Optimization of aggregate composition with max. grain 22 mm for concretes
Opat, Lubomír ; Vojtek, Miroslav (referee) ; Hela, Rudolf (advisor)
This bachelor thesis deals with the issue of aggregate curve design, proportional representation of the individual separated aggregate sizes in the formula for concrete mixture. It clarifies the origin of aggregate types, from their mother rocks. It describes tests on aggregates, including the test of the shape suitability. In the practical part, there are nine formulas, two of them mixed with the maximum grain size of 16 mm, seven with the grain size of 22 mm. They are instances of fine curves or mixture of coarse curve. Aggregate dust or crushed fine aggregate was also used.
