Description
Technical field
The invention belongs to field of civil engineering, particularly to a kind of water proofing property ECC and carbon cloth composite consolidation material and use thereof
Method.
Background technology
In Reinforced Concrete Members with Flexure such as field of civil engineering, the beam of building (espespecially house, bridge etc.), plates, due to
Structure is aging or the factor such as upper load increase, shows Lack of support, even by bent face concrete cracking.From economic angle
Degree and construction complexity consider, engineering typically will not directly be changed flexural member, but take certain reinforcement measure.
At present frequently with Enlargement of Section, bonding steel plate method or affixing carbon fabric method in engineering.Wherein affixing carbon fabric method, by
Fast in speed of application, do not change constructional appearance, and the most do not increase the advantages such as dead load, there is the highest Practical valency
Value.But the fastness problem of affixing carbon fabric is solved the most well, when the amount of deflection of flexural member increases, often
Occur coming unglued phenomenon, causes carbon cloth to lose efficacy.Meanwhile, carbon cloth also has the shortcoming be afraid of naked light, be afraid of shock.It addition, carbon
The crack that fiber cloth produces after can not effectively covering flexural member cracking, it is impossible to stop external water ground to invade, do not stop by curved
The corrosion of component inside reinforcing bar.
ECC (Engineered Cementitious Composites, high ductility fiber reinforced cement-based composite material are called for short ECC)
As a kind of concrete material with certain strain-hardening property, self there is the adaptability to changes that comparison is high, may be used for reinforcing
The Reinforced Concrete Members with Flexure of Lack of support.But ECC cost is the highest, directly ECC is used as the reinforcing of flexural member
Material is uneconomic.
Summary of the invention
The purpose of the present invention is contemplated to solve the problems referred to above, it is provided that one both can avoid carbon cloth to come unglued inefficacy, again can
The crack enough stoping the Reinforced Concrete Members with Flexure such as external water Yan Liang, plate invades, and the internal reinforcing bar of protection is from the water proofing property of corrosion
ECC and carbon cloth composite consolidation material and using method thereof.
The water proofing property that existing ECC pours material is not enough, along with external water invade, cause the armored concrete such as Yuan Liang, plate to be subject to
The steel bar corrosion of curved component inside increases the weight of, and service life significantly shortens.In order to solve this problem, in research, it is firstly added thin
Water preparation carries out hydrophobically modified to ECC so that the cracking mask behind ECC surface and generation crack has certain hydrophobicity.When being subject to
