“…The high aggregate content in concrete paving blocks results in a zero-slump concrete mix. The machine used in the manufacture of paving blocks should have the capacity to produce paving blocks of a high quality by providing a high level of compaction through the use of hydraulic pressure and high intensity vibration to the moulds in order to remove entrapped air and increase the density (Limbachiya et al, 2016).…”

Concrete block pavements have become an attractive engineering and economical alternative to both flexible and rigid pavements because of it’s high strength and durability. The influence of pozzolanic mineral additions – natural zeolite and expanded perlite powder on the properties of concrete interlocking blocks in different curing conditions has been studied. The use of zeolite as a substitute for cement in the production of concrete blocks increased the water demand but decreased the water absorption of the blocks. Obtained results show, that concrete blocks with 10% substitution of cement with zeolitic tuff is characterized by higher strength, lower mass loss and absence of efflorescence.

“…According to the previous articles and trial test results [24], the final replacement levels of CG were decided as 10%, 20%, 30% and 40%. GGBS was used to replace the cement with replacement levels selected as 30%, 50% and 70% according to the previous test results [14,25].…”

“…In general, the research studies suggested that the amount of rubber shall not exceed 25% of the total aggregate volume [11][12][13]. Furthermore, as a commonly found industrial waste material, ground granulated blast furnace slag (GGBS) is also investigated as a material to replace some of the cement during the concrete products' manufacturing [14].…”

Recycled aggregates have been widely studied and used in concrete products nowadays. There are still many waste materials that can be used as recycled aggregates other than crushed concrete particles. This paper aims to study the property variations of sustainable concrete paving block incorporating different contents of construction wastes. Five different types of waste materials were used in this project, including: recycled concrete coarse aggregate (RCCA), recycled concrete fine aggregate (RCFA), crushed glass (CG), crumb rubber (CB), and ground granulated blast furnace slag (GGBS). According to the test results of the properties of blocks mixed with different levels of wastes materials, it is concluded that adding both RCCA and RCFA in the block can decrease its strength and increase the water absorption. The suggested replacement levels for RCCA and RCFA are 60% and 20%, respectively. Mixing crushed glass in the concrete paving blocks as a type of coarse aggregates can improve the blocks’ strength and decrease the blocks’ water absorption. Addition of crumb rubber causes a significant deterioration of blocks’ properties except for its slip resistance.

A geração e a disposição de resíduos oriundos da fundição de metais despertam a necessidade de alternativas que promovam seu melhor reaproveitamento em processos produtivos. Assim, este estudo realizou a caracterização química, mineralógica e granulométrica de resíduos de fundição de ferro cinzento e nodular e avaliou sua aplicabilidade na construção civil. A areia verde, escória e material particulado apresentaram em sua composição química a presença majoritária de dióxido de silício (SiO 2), além de óxido de alumínio (Al 2 O 3), óxido de potássio (K 2 O) e óxido de ferro (Fe 2 O 3). A análise mineralógica revelou a presença de quartzo em todos os resíduos e de hematita, na escória. Os três resíduos apresentaram granulometrias compreendidas entre 0,002 e 0,6 mm. Identificou-se que os resíduos possuem potencialidade de uso na produção de cimento, argamassas e materiais cerâmicos, como substituintes parciais dos agregados miúdos do concreto e como material da camada de sub-base de pavimentos. Palavras-chave: produção de peças fundidas; subprodutos; composição química e mineralógica; reaproveitamento; cerâmica e concreto.
