Basic knowledge gained in courses Technology of Concrete 1 and 2, Mortars 1 and 2, Composite materials, Durability of building materials. Knowledge of current modern trends is important for achieving special and extreme final properties, reduction of production cost and minimizing ecological load. Basic knowledge about the influence of the character of micro-structure of cement stone on physico-mechanical properties (content and distribution of micro and macro pores, interfacial transition zones between aggregate grains, influence of water-cement ratio on properties of fresh and hardened concrete is necessary. Basic knowledge of rheology of fresh concrete, ways of its measuring, behavior and effect of superplasticizers in concrete are also important.
