This work is part of a broad research conducted to study the re-use of industrial wastes in an economical and environmentally sustainable manner. Re-use of lightweight ash from the paper mill industry in the manufacture of plaster blends is examined in this study. Lightweight ash is produced during the combustion process of de-inking sludge. Studies demonstrate that lightweight ash is an excellent ingredient in the production of cement mortars and/or pozzolanic mortars to be used as plaster. In this research, ash valorization was researched by investigating the efficacy of the ash as it is, as a substitute for very fine sand.If properly mixed at an optimal mix proportion, the mechanical strength ranges from 4÷10MPa with specific gravity between 1150 and 1350 Kg/m 3 . Water absorption may be reduced to a very low level with silane-based surface treatment.

“…This is in contrast to previous research which has used commercial EPS spheres rather than waste EPS. In addition, up to 80% by mass of Portland cement was replaced by PSA, whereas in previous research only up to 20% of cement was replaced by PSA (49,50).…”

The objective of this research was to develop lightweight cement mortars with good thermal-insulation properties by incorporating expanded polystyrene (EPS) and paper sludge ash (PSA), both of which are problematic waste materials. The mortars formed had low thermal conductivity and low bulk density compared to control samples. Ground EPS produced lower thermal conductivity samples than powdered EPS. Resource efficient mortars containing up to 20% PSA, and 60% of EPS are considered suitable for use in rendering and plastering applications.

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.
