The efficiency of plasticizing surfactants in alkali-activated cement mortars and concretes

open access: yesMATEC Web of Conferences, 2018
Functionality of mortar and concrete mixes is regulated by surfactants, which act as plasticizers. The molecular structure of these admixtures can be changed during hydration of alkali-activated cements (AAC).

A consistent estimator for confounding strength

open access: yesMathematical Statistics and Learning
Regression on observational data can fail to capture a causal relationship in the presence of unobserved confounding. Confounding strength measures this mismatch, but estimating it requires itself additional assumptions. A common assumption is the independence of causal mechanisms, which relies on concentration phenomena in high dimensions.
