| الوصف: | The research developments in materials science in the construction field concerning the formulation and production process of fine-grain concrete are aimed at the formation of structure and properties that provide the appropriate performance characteristics. The literature review and experimental data on the concrete treatment made show that the required quality of concrete can be achieved by changing the concrete mixture composition, activation of aggregate and mixing water, introduction of multi-purpose modifying additives, different approaches, etc. The paper presents the development of the effective multi-purpose additive consisting of such industrial wastes as marble-microcalcite, nano silicon dioxide, microsilica, and peat hermally modified at 600 °C. The influence of this additive on hydrated cement and concrete properties is studied herein. It is shown that the introduction of the multi-purpose additive in an amount of 5 % with a decrease in the cement consumption, improves the compressive strength of hydrated cement stone up to 69 %. The chemical composition of new formations of modified hydrated cement is determined by the physicochemical analysis. |
