The influence of aggregate on the properties of high performance concrete.
Bezděk, Ondřej ; Krátký, Josef (referee) ; Šiler, Pavel (advisor)
This bachelor thesis is focused on the influence of aggregates on the mechanical properties of high-performance concrete. The flexural strenght and the compressive strenght were observed after 1, 7 and 28 days. The process of hydratation was monitored using isoperibolic calorimetry. Laser particle size analysis of aggregates was also performed. As materials were used: Portland cement CEM I 42,5 R-Sc Mokrá, finelly ground silica sand, calcinated bauxite, fine test sand ČSN EN 196-1, medium test sand ČSN EN 196-1, rough test sand ČSN EN 196-1 and polycarboxylate superplasticizer Glenium Ace 40.

Inclined belt conveyor of aggregates
Švásta, Petr ; Jonák, Martin (referee) ; Škopán, Miroslav (advisor)
The aim of this work is the proposal inclined conveyor belt for transporting the aggregate maximum grain size up to 150mm. Functionalcalculation is made according to ISO 5048 Belt conveyor supportingrollers. The report contains a brief description of the function, use anddesign of the conveyor and its affiliates. On the basis of specifieddimensions is processed transporter function calculation, a simplifieddesign and conveyor tensioning devices. The work is accompanied bydrawings stretching equipment and conveyor assemblies.
Portable conveyor for aggregate
Šarman, Michal ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to design portable belt conveyor for aggregate of given parameters. The introduction contains classification of conveying machines and devices. Further chapters are dealing with the actual design of the conveyor, functional description of individual parts, selection of components, and functional calculation according to ISO 5048 standard. The final chapter specifies maximum weight delivery and overall review of the machine. The work is suplemented by mechanical drawings.
Worm conveyor of fine aggregate
Vosika, Jan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The main aim of the thesis was to design a horizontal worm-conveyor for the transport of fine aggregate of maximum aggregate gradation of 45 mm, both in terms of construction and strength. The design section of the thesis deals with the problem of an appropriate conveyor driving gear and skidding clutch between the gear and the transport unit according to the amount of transported aggregate. In the computation section, strength check of the drive system is addressed, namely the shaft check, its coupling with the other parts, and the bearing housing. In the last section, the structural design is addressed with respect to safety of operation and ease of maintenance.
Modulus of elasticity of natural stone
Hoduláková, Michaela ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
The value of the modulus of elasticity of concrete depends on the concrete composition (particularly on the aggregate used). The contemporary construction industry literature lacks comprehensive studies of the modulus of elasticity for each type of the rock stone. Therefore, this study focuses on testing and comparing the modulus of elasticity of selected types of rock stones used for the production of crushed coarse aggregates into the concrete. The modulus of elasticity are determined by static and dynamic methods. The work also deals with the modulus of elasticity of granite in different stages of weathering.
