ABSTRACT
Combustion chamber deposits are found in all internal combustion engines. When fuel and air burn inside an internal combustion engine, deposits form on the walls inside the cylinder. The factors influencing deposit formation are changes in fuel composition, coolant temperatures, engine speed and load, and spark timing. One way to discourage deposit formation is to prevent condensation. Raising the wall temperature prevent condensation. With increased wall temperature, hydrocarbon condensation te ....etc

Geopolymer Concrete:

Geopolymer was the name given by Daidovits in 1978 to materials which are characterized by chains or networks or inorganic molecules. Geopolymer cement concrete is made from utilization of waste materials such as fly ash and ground granulated blast furnace slag(GGBS). Fly ash is the waste product generated from thermal power plant and ground granulate blast furnace slag is generated as waste material in steel plant.

Both fly ash and GGBS are processed by appropriate technology and used for concrete works in the form o ....etc

Geopolymers are inorganic, typically ceramic, materials that form long-range, covalently bonded, non-crystalline (amorphous) networks . Obsidian is an example of naturally-occurring geopolymer. Commercially produced geopolymers may be used for fire- and heat-resistant coatings and adhesives, medicinal applications, high-temperature ceramics, new binders for fire-resistant fiber composites, toxic and radioactive waste encapsulation and as cementing components to make concrete. The properties and uses of geopolymers are being exp ....etc

GEO POLYMER CONCRETE-Concrete without cement


What s wrong with cement concrete?
Many concrete structures deteriorate after 20 years.

Cement production releases high amounts of CO2 to the atmosphere(1tonne of cement production releases 1tonne of CO2) thus contributing to 7% of world CO2 emissions.

Cement is one of the most energy intensive material.


How to reduce the use of cement
Partially replace the use of cement in concrete.
example: high volume fly ash concrete

Develop alternate mater ....etc

I m Surya doing my final year in civil engineering. I have chosen to work on fiber reinforced Geo polymer concrete for my final year BE project. I would like to know the tests to be performed to assess the properties , instruments required and feasibility of the project. I'd be much obliged if someone could help me.
