The article describes the positive effect of cement ground modification by polymer stabilizers. The influence of the latex polymer stabilizer Nanoterrasoil, manufactured by NanoSky (Germany), and the polymer acryl-based stabilizer (SAP) on the physico-mechanical parameters of a light sandy loam exposed by Portland cement stabilization has been investigated. The effect of acrylic polymer on the microstructure of the cement ground based on light sandy loam has been studied. It has been established that when introducing the polymer stabilizer Nanoterrasoil (NTS) (1-1.5 wt. %) into the cement-ground mixture with a simultaneous decrease in the cement consumption, the final product - cement ground acquires the increased compression strength (28 days) in water-saturated state and saturation coefficient. Significant increase of physico-mechanical parameters has been established even in case of loam stabilization by acrylic polymer (SAP), even without cement introduction. The cement ground modified with acrylic polymer is characterized by a solid fusion microstructure. This proves that the individual organic ions of the acrylic polymer, when introduced into the cement ground, are adsorbed on the surface of the solid particles of clay minerals, enveloping and bonding them during polymerization, forming a complex organo-mineral system.

The European Green Deal is the latest climate and environmental protection program launched by the EU. This is a strategy to transform the EU into a resource-efficient economy, in which in 2050 there will be zero greenhouse gas emissions and economic growth will be decoupled from the use of natural resources. After approving the National Economic Strategy for the period until 2030, Ukraine joins and focuses on the European Green Deal and aims to achieve climate neutrality in 2060 (Natsionalna ekonomichna stratehiia, 2021). Such ambitious goals can become a huge challenge for our country, in particular, in environmental projects of recycling in construction. Popularization of the principles of the circular economy and the introduction of the best European experience in the reuse of industrial waste is not only a requirement for the successful accession of Ukraine to the EU, but also a prerequisite for the effective implementation of infrastructure projects, especially the post-war reconstruction of the country.
