#0183;#32;Organic materials include animal and plant products; materials like wood, fiber, bark and soil are some examples. Inorganic materials are mineral products like stone, metal and composites like clay. Generally, inorganic materials contain traces of organic materials, and vice versa. Inorganic natural materials are, by definition, unprocessed.
Clay in construction Designing Buildings Wiki Share your construction industry knowledge. Clay is a finelygrained natural rock or soil material that, along with other materials such as stone and wood, has been used as for construction for thousands of years. It is composed of one or more clay minerals (such as kaolinites or smectites), sometimes with small quantities of quartz, metal
This is to help students have hands on experience in deciding what is natural or processed material, from evaluating everyday materials. By the end of this lesson students will be able to1) Define is scientific terms what Natural and Processed materials are. 2) Classify materials as Natural or Processed.

Natural material means a material which is obtained directly from the nature. You dont need to do any processing to get it. Bamboo is an example of natural material. You dont need to do any processing to get bamboo. You get it directly. On the o...
The processed materials are those that have gone through some kind of processing and that are used in the manufacture of other products. These are distinguished from both the raw material concept and the component definition. Unlike the former, its natural state has undergone some sort of modification.
Since the earliest times, humankind has had a close association with clay. From use as a building material, in pottery, for treating human digestive ailments to a multitude of industrial uses, clay is a key ingredient in the material world we live in.
Clay and ceramic are often used to describe different materials for making pottery. Clay is a type of ceramic, but not all ceramics are made of clay. Clay is a natural material that comes from the ground, and ceramics are various materials that harden when heated, including clay.

#0183;#32;Clay is one of the few organic materials, which not only contribute to green buildings but also ensure that there is zero wastage of the raw material at all. A typical Clay brick undergoes an interesting lifecycle in which it is able to end up exactly where it started from.
Expansive clay is a group of minerals we refer to as smectite that expands through absorption of water within their structure. Smectite also has many industrial applications, but creates great problems in construction because it absorbs and releases water depending on environmental conditions.
Clay is a type of finegrained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and nonplastic upon drying or firing. Most pure clay minerals are white or lightcoloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour

Processed materials are often modified from natural materials or do not occur at all in the natural environment, but have been designed and manufactured to fulfil a particular purpose. On a continuum using wood as the material, timber would be the natural material and with an increasing level of processing you would have plywood, MDF (medium density fibre board) and paper.
Many natural building techniques use clay as a primary material. Adobe, cob, cordwood, and rammed earth structures all use clay as well as building elements such as wattle and daub, clay plaster, clay render, clay floors and clay paints and ceramic building materials. Mortar in brick chimneys and stone walls has clay as an ingredient.

Wood (rattan, bamboo, bark, etc.) Natural fiber (silk, wool, cotton, flax, hemp, jute, kapok, kenaf, moss, etc.) Inorganic material Stone (flint, granite, obsidian, sandstone, sand, gems, glass, etc.) Native metal (copper, iron, gold, silver, etc.) Composites (clay, plasticine, etc.) Other natural materials.

Commercial clay is mined from highgrade sources and then further processed, usually with other additives until a desired composition is achieved. People have been making ceramic objects for almost 30,000 years, and this is obviously not how they did it.
