“…Another factor may be the replacement of natural aggregates with SPS and the resulting increase in the surface area of fine particles, which can lead to weakening of interfacial transition zones (ITZ) between the aggregates and the cement paste. Similar results have been reported elsewhere [7,28]. Some previous studies [10,29] reported that the strength of LWAC depends on the strengths of the LWA used and the hardened cement paste, as well as the bonding of the aggregate/cement paste in the ITZ [30,31].…”

“…La literatura en el campo del hormigón con EPS está principalmente dedicada a la caracterización de las propiedades mecánicas de estos materiales, tratando de mejorarlas utilizando EPS de diferentes granulometrías, aditivos y distintas adiciones como cenizas volantes y humo de sílice (11)(12)(13). Otros trabajos además de caracterizar térmica y mecánica-mente el hormigón con EPS proponen métodos de modelización para predecir estas propiedades y optimizar la consecución de ambas simultáneamente (14).…”

“…The literature in the field of concrete with EPS is especially about the characterization of the mechanical properties of these materials, trying to improve those using EPS of different grain sizes, additives and other additions such as fly ash and silica fume (11)(12)(13). Other studies characterize the mechanical and thermal EPS concrete properties.…”

“…Foram obtidos cimentos com densidade variando de 1500 a 2000 kg/m³ com resistência entre 10 e 20 MPa, para adição de isopor na faixa de 20 a 40% em volume. Tang et al [14] adicionaram poliestireno expandido na faixa de 20 e 60% de volume, relatando que a densidade, a resistência mecânica e o módulo de elasticidade do compósito diminuem em função da concentração do poliestireno expandido da mistura. Além disso, as retrações em longo prazo dos compósitos são fortemente dependentes da fração volumétrica do poliestireno expandido e do tempo de cura.…”
