“…Polymer concrete (PC) is a polymer composite material in which the binder is a polymer. It is used in numerous applications because of its advantages over ordinary Portland cement concrete, which include high strength and durability, fast curing time, very good adhesion properties, resistance to chemical attack, and good sound and thermal insulation properties . PCs are used in the production of a variety of products, such as precast members, structures, acid tanks, manholes, drains, highway median barriers, and coating or repair materials, in the chemical and food industries …”

In this paper, first we investigated the effects of the amount of crushed basalt aggregates on the compressive strength, flexural strength, and splitting tensile strength of a polymer concrete (PC) obtained by epoxy resin. We found that increasing the amount of epoxy resin to the basalt aggregates to 25 wt% improved mechanical properties of the concrete. After determining the optimum weight percentage of basalt in epoxy, the mechanical properties of the optimized PC were experimentally investigated at three different temperatures: 50 C, 75 C, and 100 C. Our results indicate that as the temperature increases, the highest maximum stress rapidly decreases, but the yield displacement increases significantly. Moreover, the PC sample became barrel shaped under compression stress because of its ductility at high temperatures. Afterwards, effects of four different aggregate sizes, 3-5 mm, 1.2-3 mm, 0.6-1.2 mm, and microsized particles, on mechanical properties of the optimized PC were experimentally studied. We found that, the larger aggregate size outcomes higher compressive strength and lower flexural and splitting tensile strength. Finally, an empirical model for the relationships between compressive, splitting tensile, and flexural stress was derived that can be used to predict the strength of PCs.

“…O teor apresentado para a sílica está ligado aos materiais argilosos, como caulim e argila ball-clay, apresentando vários silicatos e minerais acessórios, e à presença de sílica livre, matérias-primas usadas para a produção da massa. O óxido de alumínio geralmente está associado à caulinita, Al 2 Si 2 O 5 (OH) 4 , e aos minerais acessórios. O teor de óxido de potássio apresentado na análise pode ser atribuído aos feldspatos, micas e cátions trocáveis.…”

“…Nos últimos anos a indústria cerâmica tem usado resíduos em substituição a algumas matérias-primas com o intuito de incentivar a prática de reciclagem e economizar as matérias-primas de melhor qualidade [4]. Ademais, outro grande problema tem obtido destaque devido ao descarte de resíduo de conchas de mariscos no meio ambiente: a pesca de mariscos, no município de Cabedelo (Paraíba, Brasil), é uma das atividades comerciais mais importantes da comunidade pesqueira deste município.…”

ResumoA pesca de mariscos é uma das atividades comerciais mais importantes da comunidade pesqueira do município de Cabedelo (Paraíba, Brasil). O processo de beneficiamento, após a extração do molusco, gera elevada quantidade de conchas, cujo descarte, em volume considerável, provoca assoreamento de áreas extensas e consequente desequilíbrio ambiental. Na busca do aproveitamento desses resíduos (conchas de mariscos) e visando a redução dos problemas ambientais causados, esse trabalho teve como objetivo o estudo da incorporação de pó de conchas de mariscos em massa de porcelanato. Composições cerâmicas foram formuladas a partir de uma massa de porcelanato industrial e pó de concha de marisco ou CaCO 3 comercial variando entre 0 e 7% em massa. Corpos de prova preparados por prensagem uniaxial tiveram suas propriedades tecnológicas avaliadas em função da temperatura de sinterização. Os resultados indicaram que o uso de até 7% em massa de pó de concha mantém as propriedades tecnológicas dentro dos padrões exigidos pela ABNT (Brasil) para a classificação como cerâmicas de revestimento do grupo BIa. Palavras-chave: conchas de marisco, cerâmica branca, reutilização, desenvolvimento sustentável.

“…However, this situation can be improved by using microfiller. This has been addressed previously [23][24][25]. Microfiller is a very fine powder, which can fill the gaps between aggregates and polymer; such as fly ash and silica fume [4].…”

Abstract. Polymer modified concrete or mortar is an alternative to the advancement of long serving civil engineering material -mortar and concrete. The excellence and promising benefits of modified composites have led to numerous progressive studies of its application. This paper presented a critical review from previous research on the polymer modified concrete and mortar. Both fresh and hardened state behaviours were reviewed as they are important for the development of excellent engineering material. Most of the applications of polymer modified concrete and mortar can be seen in diverse types of polymer such as latex, epoxy and emulsion. The utilization of each type of polymers resulted in different characteristics of composite concrete or mortar. Such applications have contributed to the improvement in terms of workability and mechanical strength, especially at higher grade of composite strength of concrete material.
