Performance testing
The XRD pattern of the recovered stone powder of the cement plant aggregate line used in example 1 was measured, and the result is shown in fig. 1.
As can be seen from figure 1, the main component of the stone powder recovered from the aggregate production line of the cement plant is calcium carbonate.
The environment-friendly high-strength waterproof exterior wall putty prepared by the method in the embodiments 1-6 is subjected to drying time, sanding property, alkali resistance, water resistance, bonding strength, initial drying crack resistance and water absorption capacity experiments according to detection items, detection methods and detection indexes of the industrial standard JG-T157-2009 putty for building exterior walls. The test results are shown in table 1 below.
TABLE 1 Performance characterization results of the different examples
As can be seen from Table 1, the detection results of the environment-friendly high-strength waterproof exterior wall putty prepared in the embodiments 1 to 6 all meet the requirements of the industry standard JG-T157 & 2009 putty for building exterior walls. Among them, the adhesive strength of example 6 and the adhesive strength after the freeze resistance test were higher than those of the other examples. This formulation is therefore an excellent formulation for the purposes of the present invention.
After the product of the invention is added with a large amount of various solid wastes, excellent exterior wall putty with good construction performance, high bonding strength, alkali resistance and water resistance can be obtained, and the environment-friendly high-strength water-resistant exterior wall putty prepared after adding the slag has similar performance to the environment-friendly putty prepared without adding the slag, so the product can replace exterior wall paint and is more environment-friendly.
