ASTM C1492

This specification deals with the standards for concrete tiles intended for use as roof covering where durability and appearance are required to provide a weather-resistant surface of specified design. The tiles are manufacture from cement, water, and mineral aggregates and shaped during manufacturing by molding, pressing, or extrustion. The tiles may or may not contain inclusion of other materials. The tiles shall also be tested for the following requirements: dimensional tolerance, freeze thaw, transverse strength, permeability, and water absorption.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers concrete tiles intended for the use as roof covering where durability and appearance are required to provide a weather-resistant surface of specified design.

1.2 Tiles are manufactured from portland cement, water, and mineral aggregates with or without the inclusion of other materials.

1.3 Tiles are shaped during manufacturing by molding, pressing, or extrusion. The shaping method can be used to describe the tile.

1.4 Other constituents, such as chemical and mineral admixtures established as suitable for use in concrete, shall conform to ASTM standard specifications where applicable, or shall be shown by tests or experience not to be detrimental to the durability of concrete.

1.5 Tiles are generally planar or undulating rectangular shapes available in a variety of cross-sectional areas profiles, shapes, sizes, surface textures, and colors.

Note 1—Concrete roof tiles covered by this specification are made from lightweight or normal weight aggregates, or both.

Note 2—When particular features are desired, such as color, surface texture for appearance, or other special features, such properties should be specified by the purchaser. However. the local sellers should be consulted as to the availability of concrete roof tile having a desired feature.

1.6 The values stated in inch-pound units are to be regarded as the standard.
