Elasticity modulus of cement composites predicting using layer structure model

The deformability of concrete along with the compressive strength is the determining factor in the calculation of concrete and reinforced concrete structures. In practice, with the same strength, the deformative properties of concrete, especially monolithic, can vary in a significant range, which affects the actual deflection of span structures and their reinforcement coefficient. However, the modulus of elasticity/deformation of concrete in production is not normed, and the introduction of the norm requires obtaining available bases for calculating the deformability of concrete under load from the composition of the concrete mix. The use of a layer calculation model allows you to quickly and accurately predict the elastic modulus and deformation of concrete. On the base of this model elasticity modulus depending on concrete mix components characteristics and proportions calculation method received and tested.
