Grouting agent for reinforcing glutenite fissures and application thereof

Abstract

The invention relates to a method for reinforcing glutenite fissures, and discloses a grouting agent for reinforcing glutenite fissures. Common Portland cement has large particles, thereby easily blocking pores or forming bridge chains around the pores so as to prevent other particles from entering; when the glutenite fissures are filled, an obvious dividing line exists between the grouting agentand the glutenite, so that the grouting agent is easy to separate from the fissure to undermine the glutenite fissure reinforcing effect. The grouting agent comprises the following substances by weight percent: 52-65%wt of sodium silicate, 23-32%wt of coal ash, 5-12%wt of sodium fluorosilicate, 2-5%wt of brucite powder and 1-5%wt of regulator. The grouting agent can well fill the glutenite fissures and is hard to separate from the glutenite, thereby better reinforcing the glutenite fissure. The invention further provides application of the grouting agent for reinforcing the glutenite fissures.The grouting agent can better fill the glutenite fissures and achieves a goal of better reinforcing the glutenite fissures.

Description

technical field [0001] The invention relates to a method for strengthening glutenite fissures, more specifically, it relates to a grouting material for strengthening glutenite fissures and its application. Background technique [0002] As one of the important elements of garden landscaping, landscape stone plays an irreplaceable role in the garden. Glutenite is rounded in shape, hard in texture, and its surface is weathered in a circular peeling shape. It is one of the stones commonly used as landscape stones. Glutenite is a kind of rock cemented by round gravel. It is a clastic rock in which round and subround gravels account for more than 30% of the total rock. The filling is sand, silt, clay and chemical precipitation. substance. In the process of natural weathering, cracks are easy to exist on the glutenite, and the existence of cracks reduces the structural strength of the glutenite and is easy to crack.

[0005] However, the filling pores of glutenite are very small, and the pore diameter is about 20-60 μm. If the pores are to be filled, the particle size of the filler particles should be less than one-third of the pore diameter. Block the pores or form a bridge chain around the pores to hinder the entry of other particles. When filling the conglomerate fissures, there is a clear boundary between the grouting material and the glutenite.
