Dec 16, 2019· Lightweight aggregates are aggregates whose maximum dry loose bulk density is about 880kg/m3 for course aggregates and 1040Kg/m3 for all-in aggregates. Lightweight aggregates are classified as natural and artificial depending on how they are secured. The main natural lightweight aggregates are diatomite, pumice, scoria, volcanic cinder, and tuff.

The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate. When the complete aggregate is replaced with lightweight aggregate, the weight decreases the concrete density of by approx. 10 kilogram per cubic meter. For Example, 1 square foot of 1.5-inch thick normal concrete weighs about 18 pounds.

Dec 16, 2019· Lightweight aggregates are classified as natural and artificial depending on how they are secured. The main natural lightweight aggregates are diatomite, pumice, scoria, volcanic cinder, and tuff. Except for diatomite, all are volcanic in origin. Pumice and scoria are more widely used for hollow and solid concrete block production in Ethiopia.
