Examples of the experiments
The performances of the novel high-performance ecological artistic cement materials provided by the embodiments 1-4 and the performances of the traditional cement provided by the comparative examples 1-4 are verified through experiments.
The experimental method comprises the following steps: the novel high-performance ecological artistic cement materials provided by the embodiments 1-4 and the traditional cements provided by the comparative examples 1-4 are mixed with water to prepare the same standard sample, the standard sample is maintained in the same way, the concrete performance test method is adopted for testing, the test conditions are the same, and the test experiment results are shown in table 1.
TABLE 1 results of the experiment
As can be seen from the experimental results in the table 1, after the novel high-performance ecological artistic cement material provided by the embodiment of the application is made into slurry by adding water, the slurry has larger slump compared with the traditional cement of comparative examples 1-3, so that the novel high-performance ecological artistic cement material is more convenient for building repair construction, especially repair construction of cracks on the wall surface of a building. This novel high performance ecological artistic cement material is through the compressive strength of 7 days and 28 days after the maintenance, is not less than the compressive strength of the traditional cement that comparative example 1 ~ 3 provided, and most embodiments are higher than the compressive strength of comparative example even, and from this the explanation, its intensity of novel high performance ecological artistic cement material that this application embodiment provided can satisfy the construction of building restoration, has higher intensity. Compared with the bending strength of the traditional cement provided by the comparative examples 1-3, the bending strength of the novel high-performance ecological artistic cement material provided by the embodiment of the application after being maintained for 7 days and the bending strength of 28 days are obviously improved, and the improvement of the bending strength greatly helps to repair buildings, especially the walls of the buildings, can improve the bending resistance of the walls, and helps to reduce the generation of cracks. Furthermore, the bonding strength of the novel high-performance ecological artistic cement material provided by the embodiment of the application and plastering mortar is stronger than that of traditional cement provided by comparative examples 1-3. The brick powder made of the building waste containing soil is added into the novel high-performance ecological artistic cement material, and the bonding strength of the ecological artistic cement material and the plastering mortar can be enhanced by the brick powder made of the building waste containing soil. This is also of great help to reduce the incidence of cracks at the repair.
Further, as can be seen from comparison between comparative example 4 and example 1, the flexural strength of the eco-artistic cement material is greatly improved by adding the brick powder containing soil to the eco-artistic cement material of example 1.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
