AbstractAbout AuthorsReferences
At present, the production of structural high-strength concretes is not complete without the use of mineral and chemical additives, since with their help high technological, operational, and economic indicators are achieved. When exposed to a load, such concretes must have strictly defined deformation properties. Therefore, one of the main parameters for such concretes is the modulus of elasticity and Poisson’s ratio. If the effect of mineral additives on the deformation properties of concrete is well studied, then the effect of chemical additives is practically not studied. This is especially true in view of the emergence of a wide variety of chemical additives-superplasticizers. In this regard, a study was made of the influence of superplasticizers of different generations on the structure and properties of the cement stone of concrete, its modulus of elasticity and Poisson’s ratio. In the first part of the study, the influence of superplasticizer additives on the composition and structure of cement hydration products was studied. In the second part, the influence of superplasticizer additives of different generations on Young’s modulus, Poisson’s ratio and other characteristics of high-strength concrete is established. As a result, it was shown that superplasticizers significantly affect the composition and structure of hydrates in cement stone, which significantly changes the deformation properties of concrete.
