Material Study – Part 2

In the second part of the material study we will look towards some more materials with their properties.These materials are general though their comparison or question on their characterstics in regards to counstruction process can be asked.For Example –

So starting on with the material study the topics to be discussed are as follows –

  • Glass

Glass is a non-crystalline amorphous solid material produced by cooling of viscous molten material.It comprises of Sodium carbonate,silica, manganese dioxide,lime, boron oxide.

It is most typically used as transparent glazing material in the building envelope, including windows in the external walls.When used in buildings, glass is often of a safety type, which include reinforced, toughened and laminated glasses.It is a reflective material and reflects light and sound upto a certain extent.

  • Paint 

Paint is any liquid or liquefiable composition that is applied over any material like brick, steel, wood. It varnishes the surface and gives it a decorative feel along with protecting it from seasoning or any other damage.

Components of Paint –

  1. Pigment and filler – Pigments are granular solids incorporated in the paint to contribute color. Fillers are granular solids incorporate to impart toughness, texture, give the paint special properties, or to reduce the cost of the paint.
  2. Diluent or solvent or thinner – The main purposes of the diluent are to dissolve the polymer and adjust the viscosity of the paint.
  3. Binder or Film former – The binder is the film-forming component of paint.

Types of Paint –

  1. Primer – is a preparatory coating put on materials before applying the paint itself.
  2. Oil Paint – it is a slow drying paint with particles suspended in drying oil. 
  3. Emulsion paints– are water-based paints in which the paint material is dispersed in a liquid that consists mainly of water.
  4. Distemper–  Distemper is a water based paint which is a combination of components like powdered chalk, lime.
  • Wood

.Wood has been an important construction material since humans began building shelters, houses and boats. Since wood is hydroscopic (it acquires and loses moisture from the ambient conditions around it) this potential instability effectively limits the length and width of the boards.

Types of Wood 

  1. Arjun
  2. Babul
  3. Bamboo
  4. Banyan
  5. Coconut
  6. Deodar
  7. Mahogany
  8. Sal
  9. Sandalwood
  10. Teak,etc
  • Stone

Stone is a naturally occurring substance, a solid aggregate of one or more minerals. Stone is seldom used in building construction.

Different types of stones –

Igneous Rocks 

  1. Granite  Granite  is  an  igneous  rock,  ordinarily  composed  of  feldspar,  mica,  and  silica  or  quartz.

Sedimentary Rocks

  1. Sandstone- Sandstone consists of fragments of other rocks cemented together. The  colours  of  sandstone  are  white,  cream,  yellow,  dark  brown,  blue,  and  red.
  2. Limestone- All  limestones  are  of  sedimentary  origin  and  have  for  their  principal  ingredient  carbonate  of  lime.

Metamorphic Rocks 

  1. Marble-Metamorphosed limestone gives the masonry material known as marble.  It  is  easily  dressed  to  a  smooth  surface  and  polished,  and  is  considered  one  of  the  most  valuable  building  materials.
  2. Slate-Slate is a laminated rock of great hardness and density.  It splits readily along planes called planes of slaty cleavage.  This  facility  of  cleavage  is  one  of  the  most  valuable  characteristics  of  slate,  as  masses  can  be  split  into  slabs  and  plates  of  small  thickness  and  great  area.
