13. Construction and demolition waste in concrete: property of pre-molded parts for paving
Abstract Construction and demolition waste (CDW) production is a growing factor on a global scale and its incorrect disposal becomes an increasingly common problem in cities. It is estimated to represent, on average, 50% of the urban solid waste mass in the world. In this sense, an alternative to the destination is their reuse. In this work, the properties o

14. Analysis of generation and characterization of construction and demolition waste on construction sites in the city of Recife, Brazil
ABSTRACT In order to planning the Construction and Demolition Waste (CDW) management approach on a construction site, it is necessary to have a prior knowledge of what is being generated (qualitative analysis), the quantity that is being generated (quantitative analysis), and what is the proper final destination assigned to this material. This article propos

15. Industrial Wastes as Alternative Mineral Addition in Portland Cement and as Aggregate in Coating Mortars
This paper presents an evaluation study of wastes from pulp and paper as well as construction and demolition industries for application in cement-based materials. The alternative raw materials were used as a source of calcium carbonate (CaCO3) and as pozzolanic material (water-reactive SiO2) in partial replacement of Portland cement. In addition to the hydra

16. Thermal resistance and conductivity of recycled construction and demolition waste (RCDW) concrete blocks
Abstract In Brazil, studies to reuse construction and demolition waste are a special issue because a large amount of this material has been delivered to the public landfills and in illegal places. Some researchers have suggested reusing this material in building elements, such as bricks or blocks. It is possible to find a lot of researches in physical/mechan

17. Prediction of Chloride Ion Penetration of Recycled Aggregate Concrete
This paper provides a literature review and analysis of the various influencing aspects related to the use of recycled aggregates, sourced from construction and demolition waste, on the chloride ion penetration of concrete. A statistical analysis on the effect of incorporating increasing amounts of recycled aggregates of different type, size, and class on th

18. A new method to determine the density and water absorption of fine recycled aggregates
The construction industry keeps on demanding huge quantities of natural resources, mainly minerals for mortars and concrete production. The depletion of many quarries and environmental concerns about reducing the dumping of construction and demolition waste in quarries have led to an increase in the procuring and use of recycled aggregates from this type of

19. CARACTERIZAÇÃO E ADEQUAÇÃO DOS RESÍDUOS DA CONSTRUÇÃO CIVIL PRODUZIDOS NO MUNICÍPIO DE SANTA MARIA-RS PARA APLICAÇÃO EM PAVIMENTAÇÃO / CHARACTERIZATION AND ADEQUATION OF THE CONSTRUCTION WASTE PRODUCED IN SANTA MARIA-RS CITY FOR USE IN PAVEMENT
A indústria da construção civil é caracterizada por ser o setor que mais sofre influência com o crescimento da economia. Políticas governamentais de incentivo à habitação instigam o setor a produzir desenfreadamente, utilizando técnicas construtivas ultrapassadas e empregando mão de obra desqualificada, na tentativa de diminuir custos e encurtar p

20. Avaliação da resistência à compressão de pavers produzidos com agregados de resíduos de construção e demolição e areia de fundição / Assessment of resistance to compression of pavers produced aggregates of construction and demolition waste foundry casting sand
Neste trabalho procurou-se desenvolver um paver utilizando em sua composição agregados reciclados (brita e areia), provenientes de Resíduos de Construção e Demolição (RCD), e também foi testado areia de fundição na sua composição. Foram elaborados diversos traços com diferentes porcentagens de substituição do agregado natural pelo agregado rec

21. Performance estimation for concretes made with recycled aggregates of construction and demolition waste of some Brazilian cities
The aim of this paper is to verify the influence of composition variability of recycled aggregates (RA) of construction and demolition wastes (CDW) on the performance of concretes. Performance was evaluated building mathematical models for compressive strength, modulus of elasticity and drying shrinkage. To obtain such models, an experimental program compris

22. Indicadores de sustentabilidade como ferramenta de apoio a gestão pública de resíduos da construção civil em municípios de pequeno porte / Sustainability indicators as assessment tool to support the RCC management in small cities
Introduction: In spite of Resolution No. 307/2002 requirements for the development of an Integrated Management Plan for Construction and Demolition Waste (C&D), in all Brazilian municipalities, few have it done. And, when developed, many are designed with a short time horizon and with purely corrective function, or are adaptations of experiences from other c

23. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr
