Damage of prestressed concrete railway sleepers and its impact on durability
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Prestressed concrete railway sleepers are the most widespread sleepers due to their stiffness and high bearing capacity. They transfer train induced loads from the rails directly to the ballast and therefore are the most ... -
Deformations of foundations of windplant installation crane sites and their reasons
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Road and foundation deformations in modern Lithuanian construction are one of the most important problems. Constantly rising conflicts between customers and builders due to poor quality of foundations show that Lithuanian ... -
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 ... -
Design errors and performance defects as causes of the risk for a collapse of the ceiling of the concert hall
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The issue presented concerns the proper assessment of a ceiling underneath a modernised concert hall in a historic building as a case study. The reason for a reconstruction was to replace a wood block floor with stone slab ... -
Development of an anchorage prototype for CFRP stress-ribbon systems using 3D printing technique
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Compared with other structure types, stress-ribbon systems are extremely simple though requiring massive anchorage blocks because of very large tensile stresses induced in the ribbons. Such structural systems are efficient ... -
Effect of aggregate particle shape and granulometry on the workability and mechanical properties of glass reinforced concrete
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Modern alkali resistant glass fibers (ARG) modified with 17% ZrO2 are getting more popular as reinforcement of cementitious matrixes. Typical matrix compositions with quartz, Portland cement, 13 mm length ARG glass fibres ... -
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 ... -
