“…A case study in Malaysia reported that a total of 175,000 tons and more than 100,000 tons of CDW were generated annually in Kuching and Samarahan, respectively [6]. The dumping of CDW is on or nearby a municipal solid waste landfill [7] has become one of the most common waste disposal practices due to the lack of proper management by the responsible agencies. Low pH (< pH 6) of leachate released from young municipal solid waste landfill [8] in Malaysia has possibly changed the properties of CDW due to the leaching behavior of chemical elements from such waste.…”

Recycling of Construction and Demolition Waste (CDW) aims to minimize the generation of waste and reduce the dependency on natural resources. The aims of the research are to characterize inorganic element and to determine the leaching behavior of CDW (concrete and gypsum) by means of the leaching test. The analyzed results were compared with the European Union (EU) Landfill Directive to assess their acceptance criteria. Both wastes were found to have elements of Ca, Mg, Fe, Zn, Mn, Pb, Cu, Cd, As, Cr, Se, Ni, CI and SO4 2-. The highest concentration and variety of inorganic element found in waste gypsum (WG) were SO4 2->Ca>CI>Mg>Zn>Cu>Fe. X-ray diffractometric (XRD) analysis proved that the WCo was dominated by quartz, calcite, ettringite, cordierite, diopside and the WG was only dominated by gypsum. The leaching behavior of WG demonstrated pH dependent particularly for the elements of Ca, Mg, Fe, Zn, Cu and Mn but only the elements of Ca and Cr in WCo were shown to be pH dependent in the leaching test. The element of SO4 2from the WG indicated a higher reading than WCo without the influence of pH. Noticeably, the concentration of SO4 2within the WG strongly require regulation and control before it can be utilized as part of raw materials in the production of environmental friendly recycled building materials.

“…Regardless of being a waste patron, construction waste has additionally been outcome into ecological issues in Malaysia [3]. Issues of unlawful dumping have swelled quickly everywhere throughout the nation [16]. There are a lots of construction waste created in the nation because of rapid development in construction industry.…”

“…When looking at them at the country level, it is observed that different countries around the world have been investigated in this regard. Among them, there are (i) European countries such as Netherlands (Bossink & Brouwers, 1996), Greece (Banias, Achillas, Vlachokostas, Moussiopoulos & Papaioannou, 2011), Norway (Bergsdal, Bohne & Brattebo, 2007), Ireland (Kelly & Hanahoe, 2008) (Coelho & de Brito, 2011a,b;De Melo, Goncalves & Martins, 2011;Malia, de Brito, Pinheiro & Bravo, 2013), and Germany (Hoglmeier, Weber-Blaschke & Richter, 2013), (ii) Asian countries such as Hong Kong (Tam, 2008;Jaillon, Poon & Chiang, 2009;Cheng & Ma, 2013;Li & Zhang, 2013), Taiwan (Hsiao, Huang, Yu & Wernick, 2002), Malaysia (Begum, Siwar, Pereira & Jaafar, 2006;Lau, Whyte & Law, 2008;Che Hasan, Yusof, Mohd Ridzuan, Atan, Noordin & Abdul Ghani, 2013;Nagapan, Rahman, Asmi & Adnan, 2013), China (Li, Ding, Mi & Wang, 2013), Japan (Hashimoto, Tanikawa & Moriguchi, 2009), and Thailand (Kofoworola & Gheewala, 2009), (iii) American countries such as the US (Cochran & Townsend, 2010), Canada (Wimalasena, Ruwanpura & Hettiaratchi, 2010), and Brazil (Formoso, Soibelman, De Cesare & Isatto, 2002), (iv) Middle Eastern countries such as Kuwait (Kartam, Al-Mutairi, Al-Ghusain & Al-Humoud, 2004), Palestine (Al-Sari, Al-Khatib, Avraamides & Fatta-Kassinos, 2012), Israel (Katz & Baum, 2011), and Lebanon (Tamraz, Srour & Chehab, 2011), and lastly (v) Australia (McDonald & Smithers, 1998).…”

1280In the current study, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented. Toward this aim, the formation process of the fresh RMC waste in construction projects was first introduced in a detailed manner, together with an in-depth literature review in this specific domain of the construction engineering and management. Then, the measurement procedure of the waste amount or coefficient of the fresh RMC was revealed and discussed as a practical and creative planning knowledge. Hence, a useful and realistic waste management perspective about the cost and potential environmental savings of the RMC waste was drawn. Fresh Ready-Mixed Concrete Waste in Construction Projects IntroductionConstruction wastes not only affect the economy of a country, but also consume natural resources and pollute the environment for a very long term. According to Garvin (2004), 40-50% of the energy produced in the world and 16% of available water resources are consumed to produce construction materials defined as waste. CO2 that appears in the production process of such materials makes up 50% of the total CO2 emission in construction. Given the transportation of these material wastes, this share of 50% likely reaches up to 75%. In this environmental pollution and resource consumption, it should be noted that the cement manufacture plays an important role. In addition, construction wastes occupy large areas by volume. They have a share of approximately 20-40% of the total area occupied by wastes in the US, Canada, Hong Kong, Australia, Japan, and European Union countries (Stokoe, Kwong & Lau, 1999;Kibert, 2000;Poon, 2007). This share can likely increase further if wastes are measured in weight (Mulheron, 1988;Hendriks & Pietersen, 2000). Today, the construction industry tries to deal with enormous amounts of wastes as they are very damaging to the environment. However, it is very hard to assert that the construction industry has generally constituted and improved its waste-based business culture so far. In order to reveal the current position of the construction industry as a whole in terms of types and amounts of construction wastes, it is inevitable that various types of estimates and plans on sub-sectors of the construction industry should be carried out.In this context, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented in the current paper as a part of an on-going research project. This is because, in a reinforced-concrete building project, concrete can have a big share of about 10% of the total project budget (Kazaz, Ulubeyli & Turker, 2004). Of course, these amounts can be single numbers or interval-based values. This decision can be based on a statistical analysis of the real world data. Thus, while preparing their proposals, construction contractors in general and quantity surveyors and cost managers in particular can better estimate the amount and cost of RMC by means of these numeri...
