[16] [17] As stone does not change size like fired clay bricks, brick-sized stone ashlars do not require expansion joints. Cyclopean concrete . This method uses a combination of cyclopean masonry and rubble masonry : boulders and or rubble are placed in a form (or in a ditch), and concrete is poured on top to bind the stones together before ...
Short forms, up to 60 cm high, are placed on both sides of the wall to serve as a guide for the stone work. The stones are placed inside the forms with the good faces against the form work. Concrete is poured in behind the rocks. Rebar is added for strength, to make a wall that is approximately half reinforced concrete and half stonework. The ...

Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are ...
By doubling the size of the arch, Paul Séjourné paved the way for the construction of large reinforced concrete arch bridges. The arrival of new construction techniques using steel, such as suspension bridges, prestressed concrete bridges, or cable-stayed bridges, abruptly marked the end of masonry bridge construction in the Western world.
A keystone (or capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight.
In Belize, the Mayan ruins at Lubaantun illustrate use of dry stone construction in architecture of the 8th and 9th centuries AD. [10] Great Zimbabwe in Zimbabwe, Africa, is an acropolis-like large city complex constructed in dry stone from the 11th to the 15th centuries AD. [11] It is the largest of structures of similar construction ...
Coursed masonry construction arranges units in regular courses. Oppositely, coursed rubble masonry construction uses random uncut units, infilled with mortar or smaller stones. [1] If a course is the horizontal arrangement, then a wythe is a continuous vertical section of masonry [2] one unit in thickness. A wythe may be independent of, or ...
For a brick structure, the panel should not be any bigger than 3' x 3'. For other masonry units, the test panel can be a little larger. It is also important to pick the right season to do the repointing. Extremely high or low temperatures can cause rapid drying which can have negative effects on the mortar, masonry units, and the structure ...
