    en.wikipedia.org/.../Wave-dissipating_concrete_block

    Tetrapods used to protect a seawall Large interlocked Xblocs (8.0 m 3 or 280 cu ft) in a trial placement. A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties.

    en.wikipedia.org/wiki/Dolos

    A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod . Weighing up to 8 tonnes (8.8 short tons ), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.

    A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).

  5. Cementation (geology) - Wikipedia

    en.wikipedia.org/wiki/Cementation_(geology)

    Calcite cement in an ooid-rich limestone; Carmel Formation, Jurassic of Utah. Minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains ...

  6. Stefan problem - Wikipedia

    en.wikipedia.org/wiki/Stefan_problem

    The classical Stefan problem aims to describe the evolution of the boundary between two phases of a material undergoing a phase change, for example the melting of a solid, such as ice to water. This is accomplished by solving heat equations in both regions, subject to given boundary and initial conditions.

  7. Abrasion (geology) - Wikipedia

    en.wikipedia.org/wiki/Abrasion_(geology)

    Abrasion generally occurs in four ways: [1] [2] glaciation slowly grinds rocks picked up by ice against rock surfaces; [3] solid objects transported in river channels make abrasive surface contact with the bed with ppl in it and walls; objects transported in waves breaking on coastlines; and by wind transporting sand or small stones against ...

  8. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]

  9. Offshore concrete structure - Wikipedia

    en.wikipedia.org/wiki/Offshore_concrete_structure

    Concrete offshore platforms of the gravity-base type are almost always constructed in their vertical attitude. This allows the inshore installation of deck girders and equipment and the later transport of the whole structure to the installation site. The most common concrete designs are: [citation needed] Condeep (with one, two, three or four ...
