Experimental Analysis of the Influence of Concrete Curing on the Development of its Elastic Modulus over Time

Popis výsledku v původním jazyce

The modulus of elasticity is one of the most important properties of concrete, especially during structural analyses of buildings. It is, among others, an important parameter in the calculation of concrete element deflection or during the design of pre- or post-tensioned structures. The modulus of elasticity is not a specific number. It is a property with a high variability of the final values, which depend on concrete composition (together with other factors). Some of the significant factors, which influence the final value of the elastic modulus of concrete, are also the means and quality of its curing, especially at the early stage of its setting and hardening. Apart from maintaining the temperature within the correct limits, it is important to focus on the moisture content of the concrete while it is being cured. The purpose of the experiment described herein was to determine the development of the dynamic as well as static modulus of elasticity for structural concrete while using different curing methods. The experiment used 4 series of beam specimens of the nominal dimensions of 100 x 100 x 400 mm made from air-entrained and non-air-entrained concretes of the C 30/37 strength class. A half of the specimens in each series aged in laboratory conditions and the other half was stored under water. Based on the evaluation of the experimental measurements, it can be said that the manner of storage has a significant influence on the development and final values of the static and dynamic modulus of elasticity.
