Mix details and material behaviour of polystyrene aggregate concrete

Abstract: Polystyrene aggregate concrete is one of many lightweight, low strength materials with good energy-absorbing characteristics. However, due to poor workability and a susceptibility to segregation, quality control is difficult during manufacture. This Paper describes the procedures adopted for the mix design and casting of concretes containing 40, 50 and 60 vol.-% (corresponding to specific densities of 0·8, 1·0 and 1·2 respectively) of beaded polystyrene aggregate. Strength and density were controlled by varyin… Show more

“…Lightweight concretes manufactured with EPS have been used in a range of applications including rendering panels, flooring, concrete blocks, road pavements and in railway and marine structures (26)(27)(28)(29). The literature on concrete containing EPS has focused on characterising the mechanical properties of these materials and has investigated the effects of using EPS with different grain sizes, organic additives and other additions such as fly ash and silica fume (10, 30,31).…”

“…Devido a sua baixa densidade, pode ser utilizado na fabricação de concretos de baixa densidade para aplicação na construção civil, tais como revestimento de painel, muro cortina, piso e blocos de concreto [3,4]. Esse material pode ser também utilizado em aplicações mais específicas como, por exemplo, base de pavimentos, leito de vias férreas, material de construção para estruturas flutuantes ou barreiras no mar e material que absorve energia na proteção de instalações militares subterrâneas [5][6][7][8][9]. Através da incorporação de esferas de poliestireno expandido em diferentes frações volumétricas no concreto, uma argamassa ou pasta cimentícia pode ser preparada resultando em ampla faixa de densidade do material.…”

“…Em alguns trabalhos, para compensar a característica hidrófoba do poliestireno, aditivos tais como resinas epóxi emulsificadas em água e dispersões de polivinilpropionato foram adicionadas [10]; ou esferas de isopor tratadas quimicamente para evitar a segregação nas misturas com o concreto [11]. Outros pesquisadores reportaram que as esferas de isopor tendem a flutuar, o que pode resultar em uma mistura não homogênea devido à segregação, fazendo o uso de aditivos necessários [6,7]. Além disso, as maiorias dos estudos foram feitos com concretos de densidades, < 1300 kg/m³, com resistência < 12 MPa.…”
