Direct three dimensional observation of the microstructure and chemistry of C3S hydration
(2015-12)
Although portland cement has been used for over a hundred years as the binder in concrete, the basic mechanism of hydration is still not well understood. Progress has been halted for the fact that it is challenging for ...
Influence of time dependent properties and temperature effects on the performance of composite bridge girders
(2019-12)
This dissertation seeks to understand the mechanical properties of concrete, and its interaction with steel bridge girders with the purposes of deepening our understanding of the behavior of steel girder bridges made ...
Sustainability in agricultural practices: Carbon footprint of agricultural groundwater pumping, and microbial denitrification in agricultural soils
(2022-12)
This study aims to identify agricultural energy, water, and nutrient management practices that decrease greenhouse gas (GHG) emissions from irrigated agriculture. Irrigation water and agricultural improvements like fertilizer ...
Soil-cement base course
(1957-05)
Scope of Study: Soil-cement was first used in road construction in the U.S.A. in 1935 and since then has been used on an increasing scale. The ways in which soil-cement may be used successfully is treated in this study. ...
Development of a new tensile stress model for expansive soils
(2015-12)
The problems associated with drying shrinkage are worldwide, and cause great damage to highways and buildings constructed on expansive soils. Literature review indicates that the development of shrinkage crack is governed ...
