BES~Hempcrete_Press.indd 1 2016-04-29 2:52 PM Chris Magwood has combined his deep understanding of building science with some fortuitous hands-on experience of working with hempcrete to craft this timely and detailed guide to the essentials of hempcrete construction. By simply mixing the lightweight core of hemp stalks (an agricultural byproduct) with lime it is possible to make an insulating material that can handle moisture without decomposing, has good structural qualities and thermal performance, is nontoxic and fire resistant, naturally sequesters carbon, and is ultimately completely recyclable. With the successful use of hempcrete in Europe for over a decade, hopefully this book will help usher in a new era of industrial hemp production in North America. —Kelly Hart, www.greenhomebuilding.com Chris Magwood’s easy-to-read, thoughtful, and practical book on building with hempcrete is a must-have for my work as a designer and builder focused on resilient, natural, and low carbon construction. In a world increasingly threatened by climate change, practical solutions are needed now to lower our collective ecological impact as a building trade. Essential Hempcrete Construction is a critical tool in our toolkits. —Ace McArleton, coauthor, The Natural Building Companion, and cofounder, New Frameworks Natural Design/Build LLC It’s amazing to me that, in the 21st century, we still have to educate people about the many uses for industrial hemp. With this book, Chris Magwood presents an irrefutable endorsement for hemp. It’s simple common sense for building a better future—literally! —Dan Skye, editor-in-chief, High Times magazine. Essential Hempcrete Construction provides an excellent pathway towards creating buildings that are more ecologically sound, healthful, and beautiful. This guide is amazingly comprehensive – materials, techniques, costs, building science, illustrations, recipes, pros and cons and more – yet concise and readable.

The subject of Foundations although treated of in various works on construction has not heretofore, with the exception of one or two small manuals, been made the subject of a special book. The importance of the subject and the liberal patronage afforded the first edition of this work had led the publisher to believe a second edition thoroughly revised and brought down to the present date would prove valuable to those engaged in designing and constructing large and important structures. After consultation with the author it was decided to re- cast the whole thing and make it practically a new work.

CHARACTERIZATION AND RESTORATION OF HISTORIC ROSENDALE CEMENT MORTARS FOR THE PURPOSE OF RESTORATION A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Materials Science and Engineering by Stephanie Anne Hart December 2012 Accepted by: Dr. Denis Brosnan, Committee Chair Dr. John Sanders Dr. Kathleen Richardson ABSTRACT Mortar was a very common building material in today’s historic sites. Before Portland cement was manufactured at a global level, Rosendale cement was commonly used in these mortars. Over time, these mortars in historic sites have begun to break down and wear away. With Rosendale cement in production again, measures can be taken to restore and repair the historic mortars. However, little testing has been done to establish durability of modern Rosendale cement mortars. This presentation highlights the common mix techniques used at the time, and undergoes experiments to establish general properties and predict future durability.

  • Glossary of Terms
    Glossaryof terms by: JoAnn Cassar and Roberta de Angelis and John F. Gleeson Abacus: the top moulding of a capital, derived from the Greek ëabaxí. Abrasive - Hard, fine particles used to polish metals, stone, wood, glass and other materials. Naturally occurring materials used as abrasives include diamond, emery, corundum, sand, crushed garnet, quartz, pumice, diatomite, kaolin, fuller's earth, talc, chalk and cuttlefish bone. Manufactured materials used as abrasives include silicon carbide, aluminium oxide, zirconium oxide, titanium dioxide, green rouge (chromic oxide), tin oxide, cerium oxide, glass, boron carbide, boron nitride and diamond. Abrasives are sold as powders, slurries and as abrasive clothes, papers and wheels. They are characterised by hardness and particle size. Their hardness can be measured on the Mohs scale in which the diamond is rated as a 10. Mild abrasives, such as chalk and talc, have a hardness of 1-2 Mohs. Diamond and silicon carbide are hard abrasives. Particle size depends on the mesh of the sieves used for separation, i.e. a 600 grit abrasive contains particles 8 micrometers and smaller. Synonyms: diamond; emery; corundum; sand; garnet; quartz; pumice; diatomite; kaolin; fuller's earth; talc; chalk; cuttlefish bone; silicon carbide; aluminium oxide; zirconium oxide; titanium dioxide; green rouge; chromic oxide; tin oxide; cerium oxide; glass; boron carbide; boron nitride; steel wool; abrasive paper; lubrisil, micromesh; abrasive powder; crocus powder; jewellers rouge; rottenstone; tripoli powder; whiting.
