Abstract
The invention relates to a high-durability geopolymer concrete foundation. The high-durability geopolymer concrete foundation comprises, by weight, 200-277 parts of fly ash, 55-92 parts of smelt slag, 35-70 parts of ultrafine powder, 570-600 parts of fine aggregate, 1100-1180 parts of coarse aggregate, 30-40 parts of water glass and 150-200 parts of water. The high-durability geopolymer concrete foundation has the advantages that the high-durability geopolymer concrete foundation does not need to be compounded and used with water reducing agents, and geopolymer gelation materials which are mixtures are constructed from the fly ash, the smelt slag and the water glass and have high-durability characteristics of erosion resistance and high and low temperature resistance owing to characteristics of geopolymers; coordination and auxiliary adjustment effects can be realized by the ultrafine powder for the water retention, the wrapping property and the cohesiveness of the geopolymer concrete mixtures, and certain self-curing effects further can be realized by porous structures of the ultrafine powder; improvement effects can be realized by the smelt slag for the compactness and the mechanical strength of hardened concrete.
Description
Technical field
The present invention relates to building material technical field, especially a kind of high-durability geopolymer concrete foundation.
Background technology
In the world is started to the research of geopolymer the eighties in last century.Generally with metakaolin as primary raw material,
By the effect of alkali-activator, about 100 DEG C obtained by synthesis.If replacing metakaolin with flyash, aggregate velocity is limited,
Intensity is relatively low.Trace it to its cause, be characterized in particular in how guaranteeing the high activity of Si-Al materials, it is ensured that powder body can dissolve rapidly
There is reconstruct, tissue in alkaline solution in Si, Al monomer that can move freely, the monomer being dissolved down, be built into it is a kind of by
AlO4And SiO4The cancellated inorganic polymer aluminum silicate cross-linking type hydrated product of tetrahedral structural unit composition 3 D stereo,
Condense hardening.
Basement process generally refers to the bearing capacity for improving the ground (soil or rock) of supporting building, improves its change
The project slash that shape performance or impermeability are taken.Concrete belongs to fragile material, for a long time under load action, easily
Generation cracking destruction.Geopolymer is in itself oxide network structural system, do not aoxidize between l000～1200 DEG C, regardless of
Solution；On the other hand, it is not oxidized that closely knit oxide network system can completely cut off air, protection inner material.
The content of the invention
The invention solves the problems that the shortcoming of above-mentioned prior art, there is provided a kind of without the need for water reducer compound use, with good
The high-durability geopolymer concrete foundation of water-retaining property, encapsulation, cohesiveness and mechanical strength.
The present invention solves the technical scheme that its technical problem is adopted：This high-durability geopolymer concrete foundation, it
It is made up of the raw material of following portions by weight:200～277 parts of flyash, 55～92 parts of smelted furnace cinder, micropowders 35～70
Part, 570～600 parts of fine aggregate, 1100～1180 parts of coarse aggregate, 30～40 parts of waterglass, 150～200 parts of water.
The flyash is high-calcium fly ass, preferably one-level flyash.
The smelted furnace cinder is the Industry Waste that slag, carbide slag, alkaline residue, phosphorus slag, chromium slag, boron slag etc. possess thermal history process
Slag, preferably up to《The ground granulated blast furnace slag that GBT 18046-2008 are used in cement and concrete》The smelting of S75 standards
Slag.
The fine aggregate is to meet national standard《Building sand》The fine aggregate of (GB/T 14684-2011), preferably carefully
Fluvial sand of the degree modulus 2.2～2.5.
The coarse aggregate is to meet national standard《Cobble for building, rubble》(GB/T14685-2011) particle diameter is more than
The compositionss of the aggregate that the aggregate of 5mm, preferably 5～20mm, 20～40mm, two kinds of levels are matched somebody with somebody.
Described waterglass is the waterglass powder body that modulus is 2.30-2.50.
The micropowders are one or two mixture in triple superphosphate, fine particle calcium carbonate, zeolite powder, cenosphere, silicon ash, preferably
For powder of the unit weight less than 2.0g/cm3, i.e. one or two mixture of zeolite powder, cenosphere.
Invention has the advantages that：The present invention is without the need for water reducer compound use, flyash, smelted furnace cinder, waterglass structure
Build geopolymer gelled material, geopolymer its own feature give this mixture resistant to corrosion, high-low temperature resistant high-durability it is special
Point；Over the ground the water-retaining property of polymer concrete mixture, encapsulation, cohesiveness have coordination auxiliary Accommodation to micropowders, surpass
The porous structure of trickle powder also has certain Self-curing effect；Smelted furnace cinder is strong to the density of concrete, mechanics after hardening
Degree there is also amplification effect.
