Different chemical binders have been developed through research to combine emulsions of ash particles (fly ash), similar materials and recycled polystyrene to provide a product that guarantees the homogeneity on micro and macroscopic levels. The system is based on the SASFA code of practice for Steel Framed Buildings. This entail
s the use of a galvanized steel lip channel of a gauge of 0.58mm or 0.8mm, and of a profile of 90mm x 30mm x 10mm. The walling design constitutes a panel with a 60%/40% cement and waste ash or waste slag mixture. On a “per house” basis a total of 25 tons less cement is used in construction. Commercialization of this technology entails the establishment of a panel manufacturing entity that has a capacity to roll-out panels on a daily basis. The panels are then transported to a location for walling assembly for a fit-for-purpose house. Once the building plans for the project are received, our technical team converts the plans to light steel frame plans, where the steel frames are rolled and formed accordingly under strict control and supervision from the necessary qualified people. The mixture then gets casted into the light steel frame panels. The paste core has a density of 300kgs –450kgs per cubic meter, most preferably at 420kgs per cubic meter. The paste is stabilized by polymers and the use of synthetic fibers. The paste is then poured into the core of the panels in which it is gripped by the lip channel profiles. The paste is levelled. This is done in multi-stack configurations. In the case of Portland cement the panels would remain in the stack for 24 hours before being bulk stacked to allow hydration to continue at a duration of 7 days. This monolithic structural panel is now ready for dispatch on flatbed trucks with a rigging capacity. This technology is logistically so efficient that panels equivalent to three 62m houses can be loaded on a super link truck and transported to site. Site assembly is into steel floor runners, the panels being cleated on both sides in three positions, top, middle and bottom. A ring beam is then applied over the top of the panels and the roof is fixed to pre-located brackets. Wall panel assembly is complete in 6 hours for a 62m² house.
