(Procedia Engineering, 2017)Designed composition of ceramic mass for synthesis of the high-alumina ceramic substrates for production multilayer microfiltration membranes. Electrocorundum (fraction 100–250 microns) was used as filler for producing ... -
Dynamic behavior of pre-stressed slab bridges
(Procedia Engineering, 2017)In last 10 years pre-stressed in-situ slab bridges has become one of the used bridge deck type for new bridges in Latvia. This structure is used for overpasses on road junctions where height of the bridge deck and space ... -
Mechanical properties of a dike formed from a soil-ash composite
(Procedia Engineering, 2017)The paper presents the research results on application of composite soils for dike construction. The composite soil is produced by mixing bottom ash (by-product of energetics) with dredged material (sand) taken from the ... -
An experimental buckling study of column-supported cylinder
(Procedia Engineering, 2017)An accuracy of numerical prediction of buckling load of axially or locally loaded thin-walled circular shells was always been a challenge for engineers. With the introduction of new materials and manufacturing methods, ... -
Experimental study of multilayer beams of lightweight concrete and normal concrete
(Procedia Engineering, 2017)There are fibres work at compression and fibres work at tension in elements under bending actions. Even more, could be fibres which not work at all. This specific way of working leads since long time ago to the use of ... -
Reseach on the impact of fireproof impregnation by preservatives containing nanoparticles on the strength of construction timber in increased temperatures
(Procedia Engineering, 2017)In the conditions of high temperatures impact, a timber construction is subjected to simultaneous excitations in the form of forces and thermal actions. The impacts of these two factors have an effect on the distribution ... -
Defining project approach using decision tree and quasi-hierarchical multiple criteria method
(Procedia Engineering, 2017)The success of any project strongly depends on the decisions made at the initial stage of it’s life cycle. They define the general formula for project realization, specifying how the main goal of the project is going to ... -
Fire response of hybrid fiber reinforced concrete to high temperature
(Procedia Engineering, 2017)The building industry offers a wide range of materials whose structural behavior is more or less affected by temperature. While the knowledge and experience with concrete behavior under ambient temperature are well-known, ... -
Microstructural analysis of self-compacting concrete modified with the addition of nanoparticles
(Procedia Engineering, 2017)Microstructural analysis of self-compacting concrete modified with the addition of nanoparticles was carried out. Investigations included SCC concretes modified with different amounts of SiO2, TiO2 and Al2O3 nanoparticle ... -
Adiabatic temperature rise of concrete with limestone fines added as a filler
(Procedia Engineering, 2017)Limestone fines (LF) is used as an inert filler in concrete to reduce the cement consumption, reduce the heat generation during hardening and promote the sustainability of concrete construction. Basically, LF is added to ... -
Durability properties of high performance foamed concrete
(Procedia Engineering, 2017)Foamed concrete (FC) is promising material in modern building industry because of simple technology and wide range of properties may be achieved. Basic problems of FC are shrinkage and decreased strength, comparing to ... -
Influence of the production process on the selected properties of asphalt concrete
(Procedia Engineering, 2017)The paper investigates the influence of the concentration of synthetic wax modification of bitumen on the properties of asphalt concrete produced and compacted at 95°C and at 115°C. In both types of mixes the bitumen was ... -
Comparison of elastic and viscoelastic analysis of asphalt pavement at high temperature
(Procedia Engineering, 2017)There are many various rheological models which are used for modeling of asphalt layers in flexible pavement structures. It can be expected that the use of various models may affect different results of mechanical pavement ... -
Stress-strain states differences in specimens during triaxial compression and direct shear tests
(Procedia Engineering, 2017)This article compares the soil strength parameters obtained from data of triaxial compression and direct shear tests, both with dense samples of fine sand. Direct shear device and triaxial device have significant differences ... -
