Malaysia construction sectoris predicted to grow rapidly for the coming year after experiencing the globalslowdown in year 2008. There is new incentive introduced by the government inthe 11th Malaysian Plan for period time of 2016 to 2020, which aimsto transform the construction industry via four main strategies: Quality,Safety and Professionalism, Environment sustainability, Productivity andInternationalisation (Construction Industry Transformation Programme, CITP,2015). It is developed to address the substantial issues in constructionindustry in term of quality and workmanship and the most essential concern onthe environmental problems which include the high emission of carbon dioxide,construction and demolition waste, solid waste over contribute to landfill andinadequate reliance on the natural resources. The rapid growth of theconstruction industry is indirectly increase the production and consumption forconstruction material manufacturing. The concrete sector is expected to facethe issue related to production such as decline of raw material quality,problem of scarcity and also cost. Aggregate is major components in concretebeside the cement, sand and water where it occupies 70 to 80% of total volumeand will affect the concrete properties. Aggregate or limestone iscommonly used as the construction materials which are obtained from captivemines.
The uses of the granular aggregate are not only need massive naturalstone, but also destroy the ecological environment (Safiuddin et al., 2011). Ifthe aggregate consumption is not control and proper plan, the aggregate willsoon to be depleted (Abdul Rahman et al., 2009). Concurrently, the waste fromthe industrial is identified as the main contributor to the solid waste inMalaysia.
Therefore, in order to conserve the natural resources, there arevarious alternate raw materials generated from industries waste, for exampleslag from steel industry, fly ash from power plant, lime sludge from paperindustry and fertiliser, marble slurry from marble industry and others (NeerajAkhoury, 2017).
