Experimental Research On Flexural Performance Of Reinforced Concrete Beams Strengthened With CFRP Board

As-cast finish concrete called decoration concrete as well,which is known as highly decorative effect. It is pouring a moldingand and no outside decoration,using of cast-in-place concrete walls as a natural superficial effect to take the facing directly.Therefore it is different from ordinary concrete, the surfacing is smooth, the luster is even, the edges and corners are distinct,there is not collision damage or pollution,it is only It is only in the surface layer or two layers of transparent agent, appearing very natural and grave.As-cast finish concrete is a concrete reinforced concrete construction technology development in one of the topics.Compared to foreign countries in terms,The as-cast finish concrete technology in China started relatively late, As a result,compared with foreign countries there are still a certain gap on the level of research in construction technology, as well as to standardize on.The application of as-cast finish concrete abroad have set up quality control and inspection standards,on the as-cast finish concrete have very strict requirements,however at the present,our country's present national standard is still at the start stage on the explicit quality specification of as-cast finish concrete and the quality flaw origin's research analysis during the construction process.By widely collecting the domestic and foreign correlation data and literature,with the method which unifies the technology and the practice,this paper elaborated its microscopic action mechanism, generalized analysis its quality flaw origin during the construction process ,and has given some concrete prevention measure, to improve the as-cast finish concrete structure quality to provide the effective technical support.Mainly lies in template's key technologies question in view of the as-cast finish concrete appearance quality flaw,selected, the modelling principle and the standard on the template system has carried on the thorough analysis, proposed selected the suggestion based on the different type's as-cast finish concrete with the template system.Simultaneously, proposed the as-cast finish concrete template's quality control standard. This article also proposed to the as-cast finish concrete template's detail node design and the construction the feasible processing method, has solved theas-cast finish concrete surface quality problem effectively.Finally Combining with specific examples of projects,it introduced the fair-faced concrete construction process and construction methods,Verified the proposed methods and analysis of the accuracy and utility of the measures,providing the related experience and the participation for the similar project construction, to promote the as-cast finish concrete to provide the theory and the technical support vigorously.
