Description
Technical field:
The invention belongs to the material of construction class, be applicable to preparation high durability concrete pile tube.
Background technology:
From the mid-90 in last century, prestressed concrete pipe pile has obtained developing rapidly in China's Delta of the Pearl River, Yangtze River Delta.Progress along with modernized concrete technology, the concrete product state of the art that comprises pile tube is greatly improved, aspect the preparation of the production of tubular pile concrete, pile tube, utilisation technology, related production equipment, a series of original technology that have independent intellectual property right have been formed.National pile tube output was about 2.5 hundred million meters in 2006, compared with the eighties in last century, increased nearly a hundred times, and kind and specification constantly increase, and application market is also upcountry expanded from southeastern coast, becomes in the world to produce, use the maximum country of pile tube.
The concrete product endurance issues is one of subject matter of academia and engineering circle concern always, in second concrete durability international conference holding in 1991, in the reason of concrete material and component damage, the physics chemical action in the erosion environment comes the 3rd.China is economically developed, the density of population is big, urbanization process coastland rapidly, comprises that the soil of coastland, Liaoning, Tianjin, zhejiang and other places belongs to marine solonchak, and cement concrete product is had the deep-etching effect.The marine solonchak pH value usually about 7.5～8.5, SO in the soil
4 2-Content is up to 0.28% of soil weight, also contains strong corrosive mediums such as a large amount of carbonate and magnesium salts simultaneously.The basis is one of principal element of decision buildings service life, according to " 5 times of laws " of generally acknowledging in the world, the insufficient buildings of weather resistance, maintenance cost during its operation will be 5 times a construction cost, therefore, the weather resistance of raising tubular pile concrete has important engineering application value and good social benefit.
Summary of the invention:
The technical problem that the present invention solves is from raw-material design of components and two aspects of preparation technology, and the preparation high-durability tubular pile concrete provides assurance on the material for improving the pile tube weather resistance.
The know-why of foundation of the present invention is tightly packed principle, utilize the filling effect of mineral admixture volcanic ash reinforcing effect and different minerals admixture complex effect, different size component, reduce the concrete material subsurface defect significantly, give the tubular pile concrete high strength, high elastic coefficient, good ductility, high permeability resistant, high impact properties, high-durability.
The present invention relates to a kind of preparation of material of construction, i.e. the preparation of high-durability tubular pile concrete.Each quality of material ratio is 1～1.2 part of gelling material, 1.4～1.8 parts of fine aggregates, 2.5～3.5 parts of coarse aggregates, 0.01～0.02 part of high efficiency water reducing agent, water 0.23～0.28.Gelling material is by cement, breeze, and flyash, silica flour is formed, and its quality group becomes, 0.8～1.2 part of cement, 0.1～0.2 part of breeze, 0.1～0.2 part in flyash, 0.2～0.3 part of silica flour.Cement is that strength grade is not less than 42.5 ordinary Portland cement.Fine aggregate is the composite of special fine sand and medium sand, and its quality group becomes 0.5～1 part of the special fine sand of fineness modulus 0.7～1.0,2～3 parts of the medium sands of fineness modulus 2.4～2.6.
Secondary stirring technology is adopted in concrete preparation, drops into gelling material, fine aggregate and high efficiency water reducing agent earlier, adds 70～80% of mixing water total amount, stirs 20～25s, subsequently, adds coarse aggregate and 20～30% remaining mixing waters, and stirring gets final product discharging.
The present invention has 3 characteristics: 1. high strength, high elastic coefficient, high impact properties.Gelling material, fine aggregate, coarse aggregate, particularly the special fine sand of fineness modulus 0.7～1.0 mixes, bridge joint effect between the medium sand that plays gelling material and fineness modulus 2.4～2.6 on the material size, make all materials form the entity of continuous grading on the whole, thereby realize the material densification.The complex effect of mineral additive and silica flour participate in chemical reaction can both effectively improve concrete physical and mechanical property.2. good ductility, high permeability resistant, high-durability.Mixing of mineral additive during gelling material is formed and silica flour, its complex effect can effectively reduce concrete subsurface defect, as improves the pore structure feature, reduces porosity, reduces the amount in harmful hole; Improve each material interfacial transition zone performance, reduce the interfacial transition zone size, reduce portlandite directional profile in the interfacial transition zone; Secondary stirring technology can effectively be improved the not homogeneity of interface zone of transition between coarse aggregate and cement stone.3. environmental protection and energy saving.The present invention makes full use of other trade wastes, reduces cement consumption, thereby reduces Cement industry to the consumption of the energy, resource and the quantity discharged of minimizing CO2, helps the Sustainable development of building material industry.
The present invention is applicable to the pile tube that preparation has higher requirements to weather resistance, as the pile tube that uses in erosion environment.
