BEHAVIOR OF CLAYDITE AT THE STAGE OF MICROCRACK FORMATION

Abstract

In view of the increase of structural lightweight concrete importance the studies of the lightweight concretes under static loading (single and low-cycle) are conducted within the frameworkof the state program of scientific research "Building Materials and Technologies" on the basis of the Belarusian-Russian University. The purpose of the research is to develop the national application of the Republic of Belarus to Eurocode 2. In the paper the results of the experimental research of claydite concrete with the use of expanded-clay gravel as fine aggregate are presented and the dependencies for determining the relative loads corresponding to the upper and lower limits of microcracks formation are proposed.
