The structure of cement stone with complex additives and its effect on the deformation properties of frame concrete

The modern construction of massive structures and structures requires the use of high-strength, durable and efficient cement concretes. In order to obtain the required properties in the production of such concretes, it is necessary to use complex additives that form the structure of cement stone in concrete, providing the necessary strength and deformation properties. The studies provided data on changes in the initial modulus of elasticity and Poisson's ratio of concrete without additives and depending on the complex of superplasticizer-mirco silica additives used. The study also provides data on the effect of these additives on the phase composition of cement stone, the compressive strength of concrete and its modulus of elasticity. The additives of modern superplasticizers in combination with micro silica are shown to have a different effect on the structural component of cement stone, changing the Poisson's ratio, the initial modulus of elasticity of concrete and its resistance to environmental loads.
