EXPERIMENTAL VERIFICATION OF IMPREGNATED TEXTILE REINFORCEMENT SPLICING BY OVERLAPPING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This paper presents an experimental verification of impregnated textile reinforcement splicing by overlapping using tensile test of small textile reinforced concrete slabs before its using in the product. The specimen ... -
MECHANICAL PROPERTIES IMPROVEMENT OF FIBER REINFORCED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Fiber reinforced concrete mechanical properties are limited due to low adhesion between polymer fibers and cement matrix. To ensure a strong interaction between the two materials, polypropylene fibers (d = 0.305mm) were ... -
USING SECONDARY RAW MATERIALS IN LIGHTWEIGHT OPEN-STRUCTURE CONCRETE WITH GOOD UTILITY PROPERTIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)The paper presents the results of research in lightweight concrete with open structure made using a lightweight porous foam-glass aggregate produced from recycled glass powder. The goal was to develop lightweight concrete. ... -
CHARACTERIZATION OF LIGHTWEIGHT LIME MORTARS CONTAINING BRICK WASTE POWDER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This work deals with the effects of an expanded perlite (EP) on the hardened properties of air lime mortars with a 50% brick waste powder content. The influence of different substitution of quartz sand by EP is also monitored ... -
CHLORIDE RESISTANCE OF NANO-PARTICLE REPAIRED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This paper describes the results of the experimentally modeled chloride ion penetration into different quality concrete structures with fully developed carbonation. Parts of concrete samples were further treated, to increase ... -
THE PHYSICAL PROPERTIES OF CEMENTITIOUS COMPOSITES FOR APPLICATIONS IN A HIGH-TEMPERATURE ENERGY STORAGE DEVICE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)The article was focused on experimental verification of the identification of thermal characteristics of high-performance cementitious composites at elevated temperatures. The purpose of the research was to verify the ... -
DURABILITY OF CONCRETE WITH BINDER BASED ON SULFOCALCIC FLY ASH
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This paper deals with the durability of concrete with binder based on sulfocalcic fly ash. At the beginning, in the theoretical part, there is a research on the frost resistance of concrete, its resistance to chemical thaw ...
