Because concrete block and ICF house plans rely on concrete simply for the structural material, which has no bearing on the final form, they lend themselves to a wide range of design aesthetics. Once completed, they are indistinguishable from those using other construction methods – and are significantly more soundproof as well.

Waste of granite dust utilization in ultra-light weight ...

Mainly because granite dust increases W/C ratios and thus mechanical and durability properties tends to decrease. Ultra-light weight concrete, usually has very high W/C ratios, therefore in this type of concrete utilization of granite dust has favourable opportunity. In the research ultra-light weight concrete based on aluminium powder was created.
