Abstract

Izgudrojums attiecas uz būvniecību un inženierzinātni, un tehnoloģiju, proti, uz paņēmienu betona un cementa kompozītu ilglaicīgo īpašību noteikšanai dažādos sprieguma stāvokļos. Paņēmienā piedāvāts šļūdes deformācijas stiepē noteikt, izmantojot koncentrētas stiepes (CT) paraugus, kas dod iespēju samazināt eksperimentālo rezultātu izkliedi un ir īpaši piemērots smalkgraudainu betona un cementa kompozītu deformāciju nolasīšanai, izmantojot tikai vienu digitālo deformāciju.
