Information × Registration Number 0124U001714, R & D request Title Modified fine-grained concretes on composite Portland cement Head Shyskin Oleksandr O., д.т.н. Registration Date 14-02-2024 Organization Kryvyi Rih National University popup.description1 The object of research planned for implementation is fine-grained concrete on composite Portland cement. Due to the significant content of waste from the metallurgical industry and natural materials in its composition, composite Portland cement belongs to environmentally acceptable products. However, the insufficient rate of formation of its structure and, as a result, the value of the main quality indicator, which is strength, limits the field of use of composite 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 composite Portland cement. The basis of actions to achieve the set goal is based on known studies of the impact of Portland cement modification with water activated by the use of the hydrophilic 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 composite 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 composite Portland cement by using water activated by the mechanism of hydrophilic hydration. popup.nrat_date 2024-12-09 Close
