Sensitivity Of Rheological Properties Of Cement Paste With Scc Consistency, Azadehalsadat A. Asghari Jan 2018

Sensitivity Of Rheological Properties Of Cement Paste With Scc Consistency, Azadehalsadat A. Asghari

Doctoral Dissertations

"Robustness, which is defined as the capacity of a mixture to tolerate small variations in constituent elements, mixing parameters or temperature that are inevitable with production at any significant scale, is a key property to expand the practical implementation of self-consolidating concrete (SCC). At the first step, the effect of different amount of water, amount of superplastizer, mixing time, mixing speed and the addition time of superplastizer on the rheological properties of cement pastes with SCC consistency, has been evaluated. Two different SCC mix design concepts, the powder-type and VMA-type were selected for this research. The results show that the …


Evaluation Of Cracking Indices For Asphalt Mixtures Using Scb Tests At Different Temperatures And Loading Rates, Katie E. Haslett Jan 2018

Evaluation Of Cracking Indices For Asphalt Mixtures Using Scb Tests At Different Temperatures And Loading Rates, Katie E. Haslett

Honors Theses and Capstones

In recent years, there has been a shift towards implementing performance based pavement specifications (PBPS) to increase reliability of asphalt concrete mixture specifications and enhance service lives of roadways. Several of the performance indices used in PBPS are based on the asphalt mixture fracture tests. There is an increasing need for a better understanding the effects of temperature and loading rate interdependency for fracture properties of asphalt mixtures. The goal of this study is to build upon previous work conducted during a Summer Undergraduate Research Program (SURF) project entitled, “Exploration of Temperature and Loading Rate Interdependency for Fracture Properties of …
