Driving Energy Efficiency in Heavy Industries

Mar 17, 2021In the process of concrete curing, some portion of cement does not come in contact with water and is left unhydrated (some estimates suggest that up to 50% of cement could remain unhydrated). New concrete crushing technologies are under development that would enable recovering this unhydrated cement from end-of-life concrete for direct reuse as

Environmental Guidelines for Cement Manufacturing

335 Cement Manufacturing Air Emissions Ambient Noise A maximum emissions level of 50 milligrams per normal cubic meter (mg/Nm3) (equivalent to a maximum of 0.2 kg/t of clinker) for particulates in stack gases under full load conditions is to be achieved. This emission level is based on values that are routinely achieved in well-run plants.
