Abstract

The invention discloses a lightweight high strength material for tunnel and underground pipeline construction and a preparation method of the lightweight high strength material. The lightweight high strength material for the tunnel or underground pipeline construction comprises the following components: 10 to 25 parts of cement, 20 to 60 parts of sand, 1 to 5 parts of slaked lime, 5 to 25 parts of mineral slag, 5 to 15 parts of pulverized fuel ash, 20 to 35 parts of water, 0.1 to 0.8 part of sodium sulfate, 0.1 to 0.3 part of protein foaming agent and 0.5 to 1.5 parts of preservative. The lightweight high strength material has the advantages of light weight and high strength, simpleness in preparation, energy saving, environmental friendliness, simpleness and convenience in operation and the like, meanwhile has excellent corrosion resistance and can be applied to various severe environments.

Description

technical field [0001] The invention belongs to the field of green and environment-friendly building materials, in particular to a lightweight high-strength material used in tunnel or underground pipeline construction and a preparation method thereof. Background technique [0002] In the current engineering construction, tunnels or underground pipelines mainly use prestressed concrete components, and the amount of concrete is large, and the workload of transportation and construction is heavy. At present, some projects use steel-concrete structures to solve this problem, but the cost of steel-concrete structures is very high. Contents of the invention [0003] Purpose of the invention: to provide a light-weight high-strength material for tunnel or underground pipeline construction to solve the above-mentioned problems in the prior art. A further object is to provide a method for preparing the above-mentioned lightweight and high-strength material for tunnel or underground...
