High-volume fly ash mortar is considered a "green" material, a sustainable development solution for the construction industry, in which the fly ash replacement Portland cement content is over 50%. However, this material has the major disadvantage of slow strength development, especially at an early age, which limits its applicability.

Supply chain management literature suggests that there are many mutually dependent points in the supply chain and each supply chain point is sensitive to the performance of one another. In the course of business, interrelated supply chain activities might get destabilized because of the manmade or natural factors.

This research focuses on Fibre Cement Felts (FCF), which is a non-woven textile substrate acting as a conveyor belt for the manufacturing of Fibre Cement Sheets (FCS). Fibre Cement Felts are a valued component required in the manufacturing process of Fibre Cement Sheets, used in construction for today’s building industry. Identifying the key factors that most influence FCF will assist in understanding of the relationship between fibre diameters, carded web, and mechanical bonding.

The reactions form chains and rings of alumino-silicate networks in geopolymeric structures. The raw materials used for geopolymerization normally contain high SiO2 and Al2O3 in the chemical compositions such as meta-kaoline, rice husk ash, fly ash, bottom ash, blast furnace slag, red mud, and others. The geopolymer-based material has potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost as it utilizes industrial waste resources.
