...Gilson Lomboy; Kejin Wang The present research is aimed at investigating effects of concrete properties, particularly concrete rapid chloride permeability, strength, and air void parameters, on freezing-thawing (FT) resistance. In this study, concrete mixtures are made with different types...

.... Measurements were taken before and after exposure on 100 mm diameter disks, approximately 25 mm thick. The dynamic modulus of elasticity (Ed) was measured using resonant frequency techniques. Fluid penetrability of the disks was characterized by air permeability index (API) and rate of water absorption...

... Hammerfest sediments increased substantially. In order to achieve the lowest total net transport of contaminants through the material, S/S recipes for environmental projects should not only be optimized with regard to physical strength, but also with regard to leaching and permeability.

... on the measured water vapor permeability or permeance of various commonly used building materials or components. The results presented in this paper were discussed in the ASTM technical task group to underline the importance of various corrections for the calculation of water vapor transmission properties...

... by weight and silica fume: 10 % of solids by weight) with water/solid ratio of 1.0 are first determined. In addition, penetration performance of the suspension into fine to medium sand specimens having different relative densities is investigated. Unconfined compression and permeability tests were performed...

... to the conventional test (ASTM D 2726) [1] utilizing the saturated surface dry (SSD) method. Permeability (ASTM PS 129-01) [4] measures an HMA mixture's ability to allow moisture to pass through it, which in turn is related to the mixture's connectivity of void space. For this reason permeability was chosen...

... and thus the development of a scaffold requires an optimization process. The article reviews several scaffold fabrication processes to highlight the complexity of the field. Issues related to porosity, permeability, and the need for adequate diffusion characteristics are discussed. Several previous studies...

... have caused the drastic increase in the strength of Mixture S-2 at late ages. The respective water permeability values of Mixtures S-2 and S-3 decreased from 68 and 33 μm/s at 63 d to 6 and 12 μm/s at 227 d due to the improvement of microstructure of these CLSM mixtures. 31 03 2003 23 09...
