The effect of a multifunctional additive and a low-activity mineral filler on the formation of porosity and microstructure of a cement composite

The article examines the effect of a multifunctional additive and a low-activity mineral filler on the formation of porosity and structure of a cement composite. The multifunctional additive includes several active components that contribute to improving the properties of the cement matrix, whereas a low-activity mineral filler is used to regulate microstructure and porosity. In the course of the work, experimental studies were carried out, including the analysis of pore morphology and particle distribution using X-ray phase and differential thermal methods. Changes in the structure of the cement composite, its strength and durability were evaluated depending on the content and ratio of additives. The results showed that the combination of a multifunctional additive and a low-activity filler leads to a significant improvement in the mechanical properties and controlled porosity of the cement composite, which opens up new prospects for the development of more efficient building materials.
