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

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.

Geopolymer Concrete
Geopolymer concrete an innovative material that is characterized by long chains
or networks of inorganic molecules is a potential alternative to conventional portland
cement concrete for use in transportation infrastructure construction. It relies
on minimally processed natural materials or industrial byproducts to significantly
reduce its carbon footprint, while also being very resistant to many of the durability
issues that can plague conventional concrete. However, the development of this
material is still in its ....etc

Geopolymer cement is often mixed up with alkali-activated slag developed since 1956 in Eastern Europe by G.V. Glukhovsky. Alkali-activation, which is generally performed with corrosive chemicals (see below User-friendly), is used for the making of concretes exclusively. The alkali-activated materials are not manufactured separately and not sold to third parties as commercial cements. On the opposite, geopolymer technology was from the start aimed at manufacturing binders and cements for various types of applications.
In this section we are dev ....etc

STUDY ON DURABILITY OF FLYASH CONCRETE



INTRODUCTION

Fly ash is a byproduct of coal burning power plants - the ash that flies up their
smokestacks and gets captured in giant filters. It can be used to produce stronger, more
durable and more environmentally friendly concrete. When used in concrete, fly ash acts like
cement, and actually replaces a percentage of the Portland cement normally used. Concrete
with high percentages of fly ash looks and finishes the same as regular c ....etc

The cement industry is the India s second highest payer of Central Excise and Major contributor to GDP. With infrastructure development growing and the housing sector booming, the demand for cement is also bound to increase. However, the cement industry is extremely energy intensive. After aluminium and steel, the manufacturing of Portland cement is the most energy intensive process as it consumes 4GJ per tonne of energy. After thermal power plants and the iron and steel sector, the Indian cement industry is the third largest user of coal in t ....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
