Abstract
The reuse of industrial waste plays a crucial role in avoiding environmental impacts caused by incorrect disposal. The industrial production commonly generates huge volumes of wastes and also, increase costs associated to waste management and landfills maintenance. This study investigates the reuse of Grits waste, from cellulose kraft industry, as filler on gypsum plaster. The samples were prepared in proportions of 100/0, 85/15, 75/25 and 50/50 Gypsum/Grits and, tested at 7, 14, 21, 28 days. The mechanical resistance with incorporation until 25wt% of Grits as filler is over than the regulatory standards recommendations. Flexural and compression strength tests for 15wt% of gypsum replaced achieving 4.5 MPa and 8.3 MPa, respectively. The manufacture of Gypsum/Grits became a viable solution for waste management and, has a great potential of enabling fabrication of gypsum plaster board, a low cost and more sustainable new material.
期刊介绍：
Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
