Sensor systems for use in reinforced concrete structures.
July 1, 2004... Abstract Whole-life costing and residual service-life prediction of structures require quantitative information on cover-zone properties and threshold values for corrosion initiation and, once initiated, the rate of corrosion. It is clear...

Wedge splitting test on fracture behaviour of ultra high strength concrete.(ultra high strength concrete)(fracture parameters)(crack opening displacement)
July 1, 2004... Abstract The fracture behaviour of ultra high strength concrete (UHSC) with axial compressive strength more than 140 MPa is presented in this paper. Based on the wedge splitting tests with six cubical specimens, the fracture behaviour of...

Flexural response of polymer concrete filled steel beams.
July 1, 2004... Abstract In view of the mounting cost of rehabilitating deteriorating infrastructure, further compounded by intensified environmental concerns, it is now obvious that the evolvement and application of advanced composite structural...

Effectiveness of Class C fly ash as an expansive soil stabilizer.
July 1, 2004... Abstract Fly ash produced in the combustion of subbituminous coals exhibits self-cementing characteristics and can be used in a wide range of stabilization applications. Fly ash treatment can effectively reduce the swell potential of...

Economic aspects of using steel framed buildings with composite floors: case studies from United Arab Emirates.(Emirates Building Systems)(Richard Lees Steel Decking)(methods and materials used for floor construction)
July 1, 2004... This paper is aimed at emphasising the advantages of structural steel in general and composite floor construction in particular. It is typical of engineers in developing countries, such as those in the Middle East, Gulf and Far East, to look at...

Evaluation of building materials recycling on HMA permanent deformation.(hot mix asphalt)(Reclaimed building materials)
July 1, 2004... Abstract Reclaimed building materials (RBM) for recycling are examined on hot mix asphalt (HMA) permanent deformation performance. Four types of aggregates used for mixtures are: (a) 100% river crush stone (CS); (b) 100% RBM; (c) 50%...

Rutting response of hot-mix asphalt to generalized dynamic shear moduli of asphalt binder.(generalized dynamic shear modulus)
July 1, 2004... Abstract In this paper, a stiffness indicator of Generalized Dynamic Shear Modulus (GDSM) of asphalt binders is introduced to study the rutting resistance of unmodified and polymer-modified asphalt binders. Seven binders of two unmodified...

Artificial neural networks for the prediction of shear capacity of steel plate strengthened RC beams.(finite element method)
July 1, 2004... Abstract This paper presents the development of multilayer feedforward artificial neural network models for predicting the ultimate shear capacity of RC beams strengthened with web bonded steel plates. Two models are constructed using the...

Marble behaviour under monotonic and cyclic loading in tension.
July 1, 2004... Abstract The tensile behaviour of marble at failure is analysed. A series of monotonic and cyclic bending tests were carried out in the laboratory on geometrically similar specimens of different size. The strain distribution was monitored...

Post-fire behavior of bond between high strength pozzolanic concrete and reinforcing steel.(high strength concrete)(how to avoide concrete cracking)
July 1, 2004... Abstract This paper investigates the post-fire bond between high strength concrete (HSC) with natural pozzolan (NP) and reinforcing steel. Pullout and cube specimens were cast and cured in water at 23[degrees]C for 40 days before subjected...

Thermo physical characteristics of economical building materials.
July 1, 2004... Abstract An experimental study was carried out in order to determine the properties of local materials used as construction materials. Cement stabilized compressed bricks were tested. The thermal properties of lateritic soil based...

Development of an innovative interlocking load bearing hollow block system in Malaysia.
July 1, 2004... Abstract The paper describes the development of a new interlocking hollow block masonry system appropriate for load bearing masonry wall construction. The developed system is an alternative to the traditional bonded masonry system where...

Retention of movement capability of polyurethane sealants in the tropics.
July 1, 2004... Abstract The adequacy of standard testing methods for movement capability of sealants under tropical conditions was reviewed. A new method involving prolonged exposure to heat and water was proposed and tested. The study has shown that the...

Effect of microstructure of ITZ on compressive strength of concrete prepared with recycled aggregates.
July 1, 2004... Abstract Concrete specimens were prepared with a recycled normal-strength concrete (NC) aggregate, a recycled high performance concrete (HPC) aggregate and a natural aggregate (NA) as control. The influence of these aggregates (recycled...

Simplified mechanical model for evaluating stress in pipeline subject to settlement.(stress calculation formula)
July 1, 2004... Pipe deflection indicators are placed at appropriate intervals along critical underground pipelines, which are susceptible to ground settlement. Based on these deformations of the pipeline, three formulae are developed for estimating the stress...
