Using interfacial agent prepared with self made expansion component can make the bonding strength of transition zone at 28 d up to 7.8 MPa that is superior to interfacial agent mixed with traditional expansion agent.
The bonding slip behavior between the prestressed concrete pipe pile and pile cap belongs to interfacial bond properties of new and old concrete,which is related to the strength of the concrete of pipe pile and pile cap,surface roughness of pipe pile,interfacial agent and the stress state.
Study on nano particle modified new-old concrete interface agent
3. The influences of several factors including the strength of the concrete, the kind of interface agent, mending orientation and the quantity of containing water in the old concrete on bond strength of the new and old concrete was studied, and the optimum parameter to each factor was obtained, which guides the actual construction in some
The permeability of fresh-old concrete bonding interface in 96 cylindrical specimens is studied experimentally. The influences of surface cleaning measure, bonding agent and surface roughness on the permeability are investigated and the characteristics and mechanical parameters of bonding interface are analyzed.
The influences of the notch groove width, bonding agent on the permeability are investigated and then the equivalent hydraulic fracture width and permeability coefficient and mechanical parameter are analyzed as well.
The influences of several factors on bond seepage properties were discussed, such as interfacial treatment, interface adhesive agent and the surface of old concrete with notch groove. Also the seepage properties and mechanical parameter, such as equivalent hydraulic fracture width, permeability coefficient and seepage law, were explored.
This paper presents the direct shear tests of 129 Z shape new-old concrete bond specimens to study bond shear strength. Two types of specimen are considered: bonding before heating and heating before bonding. The influencing factors such as temperature (25℃-900℃), cooling way, interface roughness and interface adhesive agent on bond shear property are studied.
The role of the liquid interface agent in mechanical properties improvement of modified chalk filled polyolefins
Then, after the idea of Clancey's activity modeling, we discuss the design principles of a situated interface agent.
Initially, our prior work using such a design principle is presented, and then decision-theoretic formulations of an interface agent's activities are provided.
ACQUIRE acts as a softbot or interface agent by presenting users with a view of a single, unified, homogenous data source, against which users can pose high-level declarative queries.
We have implemented an application-independent collaboration manager, called Collagen, based on the SharedPlan theory of discourse, and used it to build a software interface agent for a simple air travel application.
The aim of this study was to evaluate in vivo the cariostatic potential of the resin-reinforced glass-ionomer (Vitremer? core build-up restorative; 3M Dental Product Division) when used as a bonding agent for orthodontic brackets.
Enamel Conditioning for Orthodontic Bonding with a Single-Step Bonding Agent
Interfacial adhesion of sisal/coir hybrid fibre reinforced natural rubber (NR) composites has been characterized by restricted equilibrium swelling technique with special reference to the effects of fibre loading, orientation and bonding agent.
The swelling parameters of NR composites with and without bonding agent were evaluated with three aromatic solvents, namely; benzene, toluene and xylene, by a sorption gravimetric method.
Effect of curing temperature, fibre loading and bonding agent on the equilibrium swelling of isora-natural rubber composites
