Automated Rapid Particle Investigation Using Scanning Electron Microscopy
(Oklahoma State University, 2013-12-01)
The chemical composition of fly ash particles has been known to vary significantly depending on a number of factors. Current bulk methods of investigation including X-Ray Fluorescence and X-Ray Diffraction are thought to ...
Performance based testing for air entrainment and total heat of reclaimed fly ash
(2021-07)
As coal combustion energy plants are being converted to natural gas, the tons of fly ash produced in the United States has dramatically decreased. The current demand in fly ash supply can be mitigated with the introduction ...
Predicting fly ash performance in concrete from particle characteristics
(2020-05)
While fly ash is widely used as supplementary cementitious material (SCM) in concrete, the demands of fly ash have been increased in producing high-performance concrete. Fly ash can contribute to the strength gain and ...
Improvement of Phosphorus and Heavy Metals Retention in Stormwater Treatment
(Oklahoma State University, 2006-07-01)
The objectives of this study were to find filter media with high phosphorus sorption and adequate hydraulic conductivity for use in bioretention cells, and to evaluate the improvement of heavy metals retention in sandy ...
Investigation of the Quality Control of Waste Products for Concrete
(2019-05)
This work uses testing for the quality of waste products in the production of concrete. This work will look at two different waste products. The first is Pulp Cure, a recently developed method for wet curing concrete. The ...
Investigating resistivity testing as a method for quality control of concrete mixtures
(2018-05)
Concrete is a composite material. It is a mixture of cement, sand, rocks and water. It is the second largest consumable product in the world. Unfortunately, many of the concrete structures before completing the designed ...
Comparing concrete performance using conventional and alternative coal ash
(2022-07)
Fly ash is widely used as a supplementary cementitious material in concrete as it can contribute to strength gain and increased durability of the concrete. The coal ash production volume has decreased in recent years due ...
