The use of fractal geometry in determination of fracture toughness of metakaolinite modified concrete

The aim of the paper is to present the results of experiments on concretes after 180 days of hardening with metakaolinite addition. Measurements of compressive strength fc, critical stress intensity factor KIcS and fractal dimension Dm were performed. The plan included nine measurement points. Wate...
