MASONRY WORKS
In ancient times, skilled masons erected stone buildings and complex engineering works (towers, arched bridges, and domes); however, the masonry work was done slowly, and the methods changed little over the centuries. Masonry work was done by hand; the master masons usually performed all the preparatory and transport jobs at the site and prepared the mortar and delivered it to the work area themselves. In building walls, cumbersome scaffolding was erected to their full height. The work was done only in the warm seasons. In the early 20th century, measures were taken in the developed countries to improve masonry work (mechanization of the delivery of materials and the preparation of mortar).
