Green Innovations Transforming Concrete and Cement ...

Jan 08, 2021  2. Geopolymer Concrete. Australian researchers found in a study that geopolymer concrete can replace 50% of traditional concrete in use. Geopolymer concrete is an alternative that doesn’t use limestone. Instead, this concrete uses things like fly ash, clay or slag, combining environmentally friendly materials in a low-energy process. 3.

Raw Material Substitution - Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
