This paper reports the synthesis of a solidform geopolymer by ballmilling of raw materials of varying compositions together in the solid state. This resulted in the formation of readytouse geopolymeric precursors, which on 'just the addition of water' led to the development of solidform geopolymeric binder with enhanced reactivity and properties. Conventional geopolymers are ...
This is an experimental study which explores the physical, mechanical, and economic factors involved in the production of type CEM II AB/W cement. In this context, 4 cement additives were used in two different dosages (200 and 800 g/t). Class C fly ash was used for composite cement production at ratios of 5%, 20%, and 35%.
Testing is also being done to support the use of recycled supplementary cementicious materials such as Fly Ash and NewCem throughout the region while investigating the future of recycled material. Lafarge is convinced that sustained economic growth cannot occur without social progress, environmental protection and respect for local communities.

A. Fly ash is produced through the combustion of coal used to generate electricity. After coal is pulverized, it enters a boiler where flame temperatures reach up to 1500 degrees Celsius. Upon cooling, the inorganic matter transforms from a vapor state to a liquid and solid state. During this process individual, spherical particles are formed.
