ASTM C412-2019 pdf free download.Standard Specification for Concrete Drain Tile
1. Scope
1.1 This specification covers concrete drain tile with inter- nal diameters from 4 to 36 in. that are intended to be used for surface and subsurface drainage. 1.2 A complete metric companion to Specification C412 has been developed—C412M; therefore, no metric equivalents are presented in this specification. N OTE 1—This specification is a manufacturing and purchase specifica- tion only and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of drain tile. However, experience has shown that the successful performance of the product depends upon the proper selection of the class of drain tile, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner is cautioned that he must correlate the field requirements with the class of drain tile specified and provide for or require inspection at the construction site. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Classification
4.1 Drain tile manufactured according to this specification shall be of the following four classes: 4.1.1 Standard-Quality Concrete Drain Tile, intended for land drainage of ordinary soils where the tile are laid in trenches of moderate depths and widths. Standard-Quality concrete drain tile are not recommended for use where internal diameters in excess of 12 in. are required. 4.1.2 Extra-Quality Concrete Drain Tile, intended for land drainage of ordinary soils where the tile are laid in trenches of considerable depths or widths, or both. 4.1.3 Heavy-Duty Extra-Quality Concrete Drain Tile, in- tended for land drainage ofordinary soils where the tile are laid in trenches of large depths or widths, or both. 4.1.4 Special-Quality Concrete Drain Tile, intended for land drainage where special precautions are necessary for concrete tile laid in soils that are markedly acid or contain unusual quantities ofsulfates (see Section 7), and where the tile are laid in trenches of considerable depths or widths, or both. Where the calculated loads are in excess of the crushing strengths prescribed in the physical requirements for extra-quality and special-quality concrete drain tile, tile strengths must be specified in advance by the owner.
5. Basis of Acceptance
5.1 The acceptability ofdrain tile shall be determined by (1) the results of the physical tests as specified in Section 8, and in Test Methods C497, (2) measurements and inspection to ascertain whether the tile conform to the requirements regard- ing dimensions, shape, and freedom from visible defects, and (3) the manufacturer’s certification in writing that the tile have been made in accordance with any special provisions, such as strength, absorption, permeability, type of cement, admixture, curing conditions, etc. 5.2 The owner shall specify in writing the class or classes of concrete tile to be supplied, whether Standard-Quality, Extra- Quality, Heavy-Duty Extra-Quality, or Special-Quality. Unless Extra-Quality, Heavy-Duty Extra-Quality, or Special-Quality concrete drain tile have been specified, Standard-Quality drain tile shall be accepted.
6. Materials
6.1 Concrete—The concrete shall consist of cementitious materials, mineral aggregates, admixtures, if used, and water. 6.2 Cementitious Materials: 6.2.1 Cement—Cement shall conform to the requirements for portland cement of Specification C150/C150M, or shall be portland blast-furnace slag cement, portland-limestone cement, or portland-pozzolan cement conforming to the requirements of Specification C595/C595M, except that the pozzolan con- stituent in the Type IP portland-pozzolan cement shall be fly ash. 6.2.2 Fly Ash—Fly ash shall conform to the requirements of Specification C618, Class F or Class C. 6.2.3 Slag Cement—Slag cement shall conform to the re- quirements ofGrade 100 or 120 ofSpecification C989/C989M. 6.2.4 Allowable Combinations ofCementitious Materials— The combination ofcementitious materials used in the concrete shall be one of the following: Portland cement only, Portland blast-furnace slag cement only, Portland-pozzolan cement only, Portland-limestone cement only, A combination of portland cement or portland- limestone cement and fly ash.
