Abstract

Introduction. Ionizing radiation induces defects in the crystalline lattice of calcium hydroxide, leading to radiation-induced shrinkage. Due to shape anisotropy and aggregate deformation, these effects propagate non-uniform
stresses throughout the concrete matrix, compromising its structural integrity.
Problem Statement. In the context of addressing scientific and technical challenges, the potential to enhance
the physical and mechanical properties of CaO—Al₂O₃—SO₃ binder systems has been investigated. Given the limited availability of raw materials for alumina cement production and the high cost of imported specialty cements (25–35 thousand UAH/t), both theoretical and experimental studies on the development of advanced composite binders are of current importance.
Purpose. This study aims to develop theoretical foundations for improving the performance of mortars based on nanomodified composite binders within the CaO—Al₂O₃—SO₃ system, focusing on stabilization of the ettringite phase and optimization of nanoadditive integration technologies.
Materials and Methods. The experimental phase employed modern analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and low-temperature dilatometry, to assess the structural and phase transformations in cementitious systems.
Results. The theoretical framework for designing construction-grade mortars with ion-protective properties has been further developed. These mortars are based on composite mineral systems of the CaO—Al₂O₃—SO₃—H₂O
type, which incorporate up to 42% chemically bound water due to ettringite content. Carbon nanotubes have been
successfully used to modify sulfate and sulfoaluminate phases, resulting in improved microstructural stability.
Conclusions. For the first time, a theoretical model has been established, and experimentally validated, for
stabilizing the ettringite phase in specialty cements through the introduction of functionalized carbon nanotubes
(5—25 nm in diameter). The stabilization mechanism involves nanoscale alloying and reinforcement of the ettringite crystal structure, thereby enhancing its durability under operational conditions.
