At a coal price of 61 per ton (for bituminous coal), the energy cost for the conventional process is ∼28 per ton of cement, which is 25% of the average US cement selling price of 113 per metric ton . The corresponding cost for the electrochemical process naturally depends on the price of electricity and could in some instances be zero or even negative if obtained from renewable resources.

process is called corrosion. For corrosion to occur, four elements must be present: There must be at least two metals (or two locations on a single metal) at different energy levels, an electrolyte, and a metallic connection. In reinforced concrete, the rebar may have many separate areas at different energy levels. Concrete acts as the electrolyte, and the metallic

Sustainability and Precast Concrete

Sustainability and Precast Concrete

Is precast concrete energyefficient? The thermal mass of precast concrete absorbs and releases heat slowly, shifting air conditioning and heating loads to allow smaller, more efficient heating, ventilating, and air conditioning (HVAC) systems.

A Study on the Crack Propagation Process in Concrete ...

The mechanical performance of concrete structures closely relates to the propagation of cracks. Depth studying energy dissipation of concrete in fracture process zone not only contributes to comprehensive understanding fracture failure mechanism of concrete, but also has significant in detecting and forecasting the cracks in actual structure.

Large amounts of energy are required to produce cement. It takes about 200 kg of coal to produce one tonne of cement and about 300400 kg of cement is needed to produce one cubic metre of concrete. Coal combustion products (CCPs), such as Fly Ash also play an important role in cement manufacture and in the construction industry generally.
