Masonry

Masonry may be defined as the construction of building units bonded together with mortar.The building units may be stones , bricks or precast blocks of concrete.When stones are used as the building units,we have stone masonry ,similarly , in bricks masonry , bricks are used as the building units.A composite masonry is a construction is a construction in more building crafts and one of the oldest.It has built itself great reputation as one of the premier traditional materials of the building.Even though new principles of construction and new materials become prominent in  building construction practice , masonry has got the highest  importance in building industry.
Masonry is normally used for the construction of foundations, walls. columns and other similar structural components of buildings.The basic advantage of masonry construction lies in the fact that in load bearing structure, it performs a verity of functions such as supporting loads, sub dividing space ,providing thermal and acoustic insulation , affording fires and weather protection etc..which in a framed structure has to be provided separately .Earlier , the use of masonry construction had its limitations in multistory buildings.The 16 story ' Monadnock building ' in chicago designed by John Roet 1892 has 180 cm thick brick walls at the base.However , extensive research , including large scale testing , has been carried out in regards to the behavior of masonry  which has enabled engineers to design tall masonry structure on sound engineering principles with greater exactitude , economy and confidence.
Depending upon the type of building units , masonry may be of the followings.
1- Stone Masonry       2- Brick masonry       3- Hollow concrete blocks masonry
4- Reinforced brick masonry                         5-     Composite masonry

Stone Masonry Materials

Stones The stones also used for masonry should be hard , durable , tough , and sound , free from weathering , defects like cavities , cracks , sand holes , injurious veins , patches of loose or soft materials etc. The stones should be obtained only from approved quarry.The stone should be obtained by quarrying large massive rock and not by breaking small size.Boulders having rounded faces. Rocks from which building stones are obtained , are divided into three groups : 1- Igneous rock         2- Sedimentary rocks   3-  Metamorphic rocks   1- Igneous rock It has been formed by agency of heat , the molten material subsequently become soli ified.The cheif building used in steps , facing work , walls etc.However , it is unsuitable for carving work.It is more suitable for heavy engineering works such as docks , break waters, light houses , masonry bridges and piers. 2- Sedimentary rocks  It has been formed chiefly through the agency of water.Most of these have been derived fro
