Synthetic Fiber Reinforced Concrete in Marine Environments and Indirect Tension TestUnknown Date (has links)
An experiment was conducted to evaluate the durability, toughness, and strength
of Synthetic Fiber Reinforced Concrete after being immersed in five separate
environments for one year at FAU SeaTech. The specimens were molded and reinforced
with two-inch Polypropylene/Polyethylene Fibers in a concrete aggregate matrix and
were cut into identical sizes. Some of these environments had accelerated parameters
meant to increase degradation to simulate longevity and imitate harsh environments or
seawater conditions. The environments consisted of: a high humidity locker (ideal
conditions), submerged in the Intracoastal Waterway (FAU barge), seawater immersion,
a wet and dry seawater immersion simulating a splash/tidal zone, and another in low pH
seawater. The latter three were in an elevated temperature room (87-95°F) which
produced more degradative properties. The specimens were monitored and the
environments were controlled. The specimens were then evaluated using the IDT test
method using force to initiate first-cracking and post-cracking behaviors. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

Strength and toughness of HDPE fiber reinforced aggregate concrete as a sustainable construction materialUnknown Date (has links)
An experimental study was conducted on the strength and toughness characteristics of concrete made from recycled aggregate, cement and fly ash reinforced with reclaimed high density polyethylene plastic (HDPE) fibers. The objectives of the investigation were: (1) to evaluate the performance of a sustainable concrete containing up to 90% recycled materials; (2) to determine the variation of strength and toughness with a Fiber Factor incorporating length, width and amount of HDPE fibers; (3) to identify the best performing mix design based on tensile strength and toughness and (4) to provide some guidelines for the use of this sustainable composite in Civil Engineering construction. The results showed that the HDPE fiber reinforcements did not improve the compressive strength of the mixture. However, HDPE fibers improved the ductility and toughness which may be beneficial for structural and pavement applications. / by Roody Numa. / Thesis (M.S.C.S.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

Fire Performance of Reinforced Concrete SlabsLevesque, Adam Paul 28 April 2006 (has links)
In the United States design for fire safety follows a prescriptive code-based approach. Building codes detail the types of construction materials, assemblies, and fire suppression systems that are required for various building types. This prescriptive method has prevented structural engineers from exposure to performance-based design approaches for fire safety. The motivation for this thesis was to increase the awareness of the structural engineering field to the concepts behind structural design for fire safety. Extensive research has been published on the performance of structural steel in fire conditions, and simplified design tools already exist to describe its behavior. Such tools do not exist for reinforced concrete structures. Research on concrete has been more focused on material properties rather than structural performance. This thesis presents a simplified design tool which assesses the fire performance of reinforced concrete. An Excel-based spreadsheet application was developed for thermal analysis of concrete slabs. It accounts for different aggregate types, slab thicknesses, and fire exposures. Several analyses were performed with the spreadsheet application to examine the affect slab thickness and aggregate types have on the fire performance of concrete slabs in standard and natural fires. The results were compared with published test data and finite element software simulations to benchmark the accuracy of the proposed tool. Furthermore, methods for the design of reinforced concrete slabs in fire conditions are presented.
