Mechanical and Thermal Properties of Lightweight Concrete Made from Expanded Glass

Production and characterization of lightweight vermiculite/geopolymer-based panels

“…The use of lightweight (expanded) aggregates, namely vermiculite, perlite, pumice, etc. with different kinds of inorganic binders, such as cement, gypsum or geopolymers, allows the production of composites masonry blocks, walls and panels with reduced apparent density, good mechanical performances and improved thermal properties (insulation, refractoriness and fire resistance) [6][7][8][9][10][11][12][13][14].…”

“…In the last few years, numerous studies were made on cellular or lightweight concrete materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14], with thermal conductivity in the range 0.1-1 W/mK. In accordance with the sustainable development policies in buildings and constructions [15][16][17], the use of lightweight materials allows to reduce both the weight of the structure (i.e., the dead load [12]) diminishing the use of raw materials and wastes, and heat transfer preserving operational energy [18] and fostering better indoor thermo-hygrometric comfort conditions.…”

Parametric Numerical Assessment of the Energy Efficiency and the Environmental Impact of an Innovative Masonry Construction Component

“…After conducting an experimental and numerical investigation on the properties of fired clay bricks containing organic matter, Aouba et al (2015) noted that the addition of wheat straw residue can improve thermal transmittance by more than 20%. Bumanis et al (2013) tested concrete mixtures incorporating expanded glass aggregates that can potentially be used for the fabrication of lightweight masonry blocks. Although the compositions examined exhibited limited compressive strength (4.0-5.8 MPa), thermal conductivity values as low as 0.140 W/mK could be achieved.…”

Chloride Penetration in Lightweight Aggregate Mortars Incorporating Supplementary Cementing Materials

“…Concrete is the world's most used construction material. Current estimates put global concrete production at around 10 km 3 per year, and this number continues to increase due to massive urban and national infrastructure development all over the world [1]. Because of the sheer volume of concrete used and the associated resources and energy required to produce it, the wise use of this material can significantly contribute in achieving rational development.…”

“…eir use has lower local environmental impact since lightweight aggregates are often made from industrial by-products (i.e., fly ash aggregates). On the other hand, natural resources, such as pumice, perlite, or scoria, could also be used instead of the conventional limestone aggregates, increasing the economical impact that the exploitation of additional natural resources offers [3][4][5][6][7]. Finally, lightweight aggregates provide lower coefficient of thermal expansion and superior heat and sound insulation characteristics in the lightweight aggregate concrete (LWAC), due to their inner air voids [8][9][10][11].…”
