Predicting the Permeability of Pervious Concretes from Planar Images
This paper discusses the reconstruction of three-dimensional material structures of pervious concretes using two-dimensional digital images obtained from actual specimens, and computational permeability predictions using these reconstructed three-dimensional material structures. The computer programs developed at the National Institutes of Standards and Technology (NIST) are used to obtain thre...
متن کاملPermeability of Natural Clay Liners: Effect of Accelerated Permeability Testing on Soil Structure
A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted. The specimens were then freeze-dried to preserve their post-test ...
متن کاملDetermination of Compacted Clay Permeability by Artificial Neural Networks
In many civil engineering practices like design of landfills, earth dams, pavements and agricultural issues, it is necessary to know the permeability coefficient of soils. In situ tests are frequently used to predict permeability of the soil. On the other hand, high ability of Artificial Neural Networks (ANNs) in prediction of nonlinear behavior has attracted the attention of many researchers. ...
متن کاملCompressive Strength, Chloride Permeability, and Freeze-Thaw Resistance of MWNT Concretes under Different Chemical Treatments
This study investigated compressive strength, chloride penetration, and freeze-thaw resistance of multiwalled carbon nanotube (MWNT) concrete. More than 100 cylindrical specimens were used to assess test variables during sensitivity observations, including water-cement ratios (0.75, 0.5, and 0.4) and exposure to chemical agents (including gum arabic, propanol, ethanol, sodium polyacrylate, meth...
متن کاملPermeability Characteristics of Compacted and Stabilized Clay with Cement, Peat Ash and Silica Sand
The present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. In order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...
