Objective of the course – aims of the course unit:|
The aim of the subject is to acquaint the students with basic knowledge necessary for the task to design composition of concrete with demanded final properties. During lectures information will be presented concerning the basic properties of input raw materials for concrete manufacture and the testing methods. Afterwards the students will be familiarized with marking of concrete, demands concerning the physico-mechanical properties of concrete and with testing methods. The demands will be described for the composition of watertight concrete, frost resistant concrete and of concrete for roads, subsequently to the design of their composition.
Objective of the course – learning outcomes and competences:|
The student would manage the goal of the subject by acquiring basic necessary knowledge for the proposal of concretes composition for final properties of concrete assigned in advance, by acquiring information on the basic properties of input base material for the production of concrete and their testing, by getting acquainted with concrete marking and requirements on their physical-mechanical properties and testing methods.
The knowledge of basic concrete components i.e. of cement and aggregates.
Course contents (annotation):|
Classification and types of concrete. Components of concrete: aggregates, water, cement, inert and active admixtures, accessories changing the hydration kinetics, plasticizing and areating accessories etc., structural steel. The composition of concrete, methods of calculation. Rheology of
fresh-concrete. Processing of fresh concrete, form systems and moulds. Compacting of fresh concrete mainly by vibration, other compacting methods. Hardening of concrete: hydration of cement, quick hardening of concrete, concreting in winter, treatment of concrete. The properties of concrete: porosity of the cement stone, coherence with steel, internal tension and deformation, permeability. Mechanical properties of concrete, influencing the concrete strength, deformation properties, water - tightness. The durability of concrete: frost resistance, chemical corrosion of concrete, corrosion of steel. Energetic demands for concrete production, quality control, recycling of concrete.
