Layer model of elasticity modulus prediction for lightweight concretes

Building Materials

Reducing the structures’ weight is one of the basic approaches to improving the efficiency of construction. There are many developments in this area, especially with lightweight concretes. One of the problems for structural lightweight concrete is a fairly low modulus of elasticity and increased plastic deformations in extreme conditions due to the high porosity of the lightweight aggregates. Therefore, the assessment and prediction of the deformative properties of lightweight concretes is an urgent scientific task on a par with heavy concretes. Our previous work proved the performance of the layer calculation model for heavy concretes. In this research, we attempted to test the layer model when calculating the deformative properties of concretes containinglightweight aggregates.
