Abstract

Disposal of industrial waste is a major concern all over the world due to stringent laws enforced by government agencies. This has motivated many researchers to recycle these wastes into an innovative construction material. Presently, these wastes are recycled to some extent, however the majority of them disposed to landfill. Thus, leading to environmental issues. Similarly, industrial waste, such as spent catalyst and waste papers are hardly recycled in Oman. The present paper discusses the study carried out on Masonry Blocks (MB) fabricated using spent catalyst, lime and waste paper sludge. MB-1 block consists of lime and waste paper sludge as filler material, whereas spent catalyst and waste paper sludge is used in the MB-2 block. For both masonry bocks ordinary Portland cement is used as binder. Laboratory investigation carried out in the material testing laboratory at Caledonian College of Engineering in terms of compressive strength, creep, alternate wetting and drying and thermal conductivity test, revealed that blocks fabricated with spent catalyst showed better performance compared to blocks fabricated with lime.
