Abstract

Disposal of Iron ore tailings is one of the major problems in mining industry. Investigations are being done all over the world to utilize tailings for useful purposes. The scope of this work was to study the utilization of iron ore tailings in manufacture of stabilized compressed building bricks. For two types of sand like Natural sand and artificial sand, two sets of mix proportion (Mix1 and Mix2) were prepared based on the properties of iron ore tailings for the addition of various percentage of cement. Totally sixty stabilized compressed building bricks were prepared for each type of mix, all the o specimens were cured by steam using steam curing tank for 8 hours at 100 C and Laboratory tests were conducted for Density test, Dry compressive strength, Wet compressive strength, Initial rate of absorption, Water absorption, Efflorescence test, Falling test, Dimensionality test, Soundness test, and Hardness test. Finally results were tabulated for the comparison of results of each mix ratios. In all the comparisons, compressive strength of bricks made by tailing based mix was higher than the IS standard specification of conventional bricks. Similar trend was in other laboratory tests also.
