Freeze-Thaw Durability Of Pervious Concrete, Carson B. Demille
Freeze-Thaw Durability Of Pervious Concrete, Carson B. Demille
Theses and Dissertations
Although the use of pervious concrete is expanding, only a limited number of scholarly papers have been published on the resistance of pervious concrete to deterioration under frost action. Based on this need for additional research on the durability of pervious concrete in cold regions, the objective of this research was to evaluate the resistance of pervious concrete to degradation during freeze-thaw cycling under different soil clogging and water saturation conditions. The laboratory research associated with this project involved three primary measures of pervious concrete performance, including freeze-thaw durability, compressive strength, and permeability. Testing associated with freeze-thaw durability involved two …
Evaluation Of Laboratory Durability Tests For Stabilized Subgrade Soils, John Wesley Parker
Evaluation Of Laboratory Durability Tests For Stabilized Subgrade Soils, John Wesley Parker
Theses and Dissertations
The Portland Cement Association commissioned a research project at Brigham Young University to compare selected laboratory durability tests available for assessing stabilized subgrade materials. Improved understanding of these tests is needed to enable more objective selection of durability tests by design engineers and to facilitate more meaningful comparisons of data obtained for different stabilizer treatments using different evaluation procedures. The laboratory research associated with this project involved two subgrade materials, four stabilizers at three concentrations each, and three durability tests in a full-factorial experimental design. The two subgrade soils used were a silty sand and a lean clay, while the …
