Abstract

The invention relates to a grouting material for reinforcing rock mass cracks of a stone cave temple and a preparation method and a use method of the grouting material. The grouting material for reinforcing the rock mass cracks of the stone cave temple comprises the following components in parts by weight: 30-50 parts of modified ginger nut; 7-12 parts of a mineral admixture; 0.01-0.05 part of a sacrificial agent; 0.1-0.3 part of a water reducing agent; 1-3 parts of a nano modifier; 0.03 -0.05 part of an air entraining agent; 20 -60 parts of sand; and 15-26 parts of water. The grouting material for reinforcing rock mass cracks of stone cave temples, prepared by the invention, has the characteristics of adjustable fluidity, controllable strength and good air permeability. The coupling effect of the air entraining agent, the sacrificial agent and the water reducing agent can reduce the adsorption of the fine powder to the additive, reduce the surface tension of the capillary pore solution and refine the pore structure, and meanwhile, uniformly distributed bubbles are introduced into the slurry, so that the fluidity and the strength of the material are adjustable and controllable, and the air permeability is remarkably improved.

Description

technical field [0001] The invention relates to a grouting material for reinforcing and grouting cracks in grotto temple rock mass with adjustable fluidity, controllable strength and good air permeability. Background technique [0002] With the vigorous advancement of my country's spiritual civilization construction, more and more attention has been paid to the protection and utilization of cultural heritage. As a precious cultural heritage that concentrates on the brilliant achievements of religious architecture, sculpture and mural art, the importance of its protection and utilization is self-evident. Grotto temples in my country have the characteristics of diverse shapes, complex geological environments, and most of them are exposed to the wild. Therefore, they are often subject to erosion and damage from natural and human factors, and then appear weathering, rock mass cracks, and damage. Among them, rock mass fissures are more difficult, which will intensify water seepa...
