How much is a cubic meter of mechanically broken concrete

Ask the Physicist!

Rubber on wet asphalt has a range of possible μ=0.25-0.75 with a corresponding range of speeds v=27-47 mph. Rubber on wet concrete has a range of possible μ=0.45-0.75 with a corresponding range of speeds v=37-47 mph.

CHAPTER 7: BRIDGE MAINTENANCE

The efficiency of the dustless power tool system was verified by air sampling results of two to three micrograms per cubic meter, far below both OSHA''s Permissible Exposure Limit of 50 micrograms per cubic meter and the action level of 30 micrograms per cubic meter per eight-hour exposure limits.([liii])

Ask the Physicist!

Then, in 1983, the meter was redefined again, but now as the distance which light travels in 1/299,792,458 seconds; you see that what this definition does is to set the speed of light to be 299,792,458 meters/second in our system of units and tailor the length of the meter to agree.

Density and density measurement :: Anton Paar Wiki

The most frequent density unit is kilogram per cubic meter (kg/m³), used in petrochemistry, for example. In other industries, density is reported in gram per cubic centimeter (g/cm³). The conversion factor in this case is 1000 (1 g/cm³ = 1000 kg/m³).
