount, and the permeability is calculated through the detected humidity value; after the detection data of the strain sensor are subjected to the same number of times of pressure with the same value, the compression resistance is calculated through the bit variable value obtained through detection; the abrasion resistance of the color layer 4 was calculated, and the calculation result was shown in the following table:
| abrasion value (g/cm) 2 ) | Compressive strength (MPa) | Coefficient of water permeability (mm/s) | |
| Example 1 | 0.250 | 47.5 | 8.0 |

| Example 3 | 0.125 | 52.5 | 6.5 |
The more the aggregate and cement are added, the greater the compressive strength, but the smaller the water permeability coefficient; the smaller the abrasion value, the more abrasion resistant, the more styrene-butadiene rubber is added, wherein the smaller the abrasion value of the color layer 4 is; for the purpose of average wear resistance, compression resistance and permeability, therefore, the best embodiment of example 2 is selected, and in practical construction, the best embodiment can also be selected according to the construction requirements.
In the above examples, the vulcanization accelerator can vulcanize rubber under certain conditions, namely, the linear molecular structure of the rubber is changed into a three-dimensional net mechanism through the bridging of the vulcanizing agent, so that the mechanical and physical properties of the rubber are obviously improved; wherein the tetramethylthiuram disulfide is mainly suitable for vulcanization of styrene butadiene rubber.
In addition, the sulfur in the tetramethylthiuram disulfide can also promote the effect of the sulfide series light-storage self-luminous material, and further increase the range of the excitation light wavelength of the sulfide series light-storage self-luminous material.
In the above embodiment, a sulfide-series light-storage type self-luminous material of a color may be selected depending on the site situation, in which there are ZnS: cu series, caS: bi series, and CaS: eu series, which emit light in yellow-green.
It should be noted that, the sulfide series light-accumulating self-luminous material is also called as a light-induced ultra-long afterglow light accumulating material, a non-radioactive light accumulating material, a non-power self-luminous material and the like, and after the material actively absorbs and accumulates visible light such as sunlight, lamplight, ultraviolet light, stray light and the like for 5-10min, the material can continuously emit light for more than 12h in the dark, so that the color layer 4 has the appearance and performance of the original material, has a special decorative effect of noctilucent light emission, and plays roles of attractive appearance, guidance, indication or warning.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
