Abstract
A foam injection system for use in the manufacture of cementitious products includes a foam injection body and first and second port inserts. The foam injection body defines a slurry passageway and a port passageway having a port opening in fluid communication with the slurry passageway. The first and second port inserts respectively define first and second foam passageways having first and second orifice sizes. The first and second orifice sizes are different. The first and second port inserts are adapted to removably mount to the foam injection body such that the respective foam passageway is in fluid communication with the slurry passageway via the port opening of the port passageway. One port insert can be replaced with another to readily vary the pressure of the foam passing through the particular port insert and injected into a cementitious slurry traveling through the slurry passageway.
