Micromechanical Analysis of Cement Paste with Carbon Nanotubes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Carbon nanotubes (CNT) are an attractive reinforcement material for several composites, due to their inherently high strength and high modulus of elasticity. There are controversial results for cement paste with admixed ...
DIAGNOSTICS OF UNFIRED EARTH WITH METHYLENE BLUE TEST
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Unfired earth is important historic building material. Final properties of unfired earth constructions are influenced by amount and kind of clay in earth mixtures. Methylene blue test is a method that helps determining the ...
MICROSCOPIC FEATURES OF CEMENT PASTE MODIFIED BY FINE PERLITE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
The use of waste material and replacement of binder element in cementitious composites is in focus of material development. Perlite in the construction industry is usually used in form of lightweight aggregate enhancing ...
MODULUS OF ELASCITY OF UNFIRED RAMMED EARTH
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article is focused on measurement and evaluation of elastic modulus of unfired rammed earth and determination of stress-strain curve in compressive test. Sets of different containt of clay, sand and water were made and ...
DETERMINATION OF DRYING TIME OF THE RAMMED EARTH WALLS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The unburned earth is a building material with long history of use. Buildings made of unburned clay are all over the world. But at present, unburned earth is minority building material and its properties are not sufficiently ...
EVALUATION OF IMPACT OF ELEVATED TEMPERATURES ON YOUNG’S MODULUS OF GLT BEAMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The influence of elevated temperatures on mechanical behavior of glued laminated timber beams is examined on the basis of tensile tests. Dog bone samples prepared from beams exposed to fire of variable duration were ...
FRACTURE ENERGY OF ILLITIC RAMMED EARTH WITH HIGH WATER-CLAY RATIO
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The article is focused on design of mixture of rammed earth, producing, testing and determination of fracture energy of unfired rammed earth and its stress-strain curve in tensile bending test. Three different mixtures of ...
INFLUENCE OF EARTH COMPOSITION ON ADSORPTION CAPACITY OF METHYLENE BLUE DYE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Final properties of unfired earth are influenced by composition of earth mixtures. Methylene blue test could be useful method for analysis of earth composition. This would facilitate of designing unfired earth building ...
Determination of water absorption coefficient of unfired earth materials different in used clay and ratio of components
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The paper is focused on unfired rammed earth and its water absorption properties. Increasing the utilization of raw natural materials can be one of the approaches towards sustainable development. Different prescriptions ...
Methylene blue test and adsorption capacity of clays
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This article presents results of experimental measurements focused on an ability of clay to adsorb Methylene Blue dye. This adsorption capacity is determined by a methylene blue test. Adsorption capacity could be a specific ...
