Description
Technical field:
The present invention relates to high durability concrete and its processing methods, belong to technical field of buildings.
Background technique:
The durability of concrete refers to that concrete resists the effect of various destructive factors under active usage conditions, long-term to keep strong
The ability of degree and complete appearance.Concrete durability refers to that structure within defined service life, is made in various environmental conditions
Under, does not need extra-pay consolidation process and keep its safety, normal use and acceptable appearance ability.Simply
It says, the durability index of concrete material generally comprises: 1, impervious；2, frost resistance；3, corrosion resistance；4, the carbonization of concrete
(neutralisation)；5, alkali-aggregate reaction.
The main cause of concrete deterioration is now: the freezing of cold day, the effect of the physical-chemical of erosion environment.People's shape
Know together at one: the not variation of portland cement composition, but the permeability of concrete are only its entire endurance issues
It is crucial；Although having significant progress in terms of recognizing and control makes the various physics of concrete deterioration and chemical phenomenon,
Concrete structure but more tends to be not durable.Since load and temperature and humidity act on deformed importance, them are first consisted in
Reciprocation whether can cause to crack.The size of contraction strain is many one side for leading to concrete cracking factor,
His affecting parameters include: 1. elasticity modulus it is lower, elasticity tensile stress caused by a certain size contraction is smaller；2. it is bigger to creep,
Stress relaxation is bigger, and net tensile stress is smaller；3. tensile strength is higher, tensile stress is more than the strength of materials, and the risk for making it crack is got over
It is small.
In summary the factors for reducing concrete cracking, main reason is that its extensibility.When concrete can be born greatly
Deformation without crack when, concrete ductility with higher.Obviously, in order to make the least risk to crack, concrete is not only
Receivable diminution, and should have high ductility, i.e. low elastic modulus, height to creep and high-tensile.
Summary of the invention:
The purpose of the present invention is providing a kind of high durability concrete and its processing method in view of the above problems, effectively mention
