Effect of Raw Material Ratios on the Compressive Strength of Chang Jiang Iron Ore Gangues Aerated Concrete Block

Abstract:

The present study was to investigate the production of aerated concrete block from ChangJiang iron ore gangues. Analyze Quartz Sand, cement, CaO and gangue’s ratio’s influence on the aerated concrete block’s compressive strength, and then determine the optimum ratio. The results shows that gangue, quartz sand, cement, CaO, gypsum, aluminum powder, additive’s optimum ratio is 60.11%，8.26%，15.03%, 14.07%, 2%, 0.06% and 0.07% the dry weight of raw materials. Obtain the strongest compressive strength with the ratio 0.59:1 for water and raw materials. Adding iron gangues into aerated concrete block can turn wastes into treasures, which is originally done by us.
