Description
Technical field
Present invention relates particularly to a kind of blast furnace resistance rust anti-corrosion non-shrinkage concretes and preparation method thereof, belong to construction material
Technical field.
Background technology
For marine structure, sea sand building and varieties in saline-alkali areas building, contain a large amount of chlorine in coastal area or ambient enviroment
Ion and sulfate ion easily generate corrosion effect to reinforcing bar and concrete, reduce concrete basicity, destroy the blunt of rebar surface
Change film, cause steel bar corrosion and expansion, further result in crack and peeling, structure uses function and mechanical property
It can constantly deteriorate.For this purpose, expert proposes that various measures improve the anti-corrosion ability of concrete structure both at home and abroad, wherein in concrete
It is exactly a kind of economical and practical, easy construction effective measures to add corrosion inhibitor.
Concrete foundation is chronically in the environment of this high chloride ion and sulfate ion, can be because Chloride Attack is mixed
Solidifying soil leads to reinforcement corrosion and makes structure that Random early Detection occur, loses the endurance quality of structure, reduce actually making for engineering
With the service life, so must take into consideration the anti-corrosion of concrete structure in terms of mix Design, it has also become in Practical Project
Major issue.
Currently, the thinking of anticorrosive mix Design is " low hydration heat, low internal stress, low early strength ",
Cementitious matter of the low hydration heat cement as mass concrete is used, keeps the early stage internal stress of concrete low, while early stage
Intensity is also very low.And it is more demanding for strength grade and require tighter mass concrete, use existing the construction period
Match ratio be related to technology and be extremely difficult to coastal area high-strength anti-corrosion performance requirement, and the performances such as final concrete strength are not yet
It can meet the requirements.
Non-shrinkage concrete is more in foreign study at present, has been the product of relative maturity, such as American scientist
Lossier is prepared for chemical pre-stressed concrete before and after 1936 using the expansion of entringite, has established important base
Plinth.Then, the U.S. starts to research and develop expansive concrete.1958, American's A. Klein Gordon equations succeeded in developing a kind of aluminium sulfate type
Cement is named K cement, and achieves the patent of expanding cement.The cement started to be used for expansive concrete in 1963, and
Mass production is promoted the use of in various structures.
Between 1965~1972 years, Japan has purchased U.S.'s K-type expanding cement patent, and on this basis, succeeds in developing
Sulphoaluminate expander (Calcium Sulfo-Aluminate, abbreviation CSA).1970, the Japanese fields little Ye company also successfully opened
Lime swelling agent, later stage the 1990s are sent out, the P.K.Mehta in the U.S. etc. is to solve temperature difference of mass concrete crack
Problem, it is proposed that the imagination of 5%MgO, and the magnesia class swelling agent etc. that has thus been born are mixed in cement.Domestic swelling agent
Technology development is later, but makes rapid progress.
The famous Crack Control expert Wang Tiemeng professor analysis and summary personal experiences in China and survey data both domestic and external think：
The Causes of Fracture of mechanism object in engineering practice accounts for about 80% caused by belonging to deformation variation (temperature, contraction, differential settlement)
More than；Belong to and accounts for about 20% or so caused by load.Cast-in-place concrete structure is before normal use, i.e., frequent in construction period
Generate crack, at this point, structure usually not yet bears whole load under normal use, this crack mostly because of indirectly-acting such as
Non- load (contraction, temperature etc.) causes, this crack is known as concrete " construction period indirect crack ", and construction period is split indirectly
The main reason for seam occurs is the contraction of concrete, and therefore, it is that solution is this that swelling agent is added in concrete preparation process
Problem best bet.Swelling agent is mainly used in material production, and relatively conventional is cement expansive material and refractory material
Swelling agent.With unshape refractory hardening process, the shrinkage character of Chang Yinwei raw material itself causes to crack concrete.Draw
It is to introduce quantitative volume expansion with swelling agent, the shrinkage value of compensating material itself prevents material from shrinkage cracking, shadow occur
Ring its structure, function and appearance.In recent years, as composite material researches and develops use extensively, intumescent material also obtains industry-by-industry
Pay attention to, is widely used in the manufacturing of material.
Domestic market also lacks multiple functional, and the concrete product of excellent combination property, many key projects must not
It does not spend huge sums and induces one from foreign countries, it is not only expensive, application risk is also added, is researched and developed thus in a kind of blast furnace project, such as stake
The concrete material of the construction demand of the construction parts such as core basis, frame foundation, Equipment Foundations is of great immediate significance.
