ESTIMATION OF POISSON’S RATIO AND E-MODULUS OF CLAYDITE CONCRETE

Abstract

In view of the increasing importance of structural lightweight concrete, experimental studies of claydite under static loading are conducted at the Belarusian-Russian University. The investigation was carried out within the framework of the state program of scientific research in the field of «Physical Materials Science, New Materials and Technologies» approved by the Council of Ministers of the Republic of Belarus. The purpose of the research is to develop the National Annex to Eurocode 2 and recommendations for reconstruction of buildings and structures. The research director is S. D. Semenyuk, Doctor of Engineering Science, Professor, the responsible person is Yu. G. Maskalkova, Ph.D. (Engineering), Associate Professor (the authors of the article).

The paper presents the results of the experimental studies of deformative characteristics of claydite concrete of different classes. The article is devoted to the question of estimation of the values of secant and tangent modulus of elasticity (E-Modulus) and the coefficient of transverse deformations (Poisson's ratio).

It will be possible, from the analysis of the obtained results, to assess the adequacy of the Eurocode 2 provisions with respect to claydite concrete manufactured with the use of Belarusian fillers.
