| Title of the article | The influence of plasticizing additives on the composite Portland cements corrosion resistance |
| Abstract. | Problem statement. In connection with the increase in the volume of construction of unique, high-rise buildings with deep pile foundations and underground parking and construction, reconstruction and repair of important hydraulic structures, it is necessary for scientists and researchers to study the corrosion properties of composite Portland cements, which have become widespread recently, especially those based on thermally activated clays and carbonates. Super- and hyperplasticizers play a major role both in the manufacturing of high-tech hydraulic concretes and in relation to composite cements with mineral additives. The purpose of the work was to study the corrosion resistance of composite Portland cements with additives of thermally activated clays and carbonate rocks, both separately and together with plasticizers. The objectives of the study were to assess the corrosion resistance of composite cement stone at the age of 6 months and to study the effect of plasticizing additives on corrosion properties depending on the type of plasticizer. Results. The corrosion resistance of the studied samples of composite Portland cements with additives of thermally activated clays and carbonates, both with and without plasticizers, was higher than 0.8. At the same time, the use of plasticizers allows increasing the corrosion resistance of composite cement stone by an average of 5-30% depending on the type of plasticizing additive, the type of mineral additive and the aggressive environment. Conclusions. The significance of the obtained results lies in the possibility of using compositions of composite Portland cements with additives of thermally activated clays and carbonates, both in combination with plasticizers and without them, in the manufacture of concretes exposed to the corrosive effects of liquid environments during operation. |
