Description
Technical field
The invention belongs to civil engineering material technical field, be specifically related to the concrete material of a kind of high anti-stray current, chlorion and carbonization.
Background technology
Along with China's big and medium-sized cities traffic pressure increases day by day, the track traffic of quick environmental protection becomes one of optimal vehicles in city day by day, but it faces following problem: 1, rail tends to reveal stray current, and reinforcing bar in the concrete structure is produced serious corrosive nature; 2, the project subject structure is generally darker apart from the face of land, and it is also comparatively serious corroded by chlorion; 3, the underground environment carbon dioxide content is higher, and is serious to the graphitic corrosion of engineering structure.In a word, the concrete structure of railway traffic engineering is in the corrosive environment of stray current, chlorion and carbonization coexistence.
In order to tackle above environment, the concrete material that is applied to railway traffic engineering generally need possess the performance that is different from normal concrete, generally be on the basis of normal concrete material, with cement is major ingredient, add certain subsidiary material again, the engineering that for example has is singly mixed mineral admixture (flyash or breeze), flyash can be in hydration reaction later stage and the effect of hydrated cementitious product, form a large amount of filler particles, make internal structure constantly closely knit, thereby effectively raise concrete impermeability, performances such as resistivity, but other is to concrete strength, particularly the early strength influence is bigger, especially under the volume condition with higher, influences bigger.Equally, along with the increase of contents of ground slag, early age strength of concrete obviously reduces, and volume is high more, and it is obvious more to descend.So, consider the concrete strength index, it is generally acknowledged that the mineral admixture volume generally must not surpass 30% of binder total amount.The patent of invention that number of patent application 200810046967.8, name are called a kind of high-impedance high-impermeability concrete material and preparation method thereof proposes to add the insulated type polymkeric substance again on the basis of singly mixing mineral admixture, because the insulativity of polymkeric substance, improved concrete resistivity indirectly, but this measure meeting increases production cost greatly.
