Tezontle (Spanish: tezontle) is a porous, extrusive, igneous, volcanic rock used extensively in construction in Mexico. It is usually reddish in color.[1][2]

Composition[edit]

Chemically, tezontle is an iron oxide.[2]

Uses[edit]

Tezontle can be mixed with concrete to form lightweight concrete blocks,[3] or mixed with cement to create stucco finishes.[1] Tezontle is often used as the top layer of gravel on unpaved roads in Mexico. Many colonial buildings in Mexico use the reddish cut tezontle on their facades.

Facades[edit]

Many buildings use tezontle to create an aesthetic facade. Here are some examples.
