ARTIFICIAL LIGHTWEIGHT AGGREGATE PRODUCTION

2020-2-6  Artificial lightweight aggregate production was involved basically collection of raw materials, paste of ash and cement, molds of different thickness & different sizes of wire mash for slicing the paste. The size of aggregates are depends on laboratory test, so aggregates were made of two sizes of 1/2” and 3/4". Ordinary Portland cement was mixed with rice husk ash according to volume. Paste was placed in mould of 1’x1’x0.5” and 1’x1’x0.75”. The paste was sliced by wire mashes into small pieces using hand pressure after casting to initial setting time. After hardening, aggregates
