Abstract
A slurry distributor (S) for distributing a low viscosity fluid into a viscous, hydraulic slurry comprises a main conduit (1) located on a first axis .alpha. for conducting a flowing, viscous, hydraulic slurry towards an orifice (3). The distributor (S) has an air injector (5) defined by a stem (7) located on a second axis .beta.. The air injector (5) is for introducing air into the slurry to disperse it from the orifice (3). A second injector (9) located on a third axis .gamma. and intersecting the main conduit (1) is used to introduce a low viscosity liquid, preferably an accelerator, into the flowing slurry such that the low viscosity liquid impinges on the air injector stem (7) before dispersion. The distributor is especially useful with fireproofing compositions since it provides effective distribution of a viscous, hydraulic, cementitious slurry with an acidic accelerator.
