Paper Title
Production of Low-Carbon Construction Components from Industrial Scheduled Wastewater Sludge

This paper investigate the incorporation of industrial scheduled waste in the production of unfired clay brick in supporting Malaysian government agenda on the development of sustainable green construction components. Manufacturing industries produce wastes or secondary products, in which it has a direct impact to the environment. The storage of such wastes remains at the disposal would pollute the air, water resource and agricultural fields. Opportunity for recycling large quantities of wastes to minimize the environmental impact is a mammoth. The aim of this research is to evaluate the engineering and environmental properties of bricks made from waste water treatment (WwTs) and paint sludge (PS) as partial replacement of laterite clay (LC). Clay was combined with industrial waste at 50:50 ratio as target material. These target material were stabilized with hydrated lime (HL) and Portland Cement (PC) on its own and the combination of HL: Ground granulated blast-furnace slag (GgBs) and PC: GgBs both (50:50 and 70:30 ratio) at 30% dosage. Compressive strength, flexural strength, thermal conductivity and toxicity characteristic leaching procedure (TCLP) test were conducted. It was found that it is feasible to utilise WwTs and PS as unfired bricks from the economical and environmental point of view as it will conserve natural resource, protect the environment from waste disposal, and produce a low cost, low carbon construction components towards the government’s enforcement on sustainable green materials.
