Comparison of material properties of lightweight concrete with recycled polyethylene and expanded clay aggregates
(Procedia Engineering, 2017)The article discusses the possibility of using high and low density polyethylene waste as aggregate in lightweight concrete with high strength cement mortar. Research is dedicated to experimental investigation and comparison ... -
Development classification scheme for evaluation dwellings sound insulation performance in Lithuania
(Procedia Engineering, 2013)Sound classification scheme opens new enhanced possibilities to ensure noise protection in buildings and included in Lithuanian legislation in force since 2004 as a Building Regulation STR 2:01:07. The classification scheme ... -
Early hydration of calcium aluminate cement blended with spent FCC catalyst at two temperatures
(Procedia Engineering, 2013)The early hydration (up to 24h) of calcium aluminate cement (Al2O3 min. 40%) blended with spent FCC catalyst at two temperatures i.e. 10 °C and 25 °C was investigated. The calorimetric measurements were used to study ... -
The effect of temperature on the formation of the hydrated calcium aluminate cement structure
(Procedia Engineering, 2013)The effect of temperature on the formation of the structure and phase composition of the Gorkal 70 grade calcium aluminate cement (CAC) during its hydration (W/C=1) at the temperature of +5 ºC, +20 ºC and +40 ºC is ... -
The investigation of alkali – silica reactivity (ASR) of Lithuanian aggregates
(Procedia Engineering, 2017)The potential alkali-silica reactivity (ASR) of Lithuanian aggregates from five quarries was investigated using national chemical method, accelerated mortar bar test method RILEM AAR-2 (specimens 40×40×160 mm) and storage ... -
Investigation of reverberation time in different purpose rooms
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Good acoustical qualities are essential in spaces in which speech communication is important. Excessive background noise or reverberation in such spaces interferes with speech communication and thus presents negative ... -
Investigations on physical-mechanical properties of effective thermal insulation materials from fibrous hemp
(Procedia Engineering, 2017)Depletion of fossil fuels resources and large amounts of pollutants emitted to the atmosphere enforce searching for alternative renewable resources. One of these resources is fibred hemps. The main components obtainable ... -
Physical properties and structure of composite made by using hemp hurds and different binding materials
(Procedia Engineering, 2013)Maximum power consumption comes to building heating, which depends on the efficiency of building envelopes. Energy consumption of building sector covers 50% of the total energy consumption. Reducing building energy cost ... -
A porosity prediction methodology of building ceramics with burning-out additives
(Procedia Engineering, 2013)A methodology for prediction of the porosity of building ceramics caused by burning-out additives are proposed in the present article. The methodology is suitable when particles of burning-out additives is much larger ... -
The sound classification scheme of buildings as a Lithuanian regulation for protection against noise: 10 years usage experience
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Different needs for quietness in working and living environment can be expressed by introducing classification scheme defined as a set of minimum two classes with different limit values for acoustical performance. One of ... -
Stress relaxation in expanded polystyrene (EPS) under uniaxial loading conditions
(Procedia Engineering, 2013)The stress (σ10%, σcr) and strain (εcr, E) characteristics of expanded polystyrene (EPS) boards made from EPS 100, EPS 150 and EPS 200 under short-term compression are presented. The measured stress relaxation in these ...
