Shearing Test Research Of Beams Reinforced By Micro Steel Fiber-Reinforced High-Strength Concrete Board

Along with the development of construction industry, some early reinforced concrete structure is close to or to the use of residential period in our country, showing problems such as corrosion of reinforcement concrete surface carbide and rebar corrosion such problems, at this time the use of some means necessary for repair reinforcement can have to prolong life effect. maintenance and reinforcement which is closely related with the durability of reinforced concrete structures has become a core problem of construction in the 21st century.Embedded consolidation method is a new type of reinforcement method, unlike traditional reinforcement method.the new consolidation method because of its ingredients in the reinforcement, not inside the structure of headroom and occupy architecture can be very good protection reinforcement material action to improve the durability of strengthening materials, especially in the negative moment out of reinforcement structure, embedded consolidation method has its distinct advantage. Embedded reinforcement method with its unique advantage has become the hotspot, while abroad in the domestic its research has just started. Concrete is the artificial stone widely used in society today.its rely on cheap artificial stone, distribution of a wide range of prices of raw materials, excellent resistance to pressure properties and excellent durability obtained a rapid promotion.This paper adopts 6 different spacing, different water-binder ratio subtle steel fiber high-strength concrete plate embedded reinforced concrete beams, study the shear reinforcement effect. This paper the main work accomplished are:(1) Analyzes the shear of the reinforced concrete beam, identified using high-strength steel fiber concrete board whisper of reinforced concrete beam shear reinforcement method.(2) Compare different water-binder ratio, plates with different spacing of high-strength steel fiber concrete wants whisper of reinforced concrete beams without stirrups deflection, the crack patterns, the influence of shear capacity, this paper puts forward such as strengthening effect the best water-binder ratio and board spacing. (3) Analyzes different water-binder ratio and board space on the influence of reinforcement effect.
