Detailed introduction

Wood ash as a cement replacement reduces CO2 .The production of cement is currently estimated to amount for five percent of global CO2 emissions. A forecast from the Danish Technological Institute predicts that the demand for cement will be doubled in 2050 compared to the need in 2010.Co-processing: Addressing the nation's waste .In a single combined operation in the kiln or the main cement production chamber, co-processing completely destroys the qualified waste-turned-fuel at optimal temperatures of 1,450 degrees Celsius. Any waste byproducts such as ash are fully integrated into the microstructures of the clinker, a key ingredient of cement.Balance emissions and CO2 uptake in concrete structures: .In cement life cycle, 95% of total CO 2 emitted comes from the production stage [], with almost the entire emission in cement industry concentrating on the clinker production [], since during the cement production process, half of the emitted CO 2 is caused by the calcination of limestone rock, and the other half derives from the burning of fuels for energy generation in the clinkering process [].
