Investigation of fracture parameters of self-compacting concrete produced with marble powder by peak-load method

Abstract

Fracture parameters are among the most important characteristics of hardened concrete. In this study, SCC was investigated via the two-parameter fracture model (peak-load method) which needs two fracture parameters namely: the critical stress intensity factor KIC s and the critical crack mouth opening displacement CTODc to characterize failure of concrete structures. In SCC mix, different marble powders were used as powder materials. Marble powder is a new material for concrete. Marble powder is a limestone origin waste material. Samples 150x150x150 mm and 150x150x450 mm in size were produced. It is known that there is a close relation between concrete compressive strength and fracture parameters. Critical stress intensity factor KIC s and critical crack tip opening displacement CTODc, fracture parameters were determined. Consequently, it was observed that concrete compressive strength and powder admixture are effective on fracture parameters of SCC. © 2013 Sustainable Construction Materials and Technologies.
