Approach to Design of Composition of Current Concrete with Respect to Strength and Static Elasticity Modulus
Authors: Klara Krizova, Rudolf Hela
Abstract:
The paper reflects current state of popularization of static elasticity modulus of concrete. This parameter is undoubtedly very important for designing of concrete structures, and very often neglected and rarely determined before designing concrete technology itself. The paper describes assessment and comparison of four mix designs with almost constant dosage of individual components. The only difference is area of origin of small size fraction of aggregate 0/4. Development of compressive strength and static elasticity modulus at the age of 7, 28 and 180 days were observed. As the experiment showed, designing of individual components and their quality are the basic factor influencing elasticity modulus of current concrete.Keywords: Concrete, Aggregate, Strength, Elasticity Modulus, Quality
