Owing to the significant content of metallurgical industry waste in its composition, slag Portland cement belongs to ecologically acceptable products. However, the insufficient rate of formation of its structure and, as a result, the value of the main quality indicator, which is compressive strength, limits the field of use of slag Portland cement. Therefore, in the conducted studies, the goal was to increase the speed of formation of the strength of fine-grained concrete made on slag Portland cement. The basis of actions to achieve the set goal is based on well-known studies of the effect of modification of Portland cement with water activated by the use of the hydrophobic hydration mechanism. It is planned to establish the factors affecting the speed of formation and the value of compressive strength of fine-grained concrete made on slag Portland cement. It is planned to prove that the specified factors include the type and amount of applied water nanomodifiers, as well as the type and amount of fine concrete aggregate. Thus, there are reasons to assert the possibility of targeted regulation of the processes of forming a strong structure of fine-grained concrete based on slag Portland cement by using water activated by the mechanism of hydrophobic hydration. popup.nrat_date 2024-12-09 Close
