Diatom biosilica as a supplementary cementitious material

npj Materials Sustainability
The use of supplementary cementitious materials (SCMs) is a key method used to reduce the embodied carbon of cement-based materials. Uncertainty in traditional SCM markets has led to increased interest in alternative, natural SCM materials. In this work,

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites

Advanced Functional Materials, EarlyView.
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,

Application of Ceramic Powder as Supplementary Cementitious Material in Lime Plasters

Medžiagotyra, 2016
In this paper, the properties of plasters based on lime – brick powder binder of varying composition (ceramics content from 0 to 80 %) are studied. The plasters are prepared with a constant water amount. The pore size distribution is thus influenced in a
