Predicting air‐entraining in cement paste from the molecular attributes of nonionic surfactants with a multilayer method

Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Abstract The novelty of this study is to present a multilayer framework for predicting the air‐entrained porosity of cement paste based on the molecular characteristics of nonionic surfactants. Air‐entraining agents enhance concrete durability against freeze–thaw damage; however, their development is labor‐intensive and cost‐prohibitive.

The Impact of DNA as a Chemical Admixture for Cementitious Materials

Advanced Materials Technologies, Volume 10, Issue 15, August 7, 2025.
DNA molecules are added to cement pastes and their effects on rheology and hydration time are studied. DNA's chemical structure is composed of polysaccharide and phosphate groups, which are active functional groups in different commercial chemical admixtures: Viscosity modifiers and superplasticizers.
