Evaluation of Fiber Reinforced Cement Using Digital Image Correlation

The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile - digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The method outlined provides a simple experimental setup that can be used to evaluate the ultimate tensile st...

Flow of Fiber-Reinforced Cement Slurries at Elevated Temperatures

Cement slurries are used for the construction of oil wells as deep as 30,000 ft (9,000 m). The severe performance requirements for such materials have prompted the search for appropriate fiber reinforcement to improve the slurry’s tensile strength, impact resistance, and fracture toughness, without decreasing its pumpability. A continuum theory for dilute suspensions of large-aspect-ratio parti...

Polylactide-co-glycolide fiber-reinforced calcium phosphate bone cement.

OBJECTIVE To compare the strength of polylactide-co-glycolide fiber-reinforced calcium phosphate bone cement (FRC) with nonreinforced calcium phosphate bone cement (NRC) subjected to simulated dural pulsations in defects larger than 25 cm(2). METHODS Seven NRC and 7 FRC specimens were set in both medium (37.5 cm(2)) and large (50.0 cm(2)) model skull defects while subjected to simulated dural...

Palm kernel fruit fiber reinforced gypsum-cement based wall panels: It’s physical and mechanical characteristics

Agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. A mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. In each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...
