description: The given work is devoted to study self-compacting concrete technology and relationship between the properties of self-compacting concrete and superplasticizers and mineral admixtures as a partial replacement for cement.
The research set the following goals:
1. Analytical review of Russian and foreign literature to study the history of the development of SCC technology, the basic principles for producing of SCC, requirements for SCC, the influence of composition parameters on the properties of SCC.
2. Review of mineral admixtures for SCC and chemical admixtures - superplasticizers.
3. Analytical comparison of the effect of mineral admixtures and superplasticizers on the properties of SCC.
4. The choice of the most effective, from the point of view of the effect on the properties of the SCC and from an economic point of view, admixtures and their dosages for the SCC.
The study of the technology of self-compacting concrete and the effect of mineral admixtures and plasticizers on the properties of the self-compacting mixture based on results of foreign researchers during practical experiments and testing of self-compacting mixtures using various mineral admixtures and superplasticizers. All tests conducted by the authors of the works based on European standards EN 12350-8:2010, EN 12350-9:2010, EN 12350-10:2010, EN 12350-11:2010, EN 12350-12:2010, which are dedicated to self-compacting concrete mixtures. Analysis of the results cited by scientists indicated that the addition of mineral admixtures to the self-compacting mixture as a partial replacement for cement affects the workability of the mixture and the strength properties of hardened concrete. During the analysis, the most optimal, from the point of view of the impact on the properties and cost of concrete, dosages of mineral admixtures were established. It was established that the effect of superplasticizers on the properties of a self-compacting concrete mixture depends on the dosage of the chemical admixtures in the mixture and on the chemical basis of the superplasticizer. The mineral admixtures considered in this work and their dosages can be used in designing of self-compacting concrete.
