Normal temperature consolidation materials for construction

Abstract

The provided new building material consolidated at normal temperature is prepared mainly by castoff of building and mine or power plant, controllable on consolidation time and strength, has well physical performance with permeability coefficient less than 5e-7cm / s and compression strength up to 7MPa or 22Mpa as building block, reduces unit cost more than 45%.

Description

technical field [0001] The invention relates to a normal-temperature consolidation material used for grouting reinforcement and anti-seepage of engineering foundations and geotechnical structures, underground filling of mines and production of building filling blocks. It is a building material. Background technique [0002] Industrial and civil construction projects, mine construction projects, dam reinforcement projects, traffic tunnel projects, urban subway projects, underground geotechnical projects, etc., mostly need to use grouting construction methods for reinforcement treatment or seepage prevention and water blocking to ensure project quality and safety operate. At present, the cement grout and clay grout used at home and abroad still have the shortcomings of difficult control and adjustment of initial setting time and final setting time, low shock resistance and impermeability, poor hydrodynamic pressure resistance, and low resistance to groundwater acid and alkali...

AI Technical Summary

Problems solved by technology

At present, the cement grout and clay grout used at home and abroad still have the shortcomings of difficult control and adjustment of initial setting time and final setting time, low shock resistance and impermeability, poor hydrodynamic pressure resistance, and low resistance to groundwater acid and alkali ion erosion. There are still problems to be solved in engineering quality and reliability

Due to the high cost of cement slurry and the loss of soil resources caused by clay slurry, reinforcement and anti-seepage projects with a large amount of materials, especially underground filling projects for abandoned mines, are all disadvantages

Although tailings sand is used as the main material to fill abandoned mine shafts, the stone bodies formed by the prior art are soluble in water and have poor roofing (i.e. filling) and low compressive strength, so it has not been successful; so there has been no suitable method. , Reliable and cheap filling material

Most of the current building filling blocks need to be sintered, which requires a lot of energy such as coal, and there is environmental pollution

According to the international Internet search of dozens of website databases at home and abroad including the National Library of China, China Academic Journal Abstracts, China Science Citation Database, China Science and Technology Paper Statistics and Analysis Database, China Journal Network, European Website and the University of California, Berkeley Library As a result, there is no document report similar to the present invention at present both at home and abroad
