The purpose of this standard is to provide the minimum requirements for liquid sodium silicate, including physical, chemical, sampling, testing, packaging, and shipping requirements.
This standard describes liquid sodium silicate used in the preparation of activated silica, which is used as a coagulant aid for the treatment of potable water, wastewater, or reclaimed water and for (1) the control of corrosion and (2) stabilization of iron and manganese. It can be referenced in documents for purchasing and receiving liquid sodium silicate and can be used as a guide for testing the physical and chemical properties of liquid sodium silicate samples. The stipulations of this standard apply when this document has been referenced and then only to liquid sodium silicate used in potable water, wastewater, or reclaimed water.

This guide is intended for estimation of prestress losses in concrete structures. Methods presented include lump sum, simplified approaches addressing individual source of loss, and additional estimation methods. They address losses in pretensioned and post-tensioned members, including bonded, unbonded, and external tendons. Note that these estimation methods have not been evaluated for relative merits. A discussion of the variability of prestress losses caused by the variability in concrete properties is also presented. Several example problems are included.

This guide provides guidance on planning, performing, and documenting visual condition surveys of concrete structures. Chapter 1 defines the objective and scope of this guide and Chapter 2 covers terminology. Chapter 3 includes the process and tools one would use to plan and conduct a condition survey. Chapter 4 provides an image library and associated descriptions of the visual features that may be encountered when conducting the survey. Chapters 5 through Chapter 7 discuss the likely causes of the various features one might see when performing a visual condition survey.

This guide is intended for use by architects, engineers, contractors, building officials, and manufacturers. Its purpose is to present, in a single source, information that can help those individuals design, specify, and construct with factory-reinforced panels of autoclaved aerated concrete (AAC). In this guide, introductory information on AAC is first presented, followed by a description of its manufacture, guidance on structural design using reinforced panels, and guidance on construction with such panels. The body of this guide ends with an extensive background chapter on the material characteristics of AAC and the structural behavior and design of AAC elements.
