It the principle of the present invention and has the beneficial effect that
1, it in the present invention, in order to increase stability of the hydrated product in gelling system, is introduced in modified material siliceous
Material component.In the process for preparation of magnesium oxychloride material, MgO is usually excessive.The appropriate dosage for increasing MgO, not only can be with
The pH value of slurry is improved, and to reaction rate is improved, guarantees MgCl2Abundant reaction it is advantageous, but excessive magnesia is in body
It will affect the volume stability of MOC in system, while will also result in scum.Active siliceous material rice hull ash, height are introduced in system
Ridge soil property spoil fluidized bed lime-ash, inside active siliceous material contained by active SiO2It is anti-aquation to occur with excessive magnesia
It answers, forms indissoluble salt MgSiO3:
3MgO+4Si02+8H20→3MgO·4SiO2·H2O
Amorphous Si O in low-temperature rice husk ash (L-RHA)2Content is all nano level active SiO up to 90% or more2Gel
Particle, the huge (50~100m of specific surface area2/ g), so low-temperature rice husk ash has very high pozzolanic activity.Nanometer in L-RHA
The active SiO of grade2Particle can not only eliminate the influence of extra magnesia, and Si is also solid-solution in 5-1-8 crystalline phase hole, together
When also change 5-1-8 crystalline phase and Mg (OH)2Match, more tend to the structure matching of reaction product rationally, micro- knot
Structure is finer and close, and time more long this effect is more obvious.
Kaolinite soil property spoil fluidized bed lime-ash is widely present in the near coal-mine power station in various regions.Kaolinite soil property gangue is widely present
It the use of fluidized bed combustion is the effective technique for handling low calorie fuels in northern China coal bases.The coal of power plant emission
Spoil CFB ash slag not only substantial amounts, cheap, and be usually to be forged by salic minerals in middle warm area (600-900 DEG C)
Burn generation, potential pozzolanic activity with higher.
Although activity SiO in siliceous material2It can react at normal temperature with MgO, but its reaction speed is slower.In order to
Accelerate its reaction, introduces hexametaphosphate (SHMP).Catalyst energy and Ca2+、Mg2+Complex is formed, chemical reaction energy is reduced
It builds, makes to chemically react required activation energy reduction, remarkably promote Mg (OH)2Dissolution, make the Mg in solution2+And OH-Concentration is simultaneously
It improves, so that free [SiO3]2-Concentration increases.Since the concentration of reactant increases, so that alkali-activated carbonatite reaction accelerates, have
Conducive to raising MgO-SiO2–H 2The reaction speed of O system improves the formation speed of M-S-H.
2, magnesium oxychloride cement is porous polycrystal packed structures.The decline of its matrix strength, volume stability unstability,
Basic reason is that internal crystal structure occurs hydrolysis and destroys, and causes the skeleton of threadiness to be dissolved, with hydrolysate
It dissolves out, the space occupied originally by crystal structure in matrix is transformed into loose hole configurations.Skeleton structure is destroyed, and is caused strong
Degree decline also occurs apparent volume and shrinks under ambient pressure effect.
Whisker not only has needle bar shape structure similar with slurry matrix skeleton, but also its granule size has reached micron
Grade, may be implemented filling effect largely, therefore the filler can be formed and reaction product crystal phase phase in the base
As three-dimensional network skeleton structure；The chemical stability of whisker makes it still be able to play after 518 crystal phases decompose destruction
Skeleton function, to improve the stability of microstructure.Whisker belongs to inorganic salts, according to similar compatibility theory, with MOC matrix
It with preferable physical chemistry " caking property ", can preferably inhibit the generation of micro-crack on a microscopic scale, improve base structure
Density and stability.
3, in the present invention, the content of M- blending agents control Chlorine in Solution ion is utilized.M- blending agents is that a kind of water solubility has
Machine compound, it can form complex compound with small anion with that can wrap the ring shaped molecule structure for connecing anion.Chlorine oxygen magnesium glue
The solidifying easy damp suction surface halide accumulation of system, it is largely related with the chloride ion in solution.Chloride ion due to its electron rich structure easily and H2O
Forming quasi- hydrogen bond and affinity, a large amount of moisture, which enters in gelling system, in air has broken fluid balance, and crystal is hydrolyzed,
Magnesium chloride dissolves out, causes to return halogen phenomenon.Since M- blending agents volume is few and the speed of organic complex reaction is slower, adjust
Agent will not to the crystal hardened of early stage react have an impact, and to the chloride ion after matrix hardening in solid interior solution have compared with
Good fixed function.
4, due to magnesium oxychloride cement microstructure have porosity, internal pore structure be conducive to outside moisture into
Enter, destroys the chemical balance in internal liquid, cause the hydrolysis of crystal phase, while also the dissolution for hydrolysate magnesium chloride provides
Channel, forms a kind of vicious circle, leads to structural damage.Therefore the present invention from different angles, carries out porous matrix
Improve, improves the compactness of matrix.On physical layer, mainly start with from introducing organic matter.Redispersible rubber powder can be uniform
Be dispersed in cementitious material, meeting water will become lotion, and lotion enters in pore structure, can play certain closure and make
With；Secondly lotion can block contact of the crystal structure with water in the membrane structure that inside is formed, and prevent its aquation from decomposing.
