Problems solved by technology

[0003] At present, the in-situ restoration of travertine geology has been realized. For example, Chinese patents 201611032119.2 and 201611031004.1 both disclose repairing agents for travertine geological restoration. The repairing agent can be used to repair the gaps in the travertine damaged side dam in situ, but the It takes more than 6 days to complete the restoration with the traditional method, which cannot meet the demand for rapid restoration of travertine geology

preparation example Construction

[0025] The invention provides a method for preparing a piece for travertine geological restoration, comprising the following steps:

[0026] (1) Mixing and aging waste travertine granules, calcium-based additives and water in sequence to obtain a pouring material;

[0027] (2) pouring and molding the pouring material obtained in the step (1) to obtain a molding;

[0028] (3) Carrying out gas-thermal curing to the molded blank obtained in the step (2) to obtain a workpiece for travertine geological restoration; the gas used for the gas-thermal curing is carbon dioxide.

[0029] In the invention, waste travertine granules, calcium-based additives and water are sequentially mixed and aged to obtain pouring materials. In the present invention, the particle size of the waste travertine granular material is preferably 0.1-2 mm, more preferably 0.2-1.5 mm, more preferably 0.5-1.0 mm.

[0030] In the present invention, the waste travertine granular material is preferably obtained by...

Embodiment 1

[0069] Remove impurities, grind and sieve the waste travertine to obtain waste calcified granules with a particle size of 1 mm; sieve calcium hydroxide to obtain a calcium-based additive with a particle size of 100 mesh; mix 40 parts of waste calcified granules with 60 1 part of calcium hydroxide is put into the mixer, first dry stir for 10min and mix evenly, then add water according to the solid-to-liquid ratio of 80:20, wet stir for 20min, and after aging for 24h, the pouring material is obtained;

[0070] Apply engine oil to the inner wall of the mould, pour the pouring material into the mould, hold the pressure at 15MPa for 1 hour, and then release the mold to obtain a molded body;

[0071] Carry out gas heat curing under the following conditions. The curing conditions are temperature of 150°C and supply concentration of carbon dioxide of 20m 3 / h, curing for 24h, and the parts for travertine geological restoration are obtained after natural cooling.

[0072] The obtained...

Abstract

The invention belongs to the technical field of travertine repair, and particularly relates to a workpiece for travertine geological repair and a preparation method and application thereof. The methodis characterized in that waste travertine particles serve as raw materials and are subjected to pneumatic thermal maintenance in the carbon dioxide atmosphere by adding a calcium-based additive, andthus strength repair of the waste travertine is accelerated. The embodiment result proves that the preparation method only needs to conduct pneumatic thermal maintenance for 20-24 hours, and the workpiece for travertine geological repair with the pressure being higher than or equal to 16MPa can be obtained, and the obtained workpiece can be directly applied to calcified geological repair.

Description

technical field [0001] The invention belongs to the technical field of travertine restoration, and in particular relates to a piece for travertine geological restoration and its preparation method and application. Background technique [0002] Travertine landscape or travertine geology not only has high ornamental value, but also has great humanistic value and scientific research value. However, travertine geology is easily damaged, such as climate change, water erosion, earthquakes and other external unfavorable conditions will cause damage to travertine geology. Once the travertine geology is damaged, it is difficult to recover naturally, and artificial intervention is required to repair the damaged travertine geology. [0003] At present, the in-situ repair of travertine geology has been realized. For example, Chinese patents 201611032119.2 and 201611031004.1 both disclose repairing agents for travertine geological restoration. The repairing agent can be used to repair t...
