Building material utilizing seabed sludge and preparation method of building material

Abstract

The invention discloses a building material utilizing seabed sludge. The building material is formed by mixing and stirring tailing sand, sludge and a curing agent, wherein the moisture content of the sludge is 60%-100%; the weight ratio of the sludge to the tailing sand to the cement is 1:(1-3):(0.04-0.12). Stones are further added in the building material disclosed by the invention. The invention further discloses a preparation method of the building material. According to the building material utilizing seedbed sludge and the preparation method of the building material disclosed by the invention, the tailing sand can be recycled, the outlet problem of the tailing sand is solved, the environment-friendly problem is saved, the natural resources of sand-stone building materials are saved, the strength is as high as 6MPa and the manufacturing cost is low. The building material disclosed by the invention can be applied to the projects including a cement stabilization layer below a road storage yard, a vacuum preloading working cushion layer, concrete materials, land backfilling and the like.

Description

Technical field [0001] The invention involves a new type of building materials used in port engineering waste, especially a building material that uses the muddy underwater silt; the present invention also involves a preparation method of the above -mentioned building materials. Background technique [0002] The construction of port projects requires a lot of sand and gravel resources. With environmental protection, sand and gravel resources are becoming more tense, which seriously restricts the speed and quality of port construction.The construction of the port requires a large amount of silt, which used to pour the mud to the outer sea, causing waste and pollution.Due to the fineness of the mud, high water content, and poor physical mechanical indicators, the mud must be treated in the construction of the port, the silt must be removed, and the land must be used to use the land.The mud's drainage solids are commonly used vacuum pre -pressure and stacking pre -pressure technolog...

Problems solved by technology

[0003] Tailings sand is the waste after extracting active components from various ores. It piles up like mountains all the year round, occupies a lot of land, and causes great pollution to the surrounding environment. So far, there is no perfect treatment and utilization method.
