horizontal courses
Classification of stone works - answer-Ashlar and rubble
Rubble Stone - answer-Generally consists of irregular stones with good face for the wall
surface
Alternate course ashlar - answer-When the installation of masonry blocks were
arranged in alternate thin and thick courses.
Broken Ashlar - answer-If stone of various sizes are used to course that are not
continuous for the whole lenght of wall
course rubble - answer-Is made with roughly squared blocks leveld tp 30-40cm thick
courses
bricks - answer-Are manufactured from clay and other materials processed into
workable consistency molded to sizes and fired in kiln
common brick - answer-Are made from clay called ordinarry commercial bricks
Face bricks - answer-Are made from clay used on exposed exterior and interior
masonry walls
Calcium silicate bricks - answer-Made from clay or non-clay materials with alumina and
silica used in furnance construction
Two major kind of non-clay refractory bricks - answer-Magnesia brick and chrome brick
Bond - answer-Is the term used with respect to the arrangement of bricks
Stretcher - answer-Is the term used when the bricks are laid with its longer side
exposed to view.
Header - answer-Is the term applied when the bricks are laid with its end exposed.
concrete hollow blocks - answer-It is the most widely used masonry materials for all
types of contruction such as wall, partitions, dividers, fences etc.
, Hydraulic cement - answer-Is a bonding agent that reacts with water to form a hard
stone-like substance that is resistant to disintegration in water

Magnesium flourosilicate - answer-It hardens the surface of concrete by chemical action
and make it more impervious to chemical attack
