Abstract
This specification establishes the types, physical properties, and dimensions of bulkhead corrugated asbestos-cement sheets designed to provide sheet piling for erosion control along fresh-water lake shores and inland waterways of fresh or salt water. The asbestos-cement sheets covered here are classified into five types (Types 1, 2, 3, 10, and 18) on the basis of the bending moment capacity of saturated units. Sheet materials shall be composed of a combination of asbestos fiber and portland cement, or portland blast furnace slag cement, and organic fiber, with or without the addition of curing agents, silica, water-repellent substances, mineral fillers, coatings, pigments, or mineral granules formed under pressure and cured to meet the physical property requirements. These physical requirements include bending moment strength, nominal dimensions (length, width, and thickness), pitch, corrugation depth, and color. Specimens shall also go through flexural strength tests, the sampling, preparation, and examination procedures for which are discussed thoroughly.
Scope
1.1 This specification covers the types, physical properties, and dimensions of bulkhead corrugated asbestos-cement sheets designed to provide sheet piling for erosion control along fresh-water lake shores and inland waterways of fresh or salt water.
1.2 The values stated in SI units are to be regarded as standard. The values stated in parentheses are provided for information only.
1.3 Warning—Breathing of asbestos dust is hazardous. Asbestos and asbestos products present demonstrated health risks for users and for those with whom they come into contact. In addition to other precautions, when working with asbestos-cement products, minimize the dust that results. For information on the safe use of chrysotile asbestos, refer to “Safe Use of Chrysotile: A Manual on Preventive and Control Measures.”2
1.4 The following precautionary caveat pertains only to the test method portion, Sections 9 – 12 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
