“…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).

Abstract:In view of increasing concerns over nonrenewable resource depletion and waste management, this study aimed to apply the Taguchi optimization technique to determine the process conditions for producing bricks by incorporating thin-film transition liquid crystal display (TFT-LCD) waste glass powder with reservoir sediments. An orthogonal array L 16 (4 5 ) was adopted, which consisted of five controllable four-level factors (i.e., cullet content, drying method, preheat time, sintering temperature, and error). Moreover, the analysis of variance method was used to explore the effects of the experimental factors on the density, water absorption, shrinkage ratio, loss on ignition, porosity, and compressive strength of the fired bricks. The microstructures of the fired specimens were investigated by scanning electron microscopy. Then, large-scale production techniques for fired bricks containing recycled TFT-LCD glass cullet and reservoir sediments were developed in a commercially available tunnel kiln. The test results showed that the structure of the fired specimen was loose at a sintering temperature ranging from 900 to 950 • C. However, the fired specimen showed a significant densification at the sintering temperature of 1050 • C. In addition, the Taguchi method was found to be a feasible approach for optimizing the process condition of bricks using recycled TFT-LCD glass cullet and reservoir sediments and it significantly reduced the number of tests. Further, the characteristics of fired bricks developed in the tunnel kiln were in compliance with Chinese National Standards class I building bricks criteria.
