Sensitivity and uncertainty estimation of cement paste properties to microstructural characteristics using FOSM method

The spatial distribution of microstructures in cement paste affects its mechanical and thermal properties. To evaluate the material properties of cement pastes statistically, sensitivity analysis using the first-order second-moment (FOSM) method is performed. Two random variables, namely porosity and pore continuity, are selected as input variables, and the stiffness and thermal conductivity of cement paste are selected as output variables. The...
