Description
Technical field
The invention provides a kind of ground surface material of seawater corrosion resistance, belong to building material technical field.
Background technology
Along with Global climate change, sea-level rise has become the event that the maritime nation pays close attention to.In addition, because unusual storm and precipitation that climate change causes also can increase the generation that the road surface, coastland suffers marine denudation.The buildings such as many sea port docks, oil drilling platform are because phenomenons such as significantly degrading only just appearred in the corrosion of seawater in several years, crackings.
At present, mainly be in material, to add corrosion resistant additive to finish for the method that improves the ground surface material anti-seawater corrosion.But this method need to consume too much chemical agent, and additive also can be aging gradually in seawater.
Summary of the invention
For above problem, the invention provides a kind of ground surface material of seawater corrosion resistance.
The technical scheme that adopts is:
A kind of ground surface material of seawater corrosion resistance, the composition that comprises following weight percent meter: semi-hydrated gypsum 20～30%, cement 40～50%, quartz sand 5～10%, alumina-ceramic powder 5～10%, carbon fiber 1～3%, potassium titanate crystal whisker 1～3%, titanium dioxide 5～10%, flyash 5～10%, mould inhibitor 1～3%.
The preparation method is:
(a) take by weighing gypsum, cement, quartz sand, carry out pre-dispersed.
(b) more above-mentioned gypsum, cement, quartz sand are mixed.
(c) take by weighing alumina-ceramic powder, carbon fiber, potassium titanate crystal whisker, titanium dioxide, flyash, mix.
(d) mixture and the mould inhibitor with step (b) and step (c) gained mixes, and gets finished product.
More preferably, above-mentioned alumina-ceramic powder is that particle size range is 0.2 μ m ~ 1 μ m.
Preferred, above-mentioned titanium dioxide particle size range is 0.15 ~ 0.3 μ m.
The preferred scheme of the present invention is to comprise following component by weight percentage: semi-hydrated gypsum 21%, cement 45%, quartz sand 6%, alumina-ceramic powder 5%, carbon fiber 1%, potassium titanate crystal whisker 1%, titanium dioxide 10%, flyash 10%, mould inhibitor 1%.Make the road surface that makes have the performance of better intensity and seawater corrosion resistance.
Owing to include median size different alumina-ceramic powder, titanium dioxide in the ground surface material of seawater corrosion resistance provided by the invention, they can take in the road surface that lays in mutual embedding, have improved the road surface degree of compactness, prevent that seawater from permeating in the road surface.In addition, because the chemical stability of alumina-ceramic powder and titanium dioxide is good, further strengthened the anti-sea-water corrosion performance on road surface.And, owing in ground surface material, include carbon fiber and potassium titanate crystal whisker, can the shape reticulated structure in the road surface, between granular powder, more firmly be combined, further strengthen degree of compactness and the anti-sea-water corrosion performance on road surface.
Above-mentioned mould inhibitor can adopt the mould inhibitors commonly used such as common zinc sulfate, zinc oxide, borax, pentachlorophenol.
This material adopts less organic chemistry medicament, and seawater corrosion resistance can be strong, and each component easily obtains, and the pavement construction that is suitable for the coastland uses.
