Degradation of the Bond Strength Between Rebar and Concrete due to the Impressed Cathodic Current

Journal of marine science and technology (2009)

Jiang‐Jhy Chang Weichung Yeih Ran Huang

In this study, the degradation of the bond strength between the steel rebar and concrete by the impressed cathodic current was investigated. Experimental results showed that the bond strength degraded as the charging current density and the polarization time increased basically. A new parameter representing the total transferred electrons per unit protected area was proposed, and the bond strength was found to decrease as the parameter increased after some value.

Applications of domain partition in BEM for solving the vibration problem of a rod subjected to a spatially distributed harmonic loading

Journal of the Chinese Institute of Engineers (2001)

Jiang‐Ren Chang Weichung Yeih

Abstract In this paper, the dual boundary element method is used in conjunction with the domain partition to solve the vibration problem for a rod subjected to a time harmonic loading. It is shown that when the constraint equations are all included in the solver and the real part singular or real part hypersingular equation is used alone, the spurious resonance that may arise can be eliminated by using the singular value decomposition method. Even when the complex singular or hypersingular equation is used, if the structure is complicated or heterogeneous, domain partitioning and a subsequent parallel treatment become necessary, this gives rise to both spurious and “pseudo‐spurious” resonance. Three iteration schemes that are often used in parallel computation are shown to be inadequate here, and a new “mixed method” approach is proposed. Three benchmark examples are then used to show how the proposed approaches can be applied to eliminate various kinds of spurious and pseudo‐spurious resonance.

The Influence of Aggregate Size and Binder Material on the Properties of Pervious Concrete

Advances in Materials Science and Engineering (2014)

Tun Chi Fu Weichung Yeih Jiang Jhy Chang Ran Huang

Specimens were prepared by altering parameters such as aggregate sizes, binder materials, and the amounts of binder used and were subsequently tested by using permeability, porosity, mechanical strength, and soundness tests. The results indicated that the water permeability coefficient and connected porosity decreased as the amount of binder used increased and increased with increasing aggregate size. In the mechanical strength test, the compressive, splitting tensile, and flexural strengths increased as the amount of binder used increased and decreased with the increase of aggregate size. Highly viscous binder enhanced compressive strength, water permeability, and the resistance to sulfate attacks. In the mechanics and sulfate soundness tests, the mix proportion of alkali-activated slag paste used in this study exhibited a superior performance than the Portland cement pervious concrete (the control) did, but the difference in water permeability between the two types of concrete was insignificant. The mix proportions of cement paste containing 20% and 30% silica fume exhibited less mechanical strength than the control did. Moreover, compared with the control, the cement paste containing silica fume demonstrated poor resistance to sulfate attacks, and the difference in the water permeability between such specimen and the control was not noticeable.

ASSESSMENT OF CHLORIDE DIFFUSION IN HIGH STRENGTH CONCRETE USING THE ACCELERATED IONIC MIGRATION TEST

Journal of the Chinese Institute of Engineers (1997)

Ran Huang Weichung Yeih

ABSTRACT The diffusivity of chloride ions through high strength concrete has been studied. A simple potential difference has been applied to accelerate the CI− diffusion through concrete. Test variables have included the strength of concrete, the applied electrical potential, and the pozzolan. A modified equation and numerical method are used to compute the diffusion coefficients of chloride ions in concrete. Test results show that the effective diffusion coefficients are between 2.53×10−14m2/sec and 9.84×10−14m2/sec for concrete with compressive strength between 62.5MPa and 91.1MPa. The slag refines the internal pores of concrete by pozzolanic reaction, and reduce the chloride ion diffusion in concrete. For high strength concrete, the computed effective diffusion coefficients are not significantly affected by the applied electrical field intensity.
