Mixing fiber and power lines in aerial fiber deployments
The last mile of Fiber to the Home (FTTH) and Fiber to the Cabinet (FTTC) aerial fiber deployments often run through crowded environments, where space is at a premium. Street lights, existing telephone poles, power lines, street signs, buildings and trees all jostle for position, especially in urban areas.
Post-cracking performance of recycled polypropylene
Recycled PP fibres were produced through a melt spinning and hot drawing process. • Mechanical properties of recycled PP fibre were studied. • Post-cracking behaviour of fibre reinforced concrete was assessed by CMOD and RDPT.
Crack development in steel-fibre-reinforced concrete members
Within this framework, the aim of this paper is to shed new light on the crack control exhibited by steel-fibre-reinforced concrete (SFRC), having high post-cracking residual strength, in combination with steel rebars. In this regard, 32 tension ties under direct
Recycling of Polypropylene (PP)
Jun 25, 2012 · The Environmental Benefits of Recycling PP. Recycling of polypropylene is emerging as an important, and economically viable, option on a large scale. The main benefit of recycling PP is the reduction in the consumption of raw, finite resources such as oil and propene gas.
Environmental stress cracking: A review - Robeson - 2013
Environmental stress failure of polymers (specifically glassy thermoplastics) is a major failure mode in application end use. The environmental stress failure discussion will primarily be limited to non‐reactive environments. Crystalline polymers and even lightly crosslinked polymers can exhibit similar failure to glassy polymers but often require a much higher external applied stress.
Restrained shrinkage cracking of fiber-reinforced self-consolidating concrete
Fiber-reinforced self-consolidating concrete (FRSCC) is a new type of concrete mix that can mitigate two opposing weaknesses: poor workability in fiber-reinforced concrete and cracking resistance in plain concrete. This study focused on cracking of FRSCC due to restrained drying shrinkage, one of the most common causes of cracking.
Influence of Eichhornia crassipes fibre on water retention and cracking
2020-01-22 · The main objective of this paper is to explore the influence of inclusion of waste WH fibres on hydraulic characteristics (water retention and cracking) of vegetated soils. Three soil series including bare (without vegetation) soil (BS), soil + grass (SG) and soil + grass + WH-fibre …

PVC vs. PET vs. PP | Which Material should I use for Packaging?
May 02, 2018 · Advantages of PP. Polypropylene is a thermoplastic that is being used currently in many fashions. In the vast variety of applications in which PP is used, here are a few ways PP has already changed the world. The product is in global demand because it can do things other plastics can’t. For instance, PP can substitute some gears.
Polypropylene Chemical Resistance Guide
with polypropylene than polar media such as ethanol and acetone. Some reduction in tensile strength and an increase in ˛exibility and elongation-to-break in tension can be expected, depending on the nature and amount of the organic medium absorbed. HMC PP resins have excellent resistance to environmental stress-cracking. When
Engineering and Microstructural Properties of Fiber
Aug 08, 2018 · The concrete industry is a remarkable point source of carbon dioxide emission due to the disintegration of raw materials and burning of fuel during the cement manufacturing process. One efficient way to minimize such detrimental environmental effects is utilizing waste and byproduct materials as cement replacements in concrete.
2020-04-15 · To eliminate the environmental crazing and cracking, many methods like surface coating, stress reduction are adopted. However, due to the complicity of the environmental effects, especially the effects in organic environment, it's hard to find a general solution and remove the effect completely.
