Innovative superplasticizers for thermally activated (calcined) clays
The use of thermally activated (calcined) clays as supplementary cementitious materials (SCMs) in cement represents a promising optimization step for ordinary Portland cement in terms of environmental impact and energy efficiency.
Calcined clays are produced by large-scale calcination of naturally occurring, abundant clay minerals. They contain various phyllosilicates such as kaolinite, illite, and mica, as well as a wide range of inert minerals including silica, feldspar, sulfates, and carbonates. These clinker-reducing materials can decrease the workability of cementitious mixtures....
