Concrete structures are susceptible to cracking, which can compromise their integrity and durability. Repairing them with ordinary Portland cement (OPC) paste causes shrinkage cracks to appear in the ...repaired surface. Alkali-activated binders offer a promising solution for repairing such cracks. This study aims to develop an alkali-activated paste (AAP) and investigate its effectiveness in repairing concrete cracks. AAPs, featuring varying percentages (0.5%, 0.75%, 1%, 1.25%, 1.5%, and 1.75%) of polyethylene (PE) fibers, are found to exhibit characteristics such as strain hardening, multiple plane cracking in tension and flexure tests, and stress-strain softening in compression tests. AAP without PE fibers experienced catastrophic failure in tension and flexure, preventing the determination of its stress-strain relationship. Notably, AAPs with 1.25% PE fibers demonstrated the highest tensile and flexural strength, exceeding that of 0.5% PE fiber reinforced AAP by 100% in tension and 70% in flexure. While 1% PE fibers resulted in the highest compressive strength, surpassing AAP without fibers by 17%. To evaluate the repair performance of AAP, OPC cubes were cast with pre-formed cracks. These cracks were induced by placing steel plates during casting and were designed to be full and half-length with widths of 1.5 mm and 3 mm. AAP both with and without PE fibers led to a substantial improvement in compressive strength, reducing the initial strength loss of 30%-50% before repair to a diminished range of 2%-20% post-repair. The impact of PE fiber content on the compressive strength of repaired OPC cube is marginal, providing more flexibility in using AAP with any fiber percentage while still achieving effective concrete crack repair. Considering economic and environmental factors, along with observed mechanical enhancements, AAPs show promising potential for widespread use in concrete repair and related applications, contributing valuable insights to the field of sustainable construction materials.
The mechanisms by which buildings and infrastructures degrade are complex, as are the procedures and methods for inspection and for rehabilitation. This book examines the various problems caused by ...non-uniform deformation changes, poor durability, and natural and human disasters such as earthquakes and fire. It explores the causes and mechanisms of deterioration and introduces general procedures and commonly used techniques for inspection and evaluation of existing infrastructures. The book examines conventional renovation techniques, compatibility between repair materials and degraded materials, and fibrous composite materials. It also discusses fibrous composite strengthening techniques for beam, wall, column and slabs along with codes of practice for retrofitting with fibrous composites.

The United States military stores more than 4,000 aircraft in the Arizona desert at the 309th Aerospace Maintenance and Regeneration Group (AMARG) facility adjacent to Davis-Monthan Air Force Base. ...Known as the "Boneyard," this facility is much more than a place where aerospace vehicles come to die. Here some aircraft are maintained in both short- and long-term storage, while others serve as a "parts inventory on the wing" holding valuable spare parts in known locations ready to be harvested, overhauled, and returned to the fleet when needed. When an aircraft has yielded all the parts necessary to keep its brethren in the air, its carcass eventually meets the scrapper's torch. AMARG's storage rows are home to massive fleets of F-15, F-16, and F/A-18 fighters, aerial refuelling tankers, C-130 and C-5 transports, helicopters of varying sizes, and bombers from the frontline B-1 to B-52s that are much older than the pilots flying them around the globe today. Among the rows are special use aircraft including the AWACS, P-3 maritime patrol bombers, aeromedical evacuation aircraft, and reconnaissance planes that serve a variety of missions, along with celebrity aircraft such as MiG killers that dominated the skies in aerial combat. As well as bringing the reader up to date with recent activities at AMARG, including the intake of new aircraft types, regeneration and the return to the fleet of aircraft formerly in storage, this book presents new, never-before-seen images that provide a visual tour of the Boneyard.
This is a story of how work gets done. It is also a study of how field service technicians talk about their work and how that talk is instrumental in their success. In his innovative ethnography, ...Julian E. Orr studies the people who repair photocopiers and shares vignettes from their daily lives. He characterizes their work as a continuous highly skilled improvisation within a triangular relationship of technician, customer, and machine. The work technicians do encompasses elements not contained in the official definition of the job yet vital to its success. Orr's analysis of the way repair people talk about their work reveals that talk is, in fact, a crucial dimension of their practice. Diagnosis happens through a narrative process, the creation of a coherent description of the troubled machine. The descriptions become the basis for technicians' discourse about their experience, and the circulation of stories among the technicians is the principal means by which they stay informed of the developing subtleties of machine behavior. Orr demonstrates that technical knowledge is a socially distributed resource stored and diffused primarily through an oral culture. Based on participant observation with copier repair technicians in the field and strengthened by Orr's own years as a technician, this book explodes numerous myths about technicians and suggests how technical work differs from other kinds of employment.
Process machines are critical to the profitability of processes. Safe, efficient and reliable machines are required to maintain dependable manufacturing processes that can create saleable, on-spec ...product on time, and at the desired production rate. As the wards of process machinery, we wish to keep our equipment in serviceable condition. One of the most challenging aspects of a machinery professional or operator's job is deciding whether an operating machine should be shut down due to a perceived problem or be allowed to keep operating. If he or she wrongly recommends a repair be conducted, the remaining useful machine life is wasted, but if he or she is right, they can save the organization from severe consequences, such as product releases, fires, costly secondary machine damage, etc. This economic balancing act is at the heart of all machinery assessments.
