Possibility of producing lightweight, heat insulating bricks from pumice and H3PO4- or NH4NO3-hardened molasses binder

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.…”

Use of iron ore mine tailings in infrastructure projects

“…Replacing normal aggregate by expanding perlite reduced the thermal conductivity of the mixtures as a result of the porous structure of the perlite. Benk and Coban (2012) studied the production of lightweight, heat insulating and water resistant bricks from lightweight aggregate like pumice and EP. The raw pumice was poured into the water and then floated aggregates were selected for the mixture.…”

Analysis of Sustainable Materials for Radiative Cooling Potential of Building Surfaces

“…It has 2-5% combined water. If heated to temperatures between 760 • C and 1150 • C, it expands 10 to 30 times of its original volume, depending on the raw material mixture [37][38][39].…”
