Joint sealing agent for travertine geology and application thereof

Abstract

The invention provides a joint sealing agent for travertine geology. The joint sealing agent is prepared from the following components in parts by weight: 60-90 parts of a travertine base material, 5-25 parts of a crosslinking agent and 1-9 parts of a strengthening agent. According to the joint sealing agent, the adopted travertine base material is good in compatibility with a repaired geological environment, so that in-situ repair of the travertine geology without damage and pollution is realized, and the repair efficiency and the strength after repairing are high; and meanwhile, with waste travertine as the base material, resource utilization of the waste travertine is realized in the premise of ensuring the environmental friendliness of the material. The provided joint sealing agent for the travertine geology can be used for treating joints of a stone dam at the edge of a ground surface colored pool in a travertine scenic spot and is strong in pertinence. Shown by results of the embodiment of the invention, in the using process of the joint sealing agent for the permeable travertine geology, the initial setting time is shorter than 30h, the final setting time is shorter than 40h, the strength can reach 1-3MPa after the joint sealing agent is used for 7 days, and the strength can be higher than 5MPa after the joint sealing agent is used for 28 days.

Description

technical field [0001] The invention relates to the technical field of geological restoration, in particular to a seam filling agent for travertine geology and its application. Background technique [0002] Travertine is a bicarbonate-rich surface water that, under suitable physical, chemical or biological conditions, is close to and / or exposed to the surface of the earth, forming a carbonate travertine deposit due to the escape of carbon dioxide in large quantities. These sediments change with the movement of the water flow and the change of the water circulation system, forming travertine landscapes, such as travertine side stone dam colored pools, travertine beach flows, travertine waterfalls and travertine collapse caves. As a special type of karst landform, while being continuously formed, it also faces the phenomenon of landscape evolution and degradation under the influence of normal erosion. The most obvious ones are travertine side stone dams and more obvious cracks...

Problems solved by technology

[0003] For repairing materials for cracks or fissures such as travertine alexandrite dams, it is necessary to focus on maintaining the original geological characteristics of travertine, but conventional crack repairing materials such as caulking agents and cement have poor ecological compatibility with travertine geology. It is difficult to ensure that the material used for crack repair is consistent with the color, density and permeability coefficient of the travertine, resulting in the destruction of the original characteristics of the travertine

For example, Chinese patent CN102173661A discloses a self-leveling polymer cement-based repair mortar for repairing cracks in concrete buildings, which can be used for repairing cracks in travertine geology, but the use of a large amount of cement and sand will cause calcium Chinese geology causes permanent damage; Another example is that Chinese patent CN102604463A discloses a water-based crack repair glue used for wall crack repair and surface reinforcement, which can effectively resist the generation of wall cracks and tortoise cracks, but uses a large amount of elastic emulsion, Antifreeze, poor ecological compatibility
