Abstract

The invention provides a seepage-proofing leaking-stopping material and a preparation method thereof. The seepage-proofing leaking-stopping material comprises leaf fibers, gypsum, an expanding agent, cement and water. The leaf fibers are added to the cement, so that the tensile strength of cement mortar is improved. Meanwhile, the cost of the seepage-proofing leaking-stopping material can be greatly reduced through the leaf fibers, and the seepage-proofing leaking-stopping material can be widely applied to the fields of tunnels and underground structures, mine excavation and water conservancy and hydropower foundation reinforcement projects and the like.

Description

technical field [0001] The invention relates to building materials, more specifically, to an anti-seepage and plugging material and a preparation method thereof. Background technique [0002] Houses, tunnels, dams, and underground pipelines will all be cracked or damaged, so dams or underground pipelines will leak or seep. To deal with the above situations, plugging and grouting materials are usually used to block the damaged places. In order to avoid damage to dams or underground pipelines caused by long-term water leakage or seepage. [0003] Plugging grouting materials can be divided into cement grouting materials (granular grouting materials based on cement) and chemical grouting materials according to the state of the grout. Among them, cement grouting materials have high stone body strength, low price, convenient transportation and storage and The grouting process has the advantages of simple, etc., but at the same time, it also has the disadvantages of long setting t...
