Chloride Ingress Resistant Concrete: High Performance Concrete Containing Supplementary Composites
1 Associate Professor of Structural Engineering College of Engineering, King Saud University Email: [email protected] Abstract – In Reinforced concrete structures chloride ion penetration is considered to be a major cause of corrosion of reinforcing bars. Conventional concretes fail to prevent the intrusion of moisture and aggressive ions adequately. The use supplementary cementing composite ma...
متن کاملElectrical permittivity and conductivity of carbon black-polyvinyl chloride composites
Electrical conductivity and permittivity of carbon black-polyvinyl chloride composites were studied over a wide frequency spectrum (dc, 1.3 GHz). Conductivity of the bulk composites increases with higher volume fraction of carbon black as expected. However, the functional dependence of the increasing conductivity with carbon black loading is different below and above the percolation threshold b...
متن کاملIntroducing a novel Polyvinyl chloride/Tungsten composites for shielding against gamma and X-ray radiations
Introduction: This study introduces a novel polyvinyl chloride (PVC)/tungsten composites with characterization of their shielding properties by employing different techniques. Methods: The PVC/tungsten composites were produced by employing various weight fractions of tungsten micro-particles including 0, 20, and 40 % wt via melt blending method. In the next st...
متن کاملTin (II) Chloride a Suitable Wetting Agent for AA1200 - SiC Composites
SiC reinforced Aluminum samples were produced by stir casting of liquid AA1200 aluminum alloy at 600-650oC casting temperature. 83μm SiC particles were rinsed in 10g/l, 20g/l and 30g/l molar concentration of Sncl2 through cleaning times of 0, 60, 120, and 180 minutes. Some cast samples were tested for mechanical properties and some were subjected to heat treatment before testing. The SnCl2 rins...
متن کاملReinforced silver chloride as a model material for the study of dislocations in metal matrix composites
Silver chloride containing fibers, spheres and particles of irregular form is used as a model material to study plasticity in metal matrix composites. Matrix dislocations generated upon cooling by the mismatch of coefficient of thermal expansion between the matrix and the reinforcement are observed by transmission optical microscopy after decoration at room temperature by photodissociation of t...
