Lightweight Building Materials

FAST-BJ010Acad. year: 2018/2019

Information about all produced light building materials, their production, properties and utilization in building work. In the theory of Lightweight Building Materials, the classification of light building materials is involved and the general basic properties etc. Into the second part - the technology of lightweight aggregates, the knowledge of natural cellular aggregates and of concrete produced from them is involved, further untreated industrial wastes (for instance cinder, fly ash from power plants etc.), further treated industrial wastes used as porous aggregates (slag, fly ash aggloporite), synthetically produced porous aggregates and the classification of them (for instance ceramsit, expandit, perlit, vermikulit etc.). Between these materials belong even light organic aggregates( sawdust, wood shavings, light aggregates from plastics) and mineral fibres. The third part is the technology of -cellular concrete, beginning with the classification of cellular concrete, the used raw materials, processing, shaping, autoclaving etc. till to the individual products and their utilization.

Learning outcomes of the course unit

After the successful completion of the course students will be acknowledged with the latest trends and they will gain the expert knowledge in the field of lightweight building materials. Particularly it concerns the classification of the lightweight building materials, various technologies of its production and processing. Furthermore it includes the knowledge of the physico-mechanical and utility properties, those of which results their possible use in building industry. Based on this knowledge graduates are able to:
• define natural and artificial porous aggregates including the determination of the properties of concrete made of these aggregates,
• describe of technology of lightweight building materials production,
• describe in detail the various technologies of cellular concrete production and their manufacturing differences including the possibility of secondary raw materials utilization,
• define the ways of optimal lightweight building materials utilization in construction according to their property characteristics,
• describe the possibilities of industrial waste utilization as a lightweight building materials or as a raw material for lightweight building materials production.

Prerequisites

Theoretical and Technological Fundamentals of Inorganic Building Binders, namely the chemistry and technology of plaster, lime and cement manufacture.Basic knowledge necessary for the task to design composition of concrete with demanded final properties, the basic properties of input raw materials for concrete manufacture and the testing methods.General overview of ceramic raw materials properties, their processing, shaping methods in ceramics, drying, burning, properties of burnt body

Co-requisites

The student who will sign up for the course should be able to understand the basic concepts of mining and preparation of raw materials and binders. During the course the students will necessarily apply their knowledge in the field of physical chemistry, building materials physics, laboratory methods knowledge, environmental technologies of secondary raw materials utilization and optimal building materials utilization.

Recommended optional programme components

Within the course of lightweight building materials the students will be allowed to attend seminars and conferences co-organized by Brno University of Technology, Faculty of Civil Engineering. Furthermore they can participate in traditional excursion to the building materials production factories organized by the Institute of Building Materials and Components and Faculty of Civil Engineering.

Recommended or required reading

Not applicable.

Planned learning activities and teaching methods

The content of the lectures is prepared in the digital form of presentations with the largest share of graphic details that will allow to closer understanding the objective issue. The content of exercise lectures is based on the digital presentation of task, which is then clearly undertaken by experiment and then student must compile and evaluate the results in the reports.

Assesment methods and criteria linked to learning outcomes

Students process protocols during the practical exercises. Student`s participation in practical exercises is compulsory. The credits will be awarded to the students on the basis of the submission of properly processed protocols, adequate participation in practical exercises and on the basis of a successful final test passing (with the success rate of at least 65 %). Subsequent exam of this course consists of written and oral parts. For successful completion of the course the student must succeed

Language of instruction

Czech

Work placements

The possibility of work traineeship will be offered to several student candidates. Internships with companies in the Brno vicinity are pre-arranged in the following areas relating to lightweight building materials: production of expanded polystyrene, the production of lightweight wood-concrete composites and in the research of the lightweight aggregates of industrial wastes production.
