ALC/AAC panels are normally made of silicon sand, cement, calcium lime, gypsum and small quantities of aluminium. Using steam and high pressure, numerous air holes are produced in the panel which is then reinforced with anti-corrosion steel bars. ALC/AAC blocks are also manufactured with the same process without the anti corrosion steel bars.
By using computerised software to accurately control the production process which involves mixing the raw material, processing the anti-corrosive steel bars, organising the material into frames, pouring the paste, cutting, steaming, pressing and surface processing, this innovative building materials impressive performance capabilities is augmented. This is paired with a stringent quality control process to optimise results.
When the forms are removed, the foam like material is stabile but soft enough to be wire cut. This can be done in pre-specified shapes of blocks or panels and then moved into the autoclave chamber for eight to fourteen hours. The final chemical hydro thermal reaction is initiated by the steam pressure process. At 180 Centigrade and a pressure of 12 bars, the quartz sand reacts with the calcium hydroxide to give by-product that gives ALC/AAC its high strength properties. Post autoclaving, the material has only to be shrink wrapped in plastic to be ready for immediate delivery onto the construction site.
Based on customer requirements, decorative patterns can be made on the autoclaved panels post treatment.
All panels are subjected to strict quality checks prior to delivery to customers
