UNLV Theses, Dissertations, Professional Papers, and Capstones

Fresh, load-dependent, transport, and durability properties of alkali-activated fly ash mortars were studied. The influences of activator concentration, solution-to-binder ratio, curing condition, activator type, and sodium silicate-to-total solution ratio on the properties of the studied alkali-activated mortars were examined. This study was divided in two phases. The first phase dealt with the use of sodium hydroxide as the sole activator. The second phase of the study was divided into two parts, both of which used a combination of sodium hydroxide and sodium silicate as the activator solution. Part I of phase II used elevated temperature curing conditions, whereas part II …

Predicted Performance Of A Skytherm North, A Highly Insulated Building Envelope System And A Frost Protected Shallow Foundation, Kitrina Ann Stratton

UNLV Theses, Dissertations, Professional Papers, and Capstones

How do you design a durable, sustainable, and financeable Net Zero Energy house for a cold weather climate using little or no external energy that is also affordable? Reviewing all of the factors that would influence the design and materials selection of an appropriate response to the issues, the perfect system for housing people, whether it is in response to affordability, durability, comfort, cultural sensitivity, appearance or being locally appropriate, is using some kind of straw bale construction system with an integrated frost protected shallow foundation and a SkyTherm North design.

The focus and intention of this research is to …
