  2. Creep and shrinkage of concrete - Wikipedia

    en.wikipedia.org/.../Creep_and_shrinkage_of_concrete

    Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.

  3. Concrete leveling - Wikipedia

    en.wikipedia.org/wiki/Concrete_leveling

    In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.

  4. Grout - Wikipedia

    en.wikipedia.org/wiki/Grout

    Grout is generally a mixture of water, cement, and sand, and it frequently gets employed in efforts such as pressure grouting, embedding rebar in masonry walls, connecting sections of precast concrete, filling voids, and sealing joints such as those between tiles. Common uses for grout in the household include filling in tiles of shower floors ...

  5. 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]

  6. Ready-mix concrete - Wikipedia

    en.wikipedia.org/wiki/Ready-mix_concrete

    This type of truck delivers concrete in a plastic state to the site. [2] The second is the volumetric concrete mixer. This delivers the ready mix in a dry state and then mixes the concrete on site. However, other sources divide the material into three types: Transit Mix, Central Mix or Shrink Mix concrete. [3] [4]

  7. Pressure grouting - Wikipedia

    en.wikipedia.org/wiki/Pressure_grouting

    Since first usage in the 19th century, grouting has been performed on the foundation of virtually every one of the world's large dams, in order to reduce the amount of leakage through the rock, and sometimes to strengthen the foundation to support the weight of the overlying structure, be it of concrete, earth, or rock fill. There are four ...

    en.wikipedia.org/wiki/Dipstick

    The instrument is used in 66 countries on six continents to measure the flatness and levelness of concrete floor slabs and pavements. [3] [4] The Dipstick measures concrete floor slab flatness/levelness in terms of Face Floor Profile Numbers ("F-Numbers"), a profile measurement system adopted in 1990 by the American Concrete Institute.
