Modern Problems of Building Materials Design

Abstract
The subject of this paper is the modern models of building materials. The problem is a lack of adequate models of predicted properties of materials. As a result, the calculated strength or durability do not match with the real values. There are many models that describe the interaction between the structural elements. But each model characterizes only one property: elasticity, plasticity, viscous flow, etc. To make these models more realistic it needs to use more complicated notions about material. It has been shown that describing the connection between particles as a serial-parallel connection of springs and pistons in oil that is more realistic. Keywords - Building Materials, Elasticity, Plasticity, Viscous Flow, Durability.
