DETERMINATION OF ELASTIC PROPERTIES OF CEMENT-SAND COMPOSITION USING STRUCTURAL SIMULATION MODELING

Abstract

The estimation of quantitative influence of fine-grained concrete structural elements on its strength characteristics is a very actual task requiring application of computer technologies. In this article, the authors propose a structural and simulation model of cement-sand composition, which includes pores, cement stone, sand and the contact zone between them. As a result of the numerical calculation of this model, the integrated elastic characteristics of the material (modulus of elasticity and Poisson's ratio) are obtained, which can be assignedas initial data for the model of a higher scale level in order to optimize the composition of concrete.
