Stone Masonry Classification Quiz

Questions and Answers

Explain the classification of stone masonry based on the arrangement of stones and the degree of refinement used in shaping the stone and finishing adopted.

Stone masonry can be classified into Rubble Masonry and Ashlar Masonry. Rubble masonry includes Random Rubble (Uncoursed and Built to courses), Square Rubble (Uncoursed, Built to courses, Regular coursed), and Miscellaneous types (Polygonal walling, Flint walling). Ashlar masonry involves more refined and precisely shaped stones.

What are the characteristics of rubble masonry? Provide examples of the types of rubble masonry.

Rubble masonry uses undressed or roughly dressed stones with wide joints due to irregular sizes. Examples of types include Random Rubble (Uncoursed and Built to courses), Square Rubble (Uncoursed, Built to courses, Regular coursed), and Miscellaneous types (Polygonal walling, Flint walling).

How do larger stones contribute to the construction of dry rubble masonry?

Larger stones are selected for quoins and jambs to give increased strength and better appearance in dry rubble masonry.

What is dry rubble masonry and what are its characteristics?

<p>Dry rubble masonry is the roughest and cheapest form of stone walling, using widely different sizes of stones. Care and ingenuity are required to arrange the stones to distribute pressure evenly and avoid long continuous vertical joints. Sound bond should be available both transversely and longitudinally.</p> Signup and view all the answers

Explain the importance of sound bond in dry rubble masonry.

<p>In dry rubble masonry, sound bond is crucial to distribute the pressure evenly and avoid long continuous vertical joints. Transverse bond is obtained by the liberal use of headers, and larger stones are selected for quoins and jambs to provide increased strength and better appearance.</p> Signup and view all the answers
