“…Some of these wastes have great reutilization potential; as a result, in the last decade, some investigations into the use of this type of waste have been conducted, and most studied paper industry wastes in road construction (Modolo et al, 2010), the manufacture of ceramic materials (Warpechowski da Silva et al, 1998), interior coatings and acoustic bricks (Wolff et al, 2015),forestry and the horticulture (Cabral et al, 2008) and biogas production for the road transport sector (Larsson et al, 2015).…”

“…In this regard, the research performed in Portugal by Modolo et al (2010) is unique in that it analysed the possibility of using green liquor dregs as a partial substitute for natural aggregate. These researchers concluded that the dregs must be subjected to a pretreatment (drying at 105 °C and subsequent washing with distilled water at 70 °C for periods of 10 minutes) to ensure that the mixtures have suitable water resistance.…”

“…In recent years, different methods have been evaluated to solve the wastes problems (Treloar et al 2003;Hınıslıoglu and Agar 2004;Modolo et al 2010;Sutcu and Akkurt 2010;Raut et al 2012;Tan et al 2013;Yeheyis et al 2013). These researches have laid a well foundation for recycling municipal and industrial wastes.…”

Population growth and increasing demand for industrial enterprises such as pulp and paper production lead to environmental problems such as over-exploitation of resources and pollution of soil, air and water. Thus, for the importance of reducing the negative effects of incineration and landfilling of wastes for the protection of environment, two kinds of recycled paperboard mill wastes were used as partial replacement of sand (volume percentage), to produce non-load-bearing lightweight concrete. Waste type 1 consists of paperboard chips mixed with small amount of sand, and waste type 2 consists of paperboard chips mixed with expanded polystyrene and nylon. This study was carried out in laboratory scale to achieve acceptable strength and minimum density by using maximum amount of waste, in accordance with ASTM-C129 for non-load-bearing lightweight concrete construction. Therefore, three types of concrete, including concrete containing waste type 1 (replacing 0, 60, 70 and 80 % of waste and sand), concrete containing waste type 2 (replacing 0, 55, 75 and 95 % of waste and sand) and concrete containing both waste types, were constructed. Different tests on the fresh and hardened concrete, including slump, pH, oven-dry density, compressive and tensile strengths, flexural strength, flexural toughness and water absorption, were carried out. The results indicate that the use of waste type 1 is more reliable than waste type 2 in terms of concrete specifications and standard-conforming viewpoints. Results revealed that use of these wastes in concrete can save the paperboard industry disposal costs and produce 'greener concrete' for construction.

“…For this reason, it is necessary to find viable alternative technologies for the final disposal of this solid waste material. Different alternative methods for the final disposal of grits waste from the cellulose industry were tested, including agriculture, road paving, red ceramic, and cement clinker production [5][6][7][8]. The reuse of grits waste for production of soil-cement bricks has been also suggested [3,4,9].…”

In the cellulose industry the Kraft process is widely used to produce cellulose. This process generates huge volumes of inorganic solid wastes, including the grits waste. In Brazil, the final disposal of this solid waste is of high economical and environmental interest. The present work assesses the influence of the addition of grits waste on the densification behavior of soil-cement bricks. The raw materials used were soil, Portland cement, and grits waste. Soil-cement bricks containing up to 30 wt.% grits waste in partial replacement of Portland cement were prepared by uniaxial pressing and cured for 28 days. The following technological properties were determined: water absorption, compressive strength, and durability. The microstructure was evaluated by scanning electron microscopy and X-ray diffraction. The experimental results indicated that the addition of grits waste influenced positively the densification behavior of the soil-cement bricks. Moreover, the grits waste could be incorporated into the soil-cement brick composition up to 20 wt.% as a partial replacement of Portland cement. Keywords:grits waste, soil-cement brick, densification, microstructure. Resumo
