Creation of cracks of known sizes in reinforced concrete beams and performance evaluation of silane in concrete bridge decks
(2020-05)Cracks are a major concern for the durability of concrete as they allow the harmful chemicals from outside to penetrate the concrete surface. Investigating the effect of various crack sizes is vital to further evaluate the ... -
Durability evaluation of concrete sealed with polyurea polyaspartic coatings
(2020-05)For this project, the performance of various polyaspartic coating materials was investigated. Motivation for this study was to assess various options for the containment of concrete within bridge parapet walls to prevent ... -
Effect of wet curing duration on long-term performance of concrete in tidal zone of marine environment
(SpringerOpen, 2015-12)A proper initial curing is a very simple and inexpensive alternative to improve concrete cover quality and accordingly extend the service life of reinforced concrete structures exposed to aggressive species. A current study ... -
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 ... -
Investigation of MMFX Reinforcing Steel and the Admixture IPANEX for Use In Bridge Decks
(Oklahoma State University, 2004-05-01)The purpose of this study is to evaluate MMFX reinforcing steel and the admixture IPANEX for use in bridge decks. An experimental program was developed to test certain properties of MMFX steel and IPANEX. Fresh and hardened ... -
Quantifying the efficiency and quality of air void distributions in concrete
(2022-05)This work establishes new ways to measure and examine the air bubble distribution within concrete. This is important to provide freeze thaw durability and resistance to oxychloride formation. These bubbles decrease the ... -
Stability and Quality of Air Void Systems in Concretes with Superplasticizers
(Oklahoma State University, 2012-12-01)This study examines the effects of combining different polycarboxylate superplasticizers with different air entraining agents in modern concrete. A novel testing method was invented for analyze the changes over time in the ... -
TEST METHODS FOR USE OF RECYCLED ASPHALT PAVEMENT IN ASPHALT MIXES (FHWA-OK-12-01 2223)
(2012-2)Usage of recycled asphalt pavement (RAP) in the construction of new pavements has increased in recent years due to the movement to conserve energy and raw materials, and reuse waste materials. To assess the effectiveness ...
