Filter by Keyword7 report(s) found with admixtures in the keywords field 1 - 7 of 7 This research explores the influence of thermo-mechanical beneficiation methods on the physicochemical characteristics and reactivity of fly ashes disposed of in landfills (LFAs) obtained from power plants in Wyoming and Colorado, USA. An in-depth assessment was conducted on the mechanical and performance... The condition of concrete on bridge decks is one of the most costly parts of Wyoming Department of Transportation's budget and the cost of maintenance can result in inadequate roads or costly premature repairs. This proposal evaluates critical factors relating to early age shrinkage and proposes combining... Many laboratory studies have shown erratic flexural strength results among replicate specimens of fiber reinforced concrete (FRC). As a result, repeatability of results was very challenging. Given this issue, it would be very difficult for design engineers to make reliable claims about the performance... An experimental research study was conducted to develop optimized concrete mixtures for jointed plain concrete (JPC) pavements and field evaluation of newly constructed JPC pavement sections along South Dakota highways.
Using South Dakota aggregates, different concrete mixtures were assessed for optimum... The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion. The high amount of confining steel may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or reduces concrete placement... Recent studies have shown that the use of self-consolidating concrete (SCC) results in improved finished quality, increased production efficiency, and reduced labor cost. Because of the favorable properties that SCC exhibits, the Federal Highway Administration and the precast concrete industry have been... This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures... |
