Foam concrete is produced by mixing cement or fly ash, sand, water, and a synthetic aerated foam, which provides stability to the air bubbles, in contrast to air-entrained concrete which is produced incorporating specialized admixtures directly into the concrete mix. Foam concrete offers excellent thermal and acoustic insulation properties ...
Concrete plant showing a concrete mixer being filled from ingredient silos Concrete mixing plant in Birmingham, Alabama, in 1936 Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete.
This is often referred to as on-site concrete, site mixed concrete or mobile mix concrete. This is a mobile miniaturized version of the large stationary batch plant. They are used to provide ready mix concrete utilizing a continuous batching process or metered concrete system.
The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed.All things being equal, concrete with a lower water-cement (cementitious) ratio makes a stronger concrete than that with a higher ratio.

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).
When water is mixed with portland cement, the product sets in a few hours and hardens over a period of weeks. These processes can vary widely, depending upon the mix used and the conditions of curing of the product, [18] but a typical concrete sets in about 6 hours and develops a compressive strength of 8 MPa in 24 hours. The strength rises to ...
