What is the density of Cement, Fly ash,20 mm aggregate, 10 mm aggregate and stone dust?

Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume It depends on the packing of aggregate ie Either loosely packed aggregates or well dense compacted aggregates

According to the USGS in 2006, 29 million tonnes of Portland cement concrete (including aggregate) worth $219 million was recycled, and 16 million tonnes of asphalt concrete (including aggregate) worth $118 million was recycled, both by crushed stone operations Much more of both materials are recycled by construction and demolition firms not in the USGS survey

The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used Lightweight concrete has a density of 115 lbs per square foot

Point Should Be Know Before Estimating Density of Cement = 1440 kg/m3 Sand Density = 1450-1500 kg/m3 Density of Aggregate = 1450-1550 kg/m3 How many KG in 1 bag of cement = 50 kg Cement quantity in litres in 1 bag of cement = 347 litres 1 Bag of cement in cubic metres = 00347 cubic meter
