Abstract

The present invention relates to building engineering leak preventing and stopping technology, and is especially leak preventing and stopping method and material. The method is to utilize kelp with natural foaming performance in stopping leakage of building engineering and building. The leak stopping material consists of kelp 30-70 wt%, flyash 5-20 wt%, gypsum powder 5-20 wt%, standard cement 5-20 wt% and other admixture 0-20 wt%. The present invention has the advantages of low cost, simple composition, no damage to soil layer and no pollution on underground water resource.

Description

Technical field: [0001] The invention relates to the technical field of anti-leakage and plugging in construction engineering, in particular to a method for anti-leakage and plugging and a plugging material based on the method. Background technique: [0002] The anti-leakage and plugging technology in construction engineering is very critical to the quality of construction and construction, and it is related to the service life of construction projects and buildings and the safety of people's lives. Especially with the large-scale increase of my country's infrastructure investment, it is very necessary to strengthen the anti-leakage and plugging process effects of construction projects and buildings in the construction of infrastructure and buildings in coastal and riverside cities. [0003] The following are several existing leak plugging materials: [0004] 1. Chinese Invention Patent Publication (CN1560171A), discloses a high-performance cement-based water-stopping and l...
