“…Most of the construction aggregates (Table 1) still come from primary natural resources-natural sands and gravels, or crushed stone aggregates (Poulin et al 1994;Smith and Collis 2001), although importance of secondary sources (industrial by-products or wastes, manufactured aggregates, construction and demolition wastes) is rapidly increasing (De Mulder 1984). Each type of aggregate has certain advantages but also many disadvantages (Table 2) which are not solely related to their properties and performance in use but also to other factors such as impact on the environment.…”

“…Also, in the Southern and Southeast regions, many cities located in the Paraná sedimentary basin require the transportation of coarse aggregates over distances greater than 100 km [15]. Globally, the scarcity of aggregates due to geological restrictions was also observed in the Netherlands [18], and in the central region of United States [19].…”

Due to the scarcity of crystalline massifs in the north of Brazil, concrete producers have been using crushed stone and cement from suppliers located hundreds of kilometers away. In this case, CO2 emissions related to material transportation for concrete production may become significant. Thus, this study aims to analyze the influence of the transportation of the materials in CO2 emissions of ready-mix concrete production in Rio Branco (Acre). Concrete compositions were obtained from a local concrete producer. Brazilian methods of dosage were not applicable due to the high fineness of the regional sand available; the mix designs were adjusted empirically. Two types of cement (CP V-ARI and CP IV) were considered to create the studied scenarios. Transportation distances of the raw materials (cement and aggregates) ranged from 20 km (local sand supplier) to 3,592 km (cement supplier from Sete Lagoas, MG). CO2 emissions to produce concrete (fck of 25 MPa, cement consumption of 426 kg/m3) ranged from 208 kgCO2/m3 to 573 kgCO2/m3. Transportation was responsible for up to 20% of total emissions. The emissions in this study are considerably higher than the national data of concrete production available in the Construction Environmental Performance Information System (Sidac) due to the higher cement consumption and higher transportation distances. Although cement consumption in Acre represents less than 1% of Brazilian consumption, the results reveal the impact of transportation distances in CO2 emissions of concrete in cities that deal with local scarcity.
