    Speed in the construction practices followed in ready mix concrete plant is followed continuously by having mechanized operations. The output obtained from a site mix concrete plant using a 8/12 mixer is 4 to 5 metric cubes per hour which is 30-60 metric cubes per hour in a ready mix concrete plant.

  4. Self-consolidating concrete - Wikipedia

    en.wikipedia.org/wiki/Self-consolidating_concrete

    Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).

    en.wikipedia.org/wiki/Types_of_concrete

    Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material as the aggregate, and often mixed in improvised containers. The ingredients in any particular mix depends on the nature of the application.

    0.75 m³ (1 cubic yard) cart-away mixing trailer. A variant of standard concrete transportation is the concrete (or, cement) mixing trailer. These small versions of transit-mix trucks are used to supply short loads of concrete. They have a concrete mixing drum with a capacity of between 0.76 and 1.34 cubic metres (1 and 1.75 cu yd).

  8. Water–cement ratio - Wikipedia

    en.wikipedia.org/wiki/Water–cement_ratio

    A higher ratio gives a too fluid concrete mix resulting in a too porous hardened concrete of poor quality. Often, the concept also refers to the ratio of water to cementitious materials, w/cm. Cementitious materials include cement and supplementary cementitious materials such as ground granulated blast-furnace slag (GGBFS), fly ash (FA), silica ...

  9. Concrete densifier - Wikipedia

    en.wikipedia.org/wiki/Concrete_densifier

    A concrete densifier is a chemical hardener that penetrates the concrete surface, reacting with the material to form crystals that fill the pores and increase surface density. This process significantly improves the concrete's resistance to wear, dusting, and chemical damage.
