A slurry distributor comprising: a feed conduit including an entry segment with a feed inlet and a feed entry outlet in fluid communication with the feed inlet , the entry segment extending along a first feed flow axis , the feed conduit including a shaped duct having a bulb portion in fluid communication with the feed entry outlet of the entry segment , the feed conduit including a transition segment in fluid communication with the bulb portion , the transition segment extending along a second feed flow axis , the second feed flow axis being in non-parallel relationship with the first feed flow axis ; and a distribution conduit extending generally along a longitudinal axis and including an entry portion and a distribution outlet in fluid communication with the entry portion , the entry portion in fluid communication with the feed inlet of the feed conduit , the distribution outlet extending a predetermined distance along a transverse axis , the transverse axis being substantially perpendicular to the longitudinal axis ; wherein the bulb portion has an area of expansion with a cross-sectional flow area that is greater than a cross-sectional flow area of an adjacent area upstream from the area of expansion relative to a flow direction from the feed inlet toward the distribution outlet of the distribution conduit , characterized in that the shaped duct has a convex interior surface in confronting relationship with the feed entry outlet of the entry segment , such that a flow of aqueous cementitious slurry moving along the first feed flow axis moves in radial flow in a plane substantially perpendicular to the first feed flow axis . a feed conduit including an entry segment with a feed inlet and a feed entry outlet in fluid communication with the feed inlet , the entry segment extending along a first feed flow axis , the feed conduit including a shaped duct having a bulb portion in fluid communication with the feed entry outlet of the entry segment , the feed conduit including a transition segment in fluid communication with the bulb portion , the transition segment extending along a second feed flow axis , the second feed flow axis being in non-parallel relationship with the first feed flow axis ; and a distribution conduit extending generally along a longitudinal axis and including an entry portion and a distribution outlet in fluid communication with the entry portion , the entry portion in fluid communication with the feed inlet of the feed conduit , the distribution outlet extending a predetermined distance along a transverse axis , the transverse axis being substantially perpendicular to the longitudinal axis ; wherein the bulb portion has an area of expansion with a cross-sectional flow area that is greater than a cross-sectional flow area of an adjacent area upstream from the area of expansion relative to a flow direction from the feed inlet toward the distribution outlet of the distribution conduit , characterized in that the shaped duct has a convex interior surface in confronting relationship with the feed entry outlet of the entry segment , such that a flow of aqueous cementitious slurry moving along the first feed flow axis moves in radial flow in a plane substantially perpendicular to the first feed flow axis . <EOS>
