“…In recent years, the development of LWAs has focused on industrial waste or municipal solid waste as a raw material for reducing the use of natural resources [3][4][5][6][7][8][9][10][11][12]. In other words, industrial waste or municipal solid waste can be reused as a sustainable resource in the manufacturing process of artificial LWAs.…”

Self-consolidating lightweight aggregate concrete (SCLC) is a highly flowable and lightweight concrete. In this study, the properties of SCLC and prestressed SCLC members were tested and compared with those made of normal-weight self-consolidating concrete (SCC). The test results show that SCLC can be used for prestressed concrete members. The use of lightweight aggregates with a particle density larger than 1100 kg/m 3 can avoid the serious segregation of fresh concrete. In addition, the SCLC designed in this study can meet most of the SCC Rank 2 test standards, except for the V-funnel test. The water contained in the lightweight aggregates supplied sustained curing, so the level of drying shrinkage of the SCLC was lower than that of the conventional SCC. However, the level of creep of the SCLC was higher than that of the conventional SCC, because normal-weight aggregates are more able to inhibit the change of the concrete's volume. On-site test results show that after 180 days of prestressing, the prestress loss was about 5.35-6.83% for the full-size SCLC members, which was smaller than that for the conventional SCC members (about 8.19-9.06% loss).

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.
