Abstract
In this study, relationships of compressive strength with tensile strength and elastic modulus was investigated for self-compacting concrete (SCC) containing different types and dosages of mineral admixtures (fly ash (FA) and silica fume (SF)). Slump-flow, T50cm, L-box and sieve segregation tests were achieved for SCC mixes. In the following day of casting, the specimens were de-moulded and located in standard 20±20C water cured for the period of 28 days. Compressive strength, splitting tensile strength and elastic modulus tests were performed using a total of 3 specimens for each concrete property. Compressive–tensile strength and compressive strength-elastic modulus formulas obtained from regression analysis using a numerous data were compared with the equations of previous studies. Consequently, it was found that compressive strength-elastic modulus formula obtained from this study has almost estimated the elastic modulus of both normal and high strength self-compacting and other concretes, whilst compressive–tensile strength formula has correctly estimated the tensile strength of high strength self-compacting and other concretes.
