Specific gravity is the ratio of the density of a material to the density of water. The density of water is about 1 gram per cubic centimetre (g/cc). Materials which are lighter than water (specific gravity less than 1.0) will float. Most materials have specific gravities exceeding 1.0, which means they are heavier than water and so will sink. Knowing the specific gravity is important for planning spill clean-up and fire fighting procedures. For example, a light flammable liquid such as gasoline may spread and, if ignited, burn on top of a water surface. \n\nThis principle can be very vital in fire extinguishers. For example, you cannot use a water based fire extinguisher to douse a flame arising out of burning oil. The oil, on account of its lower specific gravity will simply float to the surface of the water and continue to burn. On the other hand you could use a foam based fire extinguisher which will float on the oil, cut the oxygen supply to the burning flame and extinguish it eventually. :)

considering ur trying coal or other burning material as fuel.\n\nif the ash content is more means then the heat conductivity will be less from core of the fire.\n\nash is formed due to loosely packed material and has very less heat in it.\n\nash has less sp.heat capacity.

Creation of fire\nFire is simply glowing gas and other combustion materials such as carbon particles. It is not plasma, as it is not hot enough to reach such high ionization as is required of plasma (an 'electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles').\n\nThis state of matter can be generated through focused concentrations of energy (such as fuel being exposed to an already open flame or to the Sun's rays focused through a lens), or through an exothermic chemical reaction usually accompanied by intense heat released during a rapid oxidation of combustible material(striking a match). Fire may be visible as a brilliant glow and/or flames and may produce smoke.\n\nFires start when a flammable or combustible material with an adequate supply of oxygen or another oxidizer is subjected to enough heat. The common fire-causing sources of heat include a spark, another fire (such as an explosion, a fire in the oven or fireplace, or a lit match, lighter or cigarette) and sources of intense thermal radiation (such as sunlight, a flue, an incandescent light bulb or a radiant heater). Mechanical and electrical machinery may cause fire if combustible materials used on or located near the equipment are exposed to intense heat from Joule heating, friction or exhaust gas. Fires can sustain themselves by the further release of heat energy in the process of combustion and may propagate, provided there is a continuous supply of oxygen and fuel. Fires may become uncontrolled and cause great damage to and destruction of human life, animals, plants and property.\n\nFire is extinguished when any of the elements of the so-called fire triangle—heat, oxygen, or fuel— are removed. The unburnable solid remains of a combustible material left after a fire are called ash.\n\nFlames can conduct electricity, as a small portion of any fire is ionized. This has been demonstrated in the laboratory and also in large wildfires that occur in the vicinity of power lines. This ability to conduct electricity is due to its partially plasmatic nature.

I am a ceramist.  Porcelain clay is hardened and made permanent by firing in a kiln at temperatures of between about 1200 degrees Celsius and about 1400 degrees Celsius. The toughness, strength and translucence of porcelain arises mainly from the formation at high temperatures within the clay body of the mineral mullite and GLASS.  \n\nThe side and rear car windows are made of tempered glass.  The glass is heated (at lower temperatures than required to make porcelain), then rapidly cooled. This "tempering" process makes the glass many times stronger than un-tempered glass of the same thickness.  Upon impact, tempered glass is designed to disintegrate into small pieces of glass about the size of rock salt. \n\nSince porcelain is heated at a higher temperature than auto glass, the harder porcelain will easily break auto glass.

There are many structural uses for timber in the construction industry.  It's high strength to weight properties make it an excellent material for :\njoists / beams / rafters / trusses / drywall framing etc.\nTimber (although flammable) also has the advantage of maintaining a great deal of it's strength in a fire as a carbon layer usually forms over the timber's surface resulting in the fire extinguishing.  Hence the reason we see so many burnt out buildings with charred roof members still in place.   Hope this helps.

Try the ASCE research library it has some good articles on civil engineering.\nYou will have many options to choose for example you can choose bridges

Heat distortion temperature (HDT) is determined by placing the the sample material under a defined pressure load and then exposing it to heat which is uniformly raised. The temperature at which a specified deflection occurs is the HDT.

kakani P wrote an excellent explanation but I wanted to add an example to help you furhter understand a practical application.\n\nThe tooth on the front of a backhoe bucket is a great piece to be carburized.  It could be made totally of high carbon throughout but that would make it brittle and subject to break since it experiences many impacts and shock loads as it encounters rocks (or old concrete from foundations being demolished) and other debris in the soil.  We still would like to have the surface hardened to reduce wearing but we still want the core to be ductile to prevent premature failure.  Carburizing allows us to "have our cake and eat it too".  We can make the surface wear resistent and hard but leave the core ductile and able to withstand large shock loads through the process of carburizing.

I work with epoxy composites. Epoxys have decent thermal conductivity and are strong, there are also a million different types of epoxys out there, so i'm sure theres a formula that would work for you. Good Luck

Dear mr./ms. engineer, \n\nProducing ceramics is one thing and managing the busyness is another. You should include in your question what kind of help you need.
