Introduction: Ferrocement is a low-cost material that can be utilized as replacement for expensive fiber-reinforced polymer (FRP), which generally used retrofitting structural and non-structural reinforced concrete members. The objective of this paper to investigate the effectiveness wire mesh in flexural members such beams. It also investigated capacity beams, are with partial or complete regu...

The resin-bonded bridge is a relatively new clinical technique that has had favorable clinical reports. Recently, new materials and techniques have been developed which may improve the retention of resin-bonded bridges. This article reviews recent developments concerning resin-bonded bridges, present a case report, and give practical suggestions regarding the fabrication of resin-bonded bridges.

Silica-bonded N-propyldiethylenetriamine (7) is employed as a recyclable heterogeneous solid base catalyst for the synthesis of 2-amino-3,5-dicarbonitrile-6-thiopyridines through pseudo four-component condensation reaction between aromatic aldehydes, malononitrile, and 2-amino-thiophenol in refluxing ethanol. Silica-bonded N-propyldiethylenetriamine showed much the same efficiency when used in ...

The effect of strain levels on the corrosion resistance an enamel-coated steel rebar is experimentally investigated in this study. Enamel coating was applied surface a by using wet process. A gauge attached coated to record and plastic container mounted for electrochemical tests. stress-corrosion test set-up designed conduct tensile tests simultaneously. considered include 0 µε, 300 600 900 µε ...

We investigate the addition of stiffness to the lattice model of hydrogen-bonded polymers in two and three dimensions. We find that, in contrast to polymers that interact via a homogeneous short-range interaction, the collapse transition is unchanged by any amount of stiffness: this supports the physical argument that hydrogen bonding already introduces an effective stiffness. Contrary to possi...

A classification of the hydrogen fluoride H-F-bonded interactions comprising a large number of molecules has been proposed by Espinosa et al. [J. Chem. Phys. 117, 5529 (2002)] based on the ratio /Vr(c)/ / Gr(c) where /Vr(c)/ is the magnitude of the local potential-energy density and Gr(c) is the local kinetic-energy density, each evaluated at a bond critical point r(c). A calculation of the rat...
