Broken Beds, but better science; using multiple hypotheses to interpret geological data
Terra Nova, Volume 35, Issue 1, Page 73-82, February 2023., 2023 Abstract In this study, we propose a multiple hypotheses approach to improve interpretations of limited remotely sensed datasets, such as sparsely exposed outcrops, subsurface datasets, or planetary objects using semi‐quantitative scoring and ranking of observable features.

Formation and characterization of ceramic coating from alumino silicate mineral powders in the matrix of cement composite on the concrete wall [PDF]
Materials Chemistry and Physics, 2019, 2018 Enhancement of thermal performance of concrete wall is nowadays of great importance in reducing the operational energy demand of buildings. We developed a new kind of inorganic coating material based on \ce{SiO2}-\ce{Al2O3}-rich minerals and Portland cement (PC) powder. The finely pulverized mineral powder with the particle size distribution (PSD) of 0.

Influence of limestone filler and of the size of the aggregates on DEF [PDF]
arXiv, 2016 This experimental study aims to determine the effect of limestone filler on concrete expansion due to delayed ettringite formation (DEF). Different mortars made with different sizes and percentages of limestone filler and Portland cement CEM I 52.5N are conserved in water. The expansion of the specimens is measured.
