| Summary: | Compressive strength is a property of significant importance for civil engineering; consequently, there have been strong need for developing method, which will estimate rise of concrete compressive strength in construction. According to Serbian legislation, assessment of compressive strength in construction relies on laboratory results obtained under constant conditions. This paper presents and compares results obtained in laboratory, results obtained by maturity method, which is based on correlation between concrete compressive strength, concrete age and ambient temperature, and the results obtained by ConReg 706 instrument, which also takes in consideration external environment and concrete temperature. Two approaches of maturity method, Nurse & Saul and Arrhenius have been applied. For this research, concrete class C30/37 was used, prepared as two different mix designs, MB35 and MB 40. Casting was performed in summer time in Ostruznica bridge near Belgrade. Elements that were casted are deck slab, pile cup and bearing beam. |
