In the modern world of information technology personal computers considerably dominate our everyday life. All real, field experiments and tryouts replace computer-aided simulations as they often save a lot of time. It is much easier to make the multiple calculations related inter alia to reinforced concrete structures using strain diagrams for the concrete and rebars. This is the method ensuring the results similar to the field tests and the only challenge is that many equation parameters have to be reduced. Therefore, the objective of the work is to propose a simplified mathematical model for describing the strain diagram of a bended slag-concrete element based on air-cooled slag (ACS) and the aggregate made of sieves (0…5 mm fraction) from crashed ACS originating from NLMK’s Blast Furnace Operations, while implementation of the model helps to avoid complicated equilibrium experiments. As a result of the research and mathematical simulation of the bended element diagram a model capable of reflecting the sample behavior at any loading stage using maximum load and initial modulus of elasticity was proposed.
