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 ... -
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 ... -
Engineering Properties of Stabilized Subgrade Soils for Implementation of the AASHTO 2002 Pavement Design Guide (FHWA-OK-08-10 2185)
(2009-6)A comprehensive laboratory study was undertaken to determine engineering properties of cementitiously stabilized common subgrade soils in Oklahoma for the design of roadway pavements in accordance with the AASHTO 2002 ... -
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 ... -
Improving concrete performance through the use of blast furnace slag (FHWA-OK-00-01) 2136
(2000-8)A laboratory testing program was undertaken to evaluate the performance of ODOT Class AA and Class A concretes, specifically containing Oklahoma cements and aggregates, and utilizing partial replacement of portland cement ... -
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 ... -
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 ... -
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 ... -
Resilient moduli of raw and stabilized aggregate bases and evaluation of layer coefficients for AASHTO flexible pavement design volume I (FHWA-OK-98-05) 2199
(1998-8)A comprehensive study involving laboratory testing of resilient moduli (MR) of aggregate materials, determination of layer coefficients, and their application in AASHTO flexible pavement design was conducted. Three coarse ... -
Tube Suction Test for Evaluating Durability of Cementitiously Stabilized Soils (FHWA-OK-11-05 2215)
(2011-6)In a comprehensive laboratory study, different tests namely, unconfined compressive strength (UCS) at the end of freeze-thaw/wet-dry (F-T/W-D) cycles, resilient modulus (Mr) at the end of F-T/W-D cycles, vacuum saturation, ...
