TRIAXIAL COMPRESSIVE STRENGTH OF ULTRA HIGH PERFORMANCE CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The aim of this work is to describe the strength of Ultra High Performance Concrete (UHPC) under triaxial compression. The main goal is to find a trend in the triaxial compressive strength development under various values ...
EFFECTIVE FRACTURE ENERGY OF ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE UNDER INCREASED STRAIN RATES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The main objective of this paper is to contribute to the development of ultra-high performance fibre reinforced concrete (UHPFRC) with respect to its effective fracture energy. Effective fracture energy was investigated ...
AN EXPERIMENTAL INVESTIGATION INTO MOISTURE-INDUCED EXPANSION OF PLASTERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This paper presents an experimental study on moisture-induced expansion of selected plasters. Contactless measurement is introduced and a coefficient of moisture expansion for different building plasters is established. ...
ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE UNDER HIGH-VELOCITY PROJECTILE IMPACT - PART 2. APPLICABILITY OF PREDICTION MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Semi-infinite targets of Ultra-High-Performance Fibre-Reinforced Concrete with various fibre volume fractions were subjected to the high-velocity projectile impact using in-service bullets. In this study, a variety of ...
ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE UNDER HIGH-VELOCITY PROJECTILE IMPACT. PART I. EXPERIMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
A series of cratering experiments were performed where the response of the Ultra-High-Performance Fibre-Reinforced Concretes with various fibre volume fractions to the high- velocity projectile impact loading was investigated. ...
USING TEXTILE ARAMID FABRICS TO INCREASE THE BALLISTIC RESISTANCE OF ULTRA-HIGH-PERFORMANCE STEEL-FIBRE REINFORCED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Thin plates made of Ultra-High-Performance Steel-Fibre-Reinforced Concrete (UHPSFRC) with textile Aramid fabrics were subjected to a projectile impact and its post-test damage was discussed. The damage degrees were the ...
Concrete lintels reinforced with steel fibres oriented by a magnetic field
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This paper explores the possibility of applying the technique of magnetic orientation of steel fibres for manufacturing a concrete structural element of realistic dimensions, compared to small laboratory specimens. This ...
EFFECT OF FIBRE ASPECT RATIO AND FIBRE VOLUME FRACTION ON THE EFFECTIVE FRACTURE ENERGY OF ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
This paper investigates the effective fracture energy of UHPFRC with various fibre volume fractions and various fibre aspect ratios. We have concluded that the effective fracture energy is dependent on both the fibre volume ...
Compression behaviour and failure mechanisms of a safety culvert made of hollow high-performance concrete blocks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
The safety culvert composed of hollow high-performance concrete blocks is designed to reduce the risk of injury in the event of a collision. This work presents a new design with an opening for water flow, tests it, identifies ...
