The invention also provides a preparation method of the oyster gray soil slurry for hollowing, cracking and anchoring in mural repair. In particular, the amount of the solvent to be used,
step S100, baking the oyster shells at 900-1100 ℃ for 2-3 h, deliquescing, and then finely grinding to obtain oyster ash;
step S200, mixing the oyster ash and the silt according to the ratio of 1: 3-1: 15 to obtain a mixture;
and step S300, adding water into the mixture and stirring until slurry with the fluidity of 200-240 mm is obtained.
And injecting the slurry into the to-be-repaired part of the mural in a pourable period, wherein the initial setting time is 1-2 h, the final setting time is about 11-16 h, and the time for forming a solidified body is 2-4 d.
And respectively weighing lime, silt and water according to the mass fractions in the above examples 1-3 and the reference group 1 for later use. Pouring water, lime and silt into a stirrer in sequence, starting the stirrer, stirring for 1 minute in a first speed mode, and stirring for 1 minute in a second speed mode after the materials are fully mixed; and finally, manually stirring the mixture evenly to prepare slurry for later use. It should be noted that the first speed is a high speed mode, the second speed is a low speed mode, and the first speed is greater than the second speed; the reason that water is added firstly and then oyster ash and silt are added is that calcium oxide in the oyster ash fully reacts and slowly emits heat, and if the oyster ash is added firstly and then the water easily causes the phenomena of insufficient reaction and overheating, the materials are not favorably mixed and reacted. Meanwhile, the speed of the stirrer can be flexibly adjusted by a person skilled in the art, the high-speed stirring is firstly carried out to ensure that all components of the material are fully mixed and contacted, and the low-speed stirring is carried out to prevent the material from being too hot, because the oyster ash contains a large amount of calcium oxide, the heat release is too large when meeting water.
The determination of the fluidity of the slurry refers to GB/T2419-2005 'determination method of fluidity of cement mortar'; the measurement of the setting time refers to the test results of GB/T1346-2001 'method for detecting the water consumption, setting time and stability of standard consistency of cement' which is shown in Table 1.
The slurries prepared in examples 1, 2, 3 and control 1 were divided into two groups, the first group of examples 1, 2, 3 and control 1 was prepared by using a steel test mold with a gauge of 40mm × 40mm × 160mm to prepare samples, and the second group of examples was prepared by using a steel test mold with a gauge of 40mm × mm × mm
Samples were prepared from test specimens made of steel having a gauge of 70.7mm × 70.7, 70.7mm × 70.7.7 mm in each of example 1, example 2, example 3 and control 1.
The test method of wave velocity and shrinkage rate is carried out by referring to JGJ/T70-2009 Standard for basic Performance test of building mortar, the test method of water content, density and porosity is carried out by referring to GB/T50123-1999 Standard for geotechnical test method, the test result is shown in Table 1, the test method of fracture resistance, compression resistance and freeze-thaw in age period of slurry solidified body is carried out by referring to GB/T17671-1999 method for testing the strength of cement mortar (ISO method), and the test result is shown in tables 2-5.
TABLE 1 basic physical Properties of slurries and slurry coagulates
TABLE 2 age flexural strength (/ MPa) of slurry solidified body
TABLE 3 age compressive strength (/ MPa) of slurry solidified body
TABLE 4 Freeze-thaw of the slurry solidified body, flexural strength (/ MPa) before and after the humiture test
TABLE 5 compressive strength (/ MPa) before and after freeze thawing, temperature and humidity test of the slurry solidified body
As can be seen from tables 1 to 5: after the lime and the silt are mixed according to different mass fractions, the porosity of the slurry solidified body is about 40%, and the compressive strength of the slurry solidified for 28 days is between 1.328MPa and 0.978 MPa. The fluidity of the slurry of control 1 was 185mm, which was not favorable for grouting operation.
The slurries of examples 1, 2 and 3 all had a fluidity of 200mm to 240 mm. The samples of the three groups of examples described above all satisfy the pourability, suitable strength and small shrinkage as reinforcing grout for hollowing, fissuring and anchoring. When the fluidity of the slurry is less than 200mm, the solid body shrinks less, but the slurry cannot be filled into the crack. When the fluidity of the slurry is more than 240mm, the shrinkage of the slurry solidified body is larger (more than or equal to 2.15 percent), and secondary cracks are easy to form. The tests prove that the fluidity of the slurry is good when the fluidity of the slurry is between 200mm and 240mm after the oyster ash and the silt are uniformly mixed by adding water according to the mass ratio of 1 (3-15). The initial setting time of the grout is about 100 minutes, so that the sufficient time is increased for grouting operation, and the final setting time is 11.2-16.4 hours, so that the grout can exert strength in a short time, and mechanical support and reinforcement effect are provided. Compared with other mural repair slurries, the slurry solidified body provided by the invention has smaller shrinkage, has larger porosity, better environmental resistance and better aging resistance, and can completely meet the reinforcement requirements of hollowing, cracking and anchoring of murals.
The technical scheme in the embodiment of the application at least has the following technical effects and advantages:
the slurry of the invention solves the problems of strength, durability, fracture resistance and pressure resistance of the mural after hollowing, cracking and anchoring repair and reinforcement, and provides a novel material for repairing the damaged mural cultural relics. The slurry has wide raw material sources and simple formula, and can be directly used for grouting after all the components are mixed according to the corresponding proportion, so that the slurry is convenient to use; the initial setting time is long, enough time can be provided for grouting operation, the fault tolerance is high, the final setting time is short, the strength of grout is guaranteed to be exerted in a short time, mechanical support is provided, and the reinforcing effect is guaranteed. The slurry prepared by the preparation method has good fluidity, the slurry solidified body has larger porosity, smaller contractibility and better ageing resistance, the reinforcement requirements of hollowing, cracking and anchoring of the mural are completely met, and the repair effect of the mural is obvious.
