  2. Water reducer - Wikipedia

    en.wikipedia.org/wiki/Water_reducer

    These inexpensive products were derived from wood and paper industry, but are now advantageously replaced by other synthetic sulfonate and polycarboxylate, also known as superplasticizers. Water reducers offer several advantages in their use, listed below: reduces the water content by 5-10%; decreases the concrete porosity

  3. Superplasticizer - Wikipedia

    en.wikipedia.org/wiki/Superplasticizer

    Superplasticizers (SPs), also known as high range water reducers, are additives used for making high-strength concrete or to place self-compacting concrete. 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.

  4. Vitrified clay pipe - Wikipedia

    en.wikipedia.org/wiki/Vitrified_clay_pipe

    Bell & Spigot Pipe manufactured in the U.S. going into the trench Glazed ceramic pipes, manufactured in the EU. Vitrified clay pipe (VCP) is pipe made from a blend of clay and shale that has been subjected to high temperature to achieve vitrification, which results in a hard, inert ceramic.

  5. Permeable paving - Wikipedia

    en.wikipedia.org/wiki/Permeable_paving

    Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below. In ...

  6. Concrete sealer - Wikipedia

    en.wikipedia.org/wiki/Concrete_sealer

    Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.

  7. Gypsum concrete - Wikipedia

    en.wikipedia.org/wiki/Gypsum_concrete

    Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...

  8. Superplasticity - Wikipedia

    en.wikipedia.org/wiki/Superplasticity

    Just like other superplastic materials, the strain rate sensitivity m is larger than 0.3, indicating good resistance against local necking phenomenon. A few aluminium alloy composites such as 6061 series and 2024 series have shown high strain rate superplasticity, which happens in a much higher strain rate regime than other superplastic ...

    en.wikipedia.org/wiki/Dibutyl_phthalate

    The use of this substance in cosmetics, including nail polishes, is banned in the European Union under Directive 76/768/EEC 1976. [13]The use of DBP has been restricted in the European Union for use in children's toys since 1999.
