Experimental study of the behaviour of cement pastes in the presence of carbon nanotubes
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)One of the methods recently applied for the noticeably improvement of properties of cementitious materials is the use of the single or multi-walled carbon nanotubes (CNTs) as nano-reinforcements in cementitious materials. ... -
Degree of MWCNT suspension dispersity and its influence on rheology of cement pastes
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Modification of cement pastes by MWCNT (multi-walled carbon nanotubes) suspension enables to manage by their rheological properties due to the nanometer size of MWCNT. Dispersity degree of MWCNT suspension may be determined ... -
The effect of ashes on the properties of cement mortar and typical concrete fillers
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The production of heat and electricity from shale and biomass is leading to a significant increase in the amount of the combustion residues i.e. ashes. The utilization of ashes as the pozzolanic additive in the production ... -
The influence of the fireclay waste on the microstructure and the physico-mechanical properties of autoclaved aerated concrete
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Autoclaved aerated concrete is a building material with good thermal insulation properties, which it receives through the pore structure. The production of autoclaved aerated concrete consists of two phases. In the first ... -
