ASTM C279 – Standard Specification for Chemical-Resistant Masonry Units

Description:

Abstract

This specification covers chemical-resistant masonry units, specifically, solid kiln fired bricks and tiles made from clay, shale, or mixtures thereof, suitable for indoor and outdoor use in masonry construction subjected to chemical environments. The bricks and tiles are considered to be of three types as follows: Type I, for use where low absorption and high acid resistance are not major factors; Type II, for use where lower absorption and higher acid resistance are required; and Type III, for use where minimum absorption and maximum acid resistance are required. The masonry units shall undergo tests and adhere accordingly to the following physical and chemical requirements: water absorption, warpage, surface texture, size and dimension, flexural strength, modulus of rupture, sulfuric acid solubility, and percent weight loss.

Scope

1.1 This specification covers solid, kiln fired brick and tile made from clay, shale, or mixtures thereof, suitable for indoor and outdoor use in masonry construction subjected to chemical environments.

1.2 The brick and tile covered herein are intended for use in chemical environments where resistance to thermal shock may be a consideration. The brick and tile are normally used with chemical-resistant mortars.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
