Description
Technical field
The present invention relates to the preparation method of a kind of moistureproof Salt And Alkali Tolerance building mortar, belong to construction material preparing technical field.
Background technology
Building mortar is to be bonded as overall mortar by building block materials (brick, stone, building block) by laying bricks or stones.It is by inorganic gel material
Material, fine aggregate and water, the most also mix some admixture composition, often using comprcssive strength as topmost technical performance index.
Building mortar is usually used in building masonry (such as brick, stone, building block) structure, smearing of building surfaces externally and internally (such as metope, ground, ceiling) by laying bricks or stones
Face, large wall panel, the jointing of masonry walls, and the bonding etc. of ornament materials.
The building in the area that the coastal region in east China is high with other saline and alkalines is owing to being chronically under high salinity environment easily quilt
Corrosion, traditional moistureproof building mortar material salinity and alkalinity resistance is poor so that it is service life significantly shortens, it is easy to be destroyed thus
Lose moisture effect, add that common buildings barrier material is changed highly difficult, therefore in high salinity regional architecture to moistureproof mortar
Saline and alkaline requirement is higher.
Trehalose has the protective effect of mystery to organism, is because trehalose and at high temperature, high and cold, hyperosmosis and does
The protecting film of uniqueness, protected protein matter molecule invariance effectively can be formed at cell surface under the severe environmental conditions such as dry dehydration
Inactivation, thus the life process of the body that sustains life and biological characteristic, many adverse circumstances to external world show outstanding degeneration-resistant tolerance
, all internal substantial amounts of trehalose there is and has direct relation in the species of power with them.Two water crystallization trehaloses are at relative humidity 92%
Following no hygroscopicity, and anhydrous trehalose has hygroscopicity at relative humidity more than 30%, this character makes it both have low moisture absorption
Property, there is again humectant function.
Summary of the invention
The technical problem to be solved: poor for the most traditional moistureproof building mortar material salinity and alkalinity resistance,
Making significantly shorten its service life, it is easy to be destroyed thus lose the problem of moisture effect, the present invention is with river sand as raw material, first
Soak through the methane liquid rich in microorganism and use liquid nitrogen flash-frozen, utilizing the effect of splitting of microorganism and ice composite modified, expand river
Husky aperture, inside also increases avtive spot therein, then carry out twice-modified with Salt And Alkali Tolerance algae and Oleum Ricini to river sand, profit
With in Salt And Alkali Tolerance Sargassum body rich in trehalose under high salinity environment, form the protecting film of uniqueness on river sand surface, buffer saline and alkaline
Impulsive force, the river sand surface that acts on of recycling microorganism increases hydrophobicity ester group, increases its moisture resistance, last and cement
And other adjuvants are compounding prepared, the moistureproof building mortar moisture resistance that the present invention prepares is good, and has splendid Salt And Alkali Tolerance performance,
Prospect of the application is wide.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) fishing for 10~20kg river sands and cross 20 mesh sieves, the river sand bundle after sieving wraps and tightens gauze with rope yarn
Ensure that river sand will not spill, then the river sand wrapped by bundle immerses in fowl and animal excrement ferment biomass pool, after standing dipping 3~5h
Take out;
(2) opening gauze, tiling river sand also uses liquid nitrogen at river sand surface spraying 40~60s immediately, makes immersion river sand capillary porosity
In the instantaneous icing of methane liquid, then the river sand after liquid nitrogen spraying is put into baking oven, after drying 20~30min at 105~110 DEG C
Take out, more repeatedly process 3~5 times by identical dipping, liquid nitrogen spraying and baking step, finally give pre-modified fine aggregate, standby
With;
(3) weigh 8~10kg dulses, 10~12kg Sargassum fusiforme (Harv.) Setch and 15~18kg Sargassums put into powder in tissue pulverizer
Broken 20~30min obtain mixing Sargassum slurry, and mixing Sargassum slurry is moved into reactor, in temperature be 25~30 DEG C, air the wettest
Degree is the most mouldy process 7~10 days under conditions of 70~80%, after mouldy end, filters and removes filtering residue, obtain filtrate;
(4) for 5:1 filtrate obtained above and Oleum Ricini mix homogeneously are prepared composite modified liquid by volume, more in mass ratio
For 2:3, composite modified liquid is sent forth on standby pre-modified fine aggregate as fermentation substrate uniformly by watering can, is moved
Enter pottery fermentation tank, then by inoculum concentration be 10% in fermentation substrate access bacillus pyocyaneus, hermetically sealed can mouth is incubated at 30~40 DEG C
Modified 15~20 days of fermentation;
(5) isolated modification fine aggregate, natural wind after repeatedly rinsing 15~20min with deionized water are filtered after fermentation ends
Dry, obtain moistureproof anti-saline and alkaline fine aggregate;
(6) by weight meter weigh 40~60 parts of above-mentioned protection against the tide resist saline and alkaline fine aggregate, 30~40 parts of portland cements, 5~8 parts
The butyl rubber powder of 100 mesh, is sequentially added in batch mixer mixing 40~60min, and discharging obtains mortar slurry, then is in mass ratio
Deionized water and mortar slurry are moved into after mixing 1~2h with 100~150r/min rotating speed stirrings in mortar mixer by 3:4 successively
Discharging, obtains moistureproof Salt And Alkali Tolerance building mortar.
The application process of the present invention: first the materials such as the dust of ground matrix surface, loose matter, oil stain are cleaned out,
Again matrix surface is watered drenched, then use the slurry that the moistureproof Salt And Alkali Tolerance building mortar of above-mentioned preparation and water reconcile into
Wiping one's face, controlling thickness is 7~8mm, then carries out being compacted, after floating and surface press polish so that it is after natural air drying final set, Ying Jin
Row watering maintenance, curing time is 7~10 days.After testing, its intensity reaches more than 20.5MPa, and water retention reaches 90%
Above, and its Saline alkali tolerance is good, and the infiltration capacity of chloride ion is less than 4.0 × 10-3mg/cm2D, water demand ratio is less than 55%.
The present invention is compared with additive method, and Advantageous Effects is:
