  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Alkali-silica reaction in concrete containing recycled concrete aggregates

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

  • A study of the coagulation of kraft effluent by sea water

    Creator:
    Andrews, Ben Neal
    Abstract:
    The coagulation of effluent from the kraft pulping and papermaking process was investigated. The amount of material coagulated from saline mixtures of the effluent is determined as a function of time, salinity, kraft effluent concentration, and mixture pH. Individual sources of salinity include sea water and several different solutions of...

  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • In situ measurement of the benthal oxygen requirements of tidal flat deposits

    Creator:
    Crook, Gene Ray
    Abstract:
    In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

  • The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

    Creator:
    Martin, Duane Collins
    Abstract:
    A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

  • Assessing Durability of Concrete and Ettringite Accelerated Cementitious System

    Creator:
    Sarkar, Anika T.
    Abstract:
    The goal of the first part of this project was to investigate the influence of aggregate source and entrained air on the transport properties of concrete. Currently, there are several ASTM standards available that provide systematic procedures to evaluate mass transport properties of concrete. ASTM C642-13 (ASTM 2013), often referred...

  • Internal curing of high-performance concrete for bridge decks

    Creator:
    Deboodt, Tyler
    Abstract:
    High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...
