SAND-FACED PLASTER

PLASTERING
Plastering provides a finished surface that is firm and smooth.
The plaster acts as a sound and thermal insulation layer to some extent.
Plaster is a layer of cement-sand mortar applied over a masonry work which also acts as a damp-proof coat over the masonry.
Plastering enhances the appearing of the building.
Helps to provide a suitable base for colour wash.

SAND-FACED PLASTER
The first coat of cement plaster is carried out in cement mortar of proportion 1:4,I.e. one part of cement to four parts of clean,coarse and angular river sand by volume.
The thickness of first coat is 12mm.
The first coat is to be well watered for atleast 7 days.
The first coat is provided with zigzag lines so that the first coat adheres well with the second coat.
The second coat of sand-faced cement plaster is carried out in proportion 1:3 and the thickness of second coat is 8mm.
The second coat should be applied on the first coat before 7 days of completion of first coat.
Sand to be used in the mortar for the second coat is to be perfectly screened so that sand of uniform size appears on the surface.
Sponge is used on the second coat and it is applied when the second coat is wet and it is so worked that the density of sand grains appearing on the surface is equal and uniform.
After completion of the second coat, the surface is kept well-watered at least for 15 days.

DEFECTS IN PLASTERING
Blistering or plastered surface
Cracks
Flaking
Peeling
Popping rust-stains
Softness
Uneven surface

FOR MINIMISING DEFECTS IN PLASTERING WORK

The brick and plastering work should be carried out by skilled masons in the best workmanship manner.
Bond of brick should be properly maintained.
The surface to be plastered should be well-watered so that it may not absorb water from plaster.
Excessive trowelling should be avoided.
Fresh plaster surfaces should be protected from rain,dirt and excessive heat as sun.
Water free from salts should be used for brick work and plastering work.

CONTEMPORARY CITY FOR THREE MILLION INHABITANTS

Urban design by Le Corbusier, 1922 Exhibited in 1922 at the Salon d’Automne in Paris, the Contem-porary City for Three Million Inhabitants was Le Corbusier’s first comprehensive urban-planning project. Accompanied by a 100-square-meter diorama, it consisted of a rigidly geometric, centralized orthogonal plan with monumental axes, uniform modern buildings, vast expanses of open space covering 85 to 95 percent of the surface, and a system of highways. The project was seen simultaneously as a breathtaking modern vision and as the destruction of the familiar urban setting. Influence on the project ranged from American gridded cities, Peter Behrens’ work, and Tony Garnier’s Une Cité industrielle (1901–04, 1917; An Industrial Town) to Bruno Taut’s Utopian Die Stadtkrone (1919; The City Crown). By 1922 Le Corbusier was one of the major figures of the Modern movement, and the Contemporary City marked a high point in a period of extraordinary activity. It incorporated two ideas that he had been...

DOM-INO HOUSES

Housing design by Le Corbusier, 1914–15 and later Between 1914 and 1915, Le Corbusier, partly encouraged by his friend Max du Bois, conceived of a standardized system of construction using reinforced concrete, which was to provide the structural basis of most of his houses through the mid-1930s. These were the Dom-ino prefabricated houses with independent skeletons. The frame was to be completely independent of the floor plans of the houses. Derived from the Hennebique frame, it consisted of six thin concrete columns that simply carried two horizontal slabs as the floors. The columns and slabs were connected by staircases. Apart from this structural core of the houses, nothing else was fixed, thus permitting a great flexibility to suit demands on the basis of aesthetics, climate, composition, or view. The floor plan was also extremely flexible, as interior partitions were independent of the grid. This utterly simple and clear “open plan” method did away with load-carrying walls. Suppor...
