Definition - What does Cast-In-Place Concrete mean?
Cast-in-place concrete is construction material that uses a temporary form to shape the concrete slurry until it hardens. It has been used in housing construction for over 100 years, and has been used in traditional open-trench pipeline construction. Cast-in-place concrete is also used in the manufacture of concrete pipes used in the trenchless construction industry.
Trenchlesspedia explains Cast-In-Place Concrete
Cast-in-place, also known as poured-in-place, concrete is another way of saying that some form is being used to shape the semi-liquid material. Thomas Edison championed the use of removable forms in the construction of concrete houses. The technique was predominately used for the casting of basement walls using low-grade material, but Edison built several prototypes that remain standing today.
Cast-in-place concrete pipes (CIPCP) have been used in many different settings, including monolithic concrete irrigation pipe. The authors of a 1994 paper on the subject, Charles M. Burt and John M. Wegener, explain how CIPCP was used as early as 1922 in the Turlock Irrigation District of California. It is considered a low-cost alternative to other forms of piping.
Trenchless technology is being used in the rehabilitation of much of this older pipe. Methods such as sliplining can significantly prolong the lives of concrete pipes without replacement. Newer methods of cast-in-place concrete installation include the use of machines that use centrifugal force to blast concrete onto the walls of existing metal pipes.
