Consider its evaluation to concrete durability and generally comprise several as follows：
(1) permeability
Because the various destructive process for influenceing concrete durability nearly all have close relationship with water, in general coagulation
As long as native its permeability is very low, it is possible to the ability that resistance water and corrosive medium are invaded well.Therefore impermeability is considered as
It is the important indicator for evaluating concrete durability.
(2) frost resistance
In cold district, particularly water conservancy project, marine structure, concrete is often to cause concrete deterioration by unfreezing
Principal element.Frost resistance can indirectly reflect that concrete resistance ambient water invades and resist the ability of ice crystal pressure.Therefore it is anti-
Index self-constriction of the jelly property frequently as concrete durability.With high-strength and high performance rod coagulate soil development, the ratio of mud it is further
The addition with fine mineral admixture is reduced, self-constriction institute's occupation of land ratio in concrete shrinkage is greatly increased.It may be said that self-constriction
Turn into an obstacle of Development of HPC to a certain extent.

There is two kinds of the inside and outside environment of rodent sulfuric acid salinity to concrete, it is generally recognized that concrete receives sulfuric acid salt contamination
The result of erosion is to cause volume pole to expand so as to destroy concrete reinforcement containing aluminium, the reaction containing calcium component in sulfate and concrete
Corrosion.In general, steel bar corrosion can be divided into four classes：1. carbonization, makes rebar passivation film lose the condition of presence；2. it is electric
Chemical erosion, enables concrete to lose the steel protection property；3. the erosion of chloride etc., chlorion, sulfate ion and sulphion etc. are all
It is the harmful components that can destroy rebar passivation film, wherein, it is the most violent with the destruction of chlorion.Otherwise performance evaluation is also
Including the performance of physical property such as workability, the mix of concrete.Wherein, the important indicator of energy concrete.Workability is
Evaluate every intensity index, elastic modelling quantity, the toughness of concrete of the property mechanical property high including concrete.High performance concrete leads to
High intensity is often needed, therefore intensity is to evaluate the basic index of high performance concrete.Due to simultaneously because with concrete strength
Increase, fragility increase, the evaluation to the toughness of concrete is also important.
