  2. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    Suppose the same iron block is reshaped into a bowl. It still weighs 1 ton, but when it is put in water, it displaces a greater volume of water than when it was a block. The deeper the iron bowl is immersed, the more water it displaces, and the greater the buoyant force acting on it. When the buoyant force equals 1 ton, it will sink no farther.

  3. Displacement (fluid) - Wikipedia

    en.wikipedia.org/wiki/Displacement_(fluid)

    The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. [2] The weight of the displaced fluid can be found mathematically. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV.

  4. Xbloc - Wikipedia

    en.wikipedia.org/wiki/Xbloc

    Large Xblocs (8.0 m 3 or 280 cu ft) on a trial placement area. An Xbloc is a wave-dissipating concrete block (or "armour unit") designed to protect shores, harbour walls, seawalls, breakwaters and other coastal structures from the direct impact of incoming waves.

  5. Here’s Why You Shouldn’t Use Salt on Concrete - AOL

    Michigan Concrete Association recommends a regular salt like Morton table salt instead of an ice melter because it’s 100 percent sodium chloride (NaCl). This, however, is recommended for ...

  6. Superplasticizer - Wikipedia

    en.wikipedia.org/wiki/Superplasticizer

    Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete. [1]

  7. Permeable paving - Wikipedia

    en.wikipedia.org/wiki/Permeable_paving

    Permeable paving systems, specifically pervious concrete pavers, have shown significant cost benefits after a Life Cycle Assessment was performed, as the reduction in total weight of material needed for each unit is reduced by nature of the porous design. [21]

  8. Tetrapod (structure) - Wikipedia

    en.wikipedia.org/wiki/Tetrapod_(structure)

    A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...

    "The majority of the adult body is water, up to 60% of your weight," says Schnoll-Sussman, adding that the average person's weight can fluctuate one to five pounds per day due to water.
