  2. Brick - Wikipedia

    en.wikipedia.org/wiki/Brick

    The density of solid clay bricks is around 2000 kg/m 3: this is reduced by frogging, hollow bricks, and so on, but aerated autoclaved concrete, even as a solid brick, can have densities in the range of 450–850 kg/m 3. Bricks may also be classified as solid (less than 25% perforations by volume, although the brick may be "frogged," having ...

  3. Kilogram per cubic metre - Wikipedia

    en.wikipedia.org/wiki/Kilogram_per_cubic_metre

    The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]

  5. Gravel - Wikipedia

    en.wikipedia.org/wiki/Gravel

    ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm (0.079–0.248 in) for fine and 20–63 mm (0.79–2.48 in) for coarse. One cubic metre of gravel typically weighs about 1,800 kg (4,000 lb), or one cubic yard weighs about 3,000 lb (1,400 kg). Gravel is an important commercial product, with a number of applications.

  6. Types of concrete - Wikipedia

    en.wikipedia.org/wiki/Types_of_concrete

    The variable density is normally described in kg per m 3, where regular concrete is 2400 kg/m 3. Variable density can be as low as 300 kg/m 3 , [ 18 ] although at this density it would have no structural integrity at all and would function as a filler or insulation use only.

  7. Baumé scale - Wikipedia

    en.wikipedia.org/wiki/Baumé_scale

    The Baumé scale is a pair of hydrometer scales developed by French pharmacist Antoine Baumé in 1768 to measure density of various liquids. The unit of the Baumé scale has been notated variously as degrees Baumé, B°, Bé° and simply Baumé (the accent is not always present). One scale measures the density of liquids heavier than water and ...

    Instead the formula that would fit some of the Bonales data is k ≈ 2.0526 - 0.0176TC and not k = -0.0176 + 2.0526T as they say on page S615 and also the values they posted for Alexiades and Solomon do not fit the other formula that they posted on table 1 on page S611 and the formula that would fit over there is k = 2.18 - 0.01365TC and not k ...

  9. Specific surface area - Wikipedia

    en.wikipedia.org/wiki/Specific_surface_area

    Specific surface area (SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, [1] (with units of m 2 /kg or m 2 /g). Alternatively, it may be defined as SA per solid or bulk volume [2] [3] (units of m 2 /m 3 or m −1).
