Cement based composites for thin building elements: Fracture and fatigue parameters
Seitl, Stanislav; Bílek, Vlastimil; Keršner, Zbyněk; Veselý, Jiří (Elsevier, 2010-06-06)For application in civil engineering structures and also for strengthening existing structures cement-based composites are one of the most frequently used materials. Although many studies have been conducted on the mechanical ... -
Comparison of Fracture Resistance of the Normal and High Strength Concrete Evaluated by Brazilian Disc Test
Miarka, Petr; Seitl, Stanislav; Bílek, Vlastimil (MPDI, 2018-05-19)Nowadays, high performance concrete is used more frequently because of the many advantages compared to traditional concrete. The higher mechanical properties (e.g., compressive strength, flexural strength, and Young’s ... -
Effect of curing environment on length changes of alkali-activated slag/cement kiln by-pass dust mixtures
Bílek, Vlastimil; Kalina, Lukáš; Šimonová, Hana (IOP Publishing, 2019-08-14)This paper investigates the combination of commonly used blast furnace slag (BFS) and quite non-traditional cement kiln by-pass dust (BD) for the preparation of alkali-activated binder. More specifically, the possibilities ... -
Fracture parameters of fine-grained composites based on the alkali-activated slag
Bílek, Vlastimil; Kucharczyková, Barbara; Šimonová, Hana; Kocáb, Dalibor; Keršner, Zbyněk (IOP Publishing, 2018-07-12)The paper deals with the experimental determination of fracture parameters of the composites based on the alkali-activated slag (AAS) at different ages. The main aim of the experimental investigation was to verify the ... -
Fracture properties of concrete specimens made from alkali activated binders.
Šimonová, Hana; Kucharczyková, Barbara; Topolář, Libor; Bílek, Vlastimil; Keršner, Zbyněk (IOP Publishing, 2017-09-15)The aim of this paper is to quantify crack initiation and other fracture properties – effective fracture toughness and specific fracture energy – of two types of concrete with an alkali activated binder. The beam specimens ... -
Glass fibre reinforced cement based composite: fatigue and fracture parameters
Seitl, Stanislav; Keršner, Zbyněk; Bílek, Vlastimil; Knésl, Zdeněk (2009-06-15)This paper introduces the basic fracture mechanics parameters of advanced building material - glass fibres reinforced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three-point ... -
Potential use of blast furnace slag for filtration membranes preparation: A pilot study
Bílek, Vlastimil; Bulejko, Pavel; Kejík, Pavel; Hajzler, Jan; Másilko, Jiří; Bednárek, Jan; Tkacz, Jakub; Kalina, Lukáš (IOP Publishing, 2018-07-12)This paper investigates the possibilities of the use of sodium hydroxide activated blast furnace slag for preparation of filtration barriers. The motivation for this research is searching for cheaper and more eco-friendly ...
