  • The Art of Stone Masonry in the Rockbridge County Area (1700 to Present)
    The Art of Stone Masonry In the Rockbridge County Area (1700 to present) Steven Connett Archaeology 377 5/25/83 Dr. McDaniel The art of stone masonry in the Shenandoah valley seems to be somewhat of a mystery prior to the nineteenth century. However, as some of us have learned from the anthropology 101 course: The absence of artifacts (documents in this case) is just as important as the presence of artifacts. In order to make sure that the lack of information was not due to my possible incompetence in research, I spoke with a current day stone masoner named Alvis Reynolds. Mr. Reynolds relayed t o me that when he was trying to learn the skills of stone masonry he, too, had great difficulty in obtaining information and thus decided to teach himself this art through the process of trial and error. Although this information did not directly aid me in my research, Mr. Reynolds did provide me with a bit of information that allowed me to derive a hypothesis on why there is this unusual lack of information in this line of study. I will state my hypothesis in this paper, however, I will not be able to prove it or disprove it due to the deficiency in available information. Mr. Reynolds explained to me that in the eighteenth century there were nomadic stone masoners. These nomadic workers went from valley to valley in search of people who needed help with building their houses. Since these people did not know how to cut stone themselves (after all, stone cutting is not the type of thing that is innate to most people) they had no choice but to p~y these men for their services or go unsheltered.

    %:% : LIFE SIR WILLIAM E. LOGAN, It., LL.D., F.E.S., F.G-.S., &c. first director of the geological survey of canada. Chiefly Compiled feom his Letters, Journals and Reports. BERNARD J. HARRINGTON, B.A., Ph.D., PROFESSOR 01' MINING IN M'GILL UNIVERSITY ; LATE CHEMIST AND MINERALOGIST TO THE GEOLOGICAL SURVEY OP CANADA. WITH. STEEL PORTRAIT AND NUMEROUS WOODCUTS. EonBon SAMPSON LOW, MARSTON, SEARLE, & RIVINGTON, CROWN BUILDINGS, 188 FLEET STREET. 1883 6 PREFACE. rPHE task of preparing a biography of Sir William Logan was not a self-imposed one, and was only undertaken with feelings of great delicacy. There are those who knew him longer and more intimately, and who might have done far better justice to his memory. But the work having been entrusted to me, I have endeavoured to discharge it faithfully. My aim has not been to write a eulogium or yet a lengthy criti- cism of Sir William, but rather to bring together such of his own words as will recall him to the minds and hearts of old friends, or enable those who were not privileged with his acquaintance to form for them- selves an estimate of his character and work. Canadians cannot afford to forget the name of oije who laboured so long and so earnestly to promote the interests of this his native land, and if the following pages in any way serve to keep green the memory of Sir William Logan, their compiler will feel more than repaid. We have plenty of Canadians able and willing vi. PREFACE. to work for themselves, but too few who, like Logan, are willing to work for Canada.

  • Concrete Repair
    CONCRETE REPAIR CONCRETE REPAIR TERMINOLOGY Abrasion — Surface wear that causes progressive loss of material from a concrete surface. caused by rubbing and friction against the surface by machinery, Forklift traffic or dragging of materials across slab. Abrasive—any hard, strong substance, such as rocks, sand, water, or minerals, that will cut, scour, pit, erode, or polish another substance. Absorption—the process by which a liquid is drawn into and tends to fill permeable voids in a porous solid body; also, the increase in mass of a porous solid body resulting from the penetration of a liquid into its permeable voids. Acid Etching—application of acid to clean or alter a concrete surface; typically used only when no alternative means of surface preparation can be used. Acrylic Resin— acrylic. activator—a material that acts a catalyst. Created to provide both bonding powers and a hard layer of protection Additive—a substance added to another in relatively small amounts to impart or improve desirable properties or suppress undesirable properties; any material other than the basic components of a grout system. Adhesion—a state in which two surfaces are held together through interfacial effects that may consist of molecular forces, interlocking action, or both. Adhesive Failure— A bond separation between an adhesive and the material bonded to. ( See Cohesive failure ) Admixture—a material other than water, aggregates, hydraulic cement, or fiber reinforcement, added to concrete, mortar, or grout, during batching or mixing to enhance plastic or hardened material properties, or both. Accelerating—an admixture that (1) increases the rate of hydration of the hydraulic cement and thus shortens the time of setting, increases the rate of strength development, or both; (2) any substance that increases the rate of a chemical reaction.

A guide to analysis discusses development, structure, and validation method; scope of the occupation; trends; and safety. To facilitate understanding the nature of the occupation, work performed is divided into these categories:(1) blocks, the largest divisions in the analysis that reflect distinct operations relevant to the occupation;(2) tasks, the distinct activities that in combination make up the logical and necessary steps the worker is required to perform to complete a specific assignment in a block; and (3) sub-tasks, the smallest divisions into which it is practical to subdivide any work activity and which, in combination, fully describe all duties constituting a task.
