Alternative building materials for green construction Can Concrete Be Eco Friendly Green Living Ideas
While the world has come to rely on concrete as one of the main material for building construction concrete could actually harm the environment more than it is helping To illustrate 16 of all fossil fuel consumed every year is used to turn those raw materials into construction productsConcrete Alternativ In addition to cement substitutes there are other ways of making concrete more sustainable based on two core environmental principles—recycle and reduce These alternatives include The use of recycled aggregate materials and preparations that results in reduced amounts of concrete needed to complete the job

Manufacturing the cement kiln Understanding CementAlternative Raw Materials and Fuels HeidelbergCement Group
However new cement kilns are of the dry process type Dry process kilns In a modern works the blended raw material enters the kiln via the pre heater tower Here hot gases from the kiln and probably the cooled clinker at the far end of the kiln are used to heat the raw meal As a result the raw meal is already hot before it enters the The conservation of natural resources is part of our sustainable business strategy That is why we make greater use of waste materials and by products from other industries as valuable raw materials and fuels We use alternative raw materials for the production of clinker which is the most important intermediate product in the manufacture of cement
