Lightweight and Thermal Blocks From Zeolites as Aggregated

Analysis of the Possibility of the Polymeric Aggregates Use in the Design of Building Block

“…(1) [9]. F´c = PA -1 (1) where F´c is the compressive strength of solid materials, kg/cm 2 ; P is the load applied to the sample in study, kg; A is the cross-section, cm 2 .…”

“…However, concrete block has limitations: it is relatively heavy and possesses a poor thermal insulation. Such features can give place to the collapse of the constructions during seismic events; likewise, the intramural conditions are out of the comfort zone in extreme climates [1][2][3][4].The objective of this research is the improvement of the physical properties of concrete block by means of the addition of polyepoxide particles and/or expanded polystyrene particles, with the purpose of presenting a use option for this sort of industrial waste in the production of lightweight masonry elements, that are able to limit the transfer of heat and possess high resistance to compression [5][6][7]. The aggregates used are polymers, thermally stable, with physical properties [8] which will allow producing the material in study with the cited qualities.…”

“…However, these elements have some limitations such as weight and poor thermal insulating properties compared with others masonry materials, such as bricks. This results on possibility of constructing buildings that facilitate the collapse in seismic events and living conditions intramural outside the comfort zone in extreme climates due to the high heat transfer (Al-Hadhrami & Ahmad, 2009;Munive, Leal-Cruz, Pech-Canul, Rodríguez-García, & Rocha-Rangel, 2013;Pérez, Cabanillas, Hinojosa, & Borbón, 2011;Vergara Gonzalez, Vergara Gonzalez, Nájera Hernáez, & Otaño Jimenez, 2014). That is why today, there is a significant trend in the use of lightweight and thermal materials within the construction industry (Pérez et al, 2011;Vergara Gonzalez et al, 2014).…”

“…As an example, recent studies in the University of Sonora (Mexico), showed the development of thermal mortars with zeolite aggregate, microporous mineral located in many parts of the world, including the state of Sonora in Mexico. This type of elements showed a compression strength of 74kgcm -2 (greater than the minimum necessary in construction, 70kgcm -2 ) and a thermal conductivity of 0.37Wm -1 K -1 (77% lower compared to the traditional mortars, 1.70Wm -1 K -1 ) (Munive et al, 2013). In Argentina, the possibility of using recycled plastic as aggregates to replace coarse gravel has been analyzed.…”
