Bio-derived rheology modifying agents for cement-based materials
(Springer, 2020)In recent few years, significant development has been made in concrete technology to accommodate the requirements of high-performance concrete. Rheology Modifying Agents (RMAs) (such as superplasticizers) and Viscosity ... -
Biomineralization in self-healing cement-based materials: investigating the temporal evolution of microbial metabolic state and material porosity
(American Society of Civil Engineers, 2017)The potential for self-healing of concrete via biomineralization processes in which microorganisms influence mineral precipitation is promising. To embed microorganisms within a cement-based material, key challenges are ... -
Fly-ash evaluation as potential EOL material replacement of cement in pastes: Morpho-structural and physico-chemical properties assessment
(MDPI, 2022-04-24)The main objective of the study was to produce alternative binder materials, obtained with low cost, low energy consumption, and low CO2 production, by regenerating end-of-life (EOL) materials from mineral deposits, to ... -
Predicting pore volume, compressive strength, pore connectivity, and formation factor in cementitious pastes containing fly ash
(Elsevier, 2021-09)This paper describes the use of thermodynamic modeling to predict the reaction products and properties of cementitious pastes containing fly ash. A pore partitioning model is used to estimate the gel and capillary pore ...
