4.1 The brick and tile covered herein are intended essentially for use in chemical environments where resistance to thermal shock may or may not be a consideration. The brick and tile are normally used with chemical-resistant mortars.
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.
Область применения1.1 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 (see Terminology C1232).
1.2 The physical and chemical properties of brick and tile differ from supplier to supplier, mainly because their composition is determined by the source of raw materials. Regardless of the differences, brick and tile are considered to be one of three types and one of two classes as follows:
1.2.3 Type III—For use where minimum absorption and maximum acid resistance are required.
