An Experimental Study On Adhesive Properties Of High-strength Concrete And High-strength Steel

Application of high-strength steel and high-strength concrete can significantly saveenergy and resources, and promote the construction of development and reform,promote the development of China’s economy and society. Important way of usinghigh-strength steel and high-strength concrete is to take environmental protection,energy conservation, sustainable development path.Anchoring effect between the steel and concrete, are these two materials can worktogether to bear the load of the important reasons. Steel and concrete action byanchoring, mutual transfer force to bear loads. Anchoring is the reinforced concretestructure of the basic conditions for carrying the force anchoring mechanism of actionresearch is also reinforced concrete structure theory of basic questions.Currently, the problem common to the anchor material and theoretical studies havebeen more test areas, and related specifications have been promulgated. However,the study of high-strength materials anchor is still very small, involving theapplication development of high strength materials, how to reduce the length of theanchor, the anchor optimization of existing theory becomes increasingly important.This paper mainly studies bonding and mechanical anchoring high-strengthconcrete and high-strength steel anchor between. By drawing experiment withdifferent parameters, according to the experimental phenomena and data, summedbond anchoring characteristics of high strength reinforced with high-strength concreteand mechanical anchoring properties, explore the different factors that affect theperformance of its anchorage.In this paper, the use of local building materials in Tianjin, through concrete mixtests have been compared with C80concrete; On this basis, the design of the33drawing specimens were considered concrete strength, bar diameter, cover thickness,length and anchoring rate and other parameters affect the stirrup anchorage strength ofthe bond, the bond explore anchorage performance of high strength reinforced withhigh-strength concrete; drawing by33specimens were considered concrete strength,bar diameter, cover thickness, length and stirrup anchorage rate parameters on themechanical strength of the anchor, the anchor to explore the performance ofhigh-strength steel and high-strength concrete machinery.
