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
The present invention relates to a kind of New Building Materials of port engineering utilization of waste material, particularly a kind of material of construction that utilizes bottom silt; The invention still further relates to a kind of preparation method of above-mentioned material of construction.
Background technology
The port engineering construction needs a large amount of sand material resources, and with environment protection, sand material resource day is becoming tight, and has seriously restricted port construction speed and quality.Port construction need to be excavated a large amount of mud, is that mud is poured on the off-lying sea in the past, causes waste and pollutes.Thin due to sludge granules, water content is high, mechanics index of physics is poor, in port construction, must process mud, mud is excavated, and land reclamation, uses as ground after adopting discharging consolidation.The discharging consolidation of mud vacuum preloading commonly used and piling prepressing technology and technique, but all need a large amount of backfilling materials, comprise working cushion layer, sand bedding course, protective layer and ballast layer, all need a great amount of building material, particularly sand material.But the sand material resource is at full stretch.Therefore we seek new equivalent material and seem and be even more important.
Mine tailing sand is the waste after various ore extracting effective componentss, and pile up like a mountain throughout the year, takies a large amount of soils, and surrounding environment is caused very large pollution, up to the present, still there is no perfect processing, utilizes way.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposed the preparation of a kind of prescription rationally, result of use is good and can effectively utilize the material of construction that utilizes bottom silt of rejected material.
Another technical problem to be solved by this invention has been to provide the above-mentioned preparation method who utilizes the material of construction of bottom silt.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of material of construction that utilizes bottom silt, be characterized in: this material is made by CHARACTERISTICS OF TAILINGS SAND, mud and solidifying agent mix and blend, the mass water content of described mud is 60～100%, and mud, CHARACTERISTICS OF TAILINGS SAND and weight of cement are than being l:1～3:0.04～0.12.
In above-described building material technology scheme: described mud, CHARACTERISTICS OF TAILINGS SAND and weight of cement ratio are preferably l:3:0.05.
Technical problem to be solved by this invention can also further realize by following technical scheme.The present invention is a kind of material of construction that utilizes bottom silt, be characterized in: this material is made by CHARACTERISTICS OF TAILINGS SAND, mud, cement and stone mix and blend, the mass water content of described mud is 60～100%, and the weight ratio of mud, CHARACTERISTICS OF TAILINGS SAND, cement and stone is 1:2～3:0.04～0.12:3～5.
In above-described material of construction: the weight ratio of described mud, CHARACTERISTICS OF TAILINGS SAND, cement and stone is preferably 1:3:0.12:4.
Technical problem to be solved by this invention can also further realize by following technical scheme.The present invention also provides a kind of preparation method who utilizes the material of construction of bottom silt as described in above technical scheme, is characterized in, its step is as follows:
(1) crawl mud store up to its water content be 60～100%;
(2) add CHARACTERISTICS OF TAILINGS SAND and cement by described weight proportion in mud, perhaps add again stone, stir, and get final product.
In the preparation method of the above-described material of construction that utilizes bottom silt: after stirring, mixture can be transported to the place to use, pave, roll, get final product; Can also make according to a conventional method prefabricated section uses.
CHARACTERISTICS OF TAILINGS SAND of the present invention can be the waste after various ore extracting effective componentss, is generally particulate state.
Compared with prior art, advantage of the present invention and technique effect are as follows:
1, the present invention can realize the utilization of waste material of mine tailing sand: the port construction fast development, the technology of the present invention can use mine tailing husky in a large number, not only solve the problem of outlet of mine tailing sand, solved environmental issue, also saved the natural resource of a large amount of sand material material of construction.Material of the present invention can be applied in the engineerings such as the working cushion layer, concrete material, land-based area backfill of cement stabilizing layer, vacuum preloading under the road stockyard.
2, the present invention can realize the utilization of waste material of mud: in port construction, need to excavate a large amount of mud.The present invention can use mud in a large number, has solved the problem of outlet of mud, and also having accomplished turns waste into wealth.
3, the intensity of material of the present invention is high, and its intensity can reach 6MPa, far above the mechanics index of physics of general concrete.A small amount of pollutent in mine tailing sand is fixed by mud, has reached environmental requirement.The pollutant emission of not finding to exceed standard enters the sea.
4, material cost of the present invention is low, and mud is also refuse, uses these materials, can greatly reduce construction costs.
5, material of the present invention can be realized the rapidly solidified of mud, and mud is realized rapidly solidified, and mud has become the gelling material of mine tailing sand, has improved the intensity of compaction material.
6, a large amount of natural resource have been saved in the application of material of the present invention.
