摘要： In a process and apparatus for the extrusion of a green body from a paste or suspension of particulate material in a liquid, the suspension is supplied to and substantially fills an extrusion chamber at a relatively low pressure. A high pressure is applied to the suspension on completion of filling whereby the suspension is forced through a moulding spaced with a dewatering section defined by at least partially liquid-permeable walls. A substantial part of the liquid is removed by establishing a pressure differential across at least parts of the wall that are permeable to said liquid, to form a non-flowable shaped body of the particulate material.

摘要： The extrusion of a green body from a paste or suspension of particulate solids in a liquid is conducted by a process which includes the steps of introducing flowable paste or suspension into an inlet end of a moulding passage which is defined by walls having at least one partially liquid-permeable wall section; applying pressure to the paste or suspension, thereby to remove from the passage at least a major portion of the liquid of the paste or suspension, by establishing a pressure differential across the liquid permeable section, so as to form in the passage a non-flowable body of consolidated particulate solids of the paste or suspension, and to extrude the non-flowable body progressively from an outlet end of the passage. The magnitude of the pressure, the rate of removal of liquid and the rate of extrusion are controlled to maintain the non-flowable body at a length which extends back from the outlet end of the passage and across and beyond the liquid-permeable wall section to provide a portion of the body upstream of the liquid-permeable wall section. Liquid is removed from the passage by constant pressure filtration in which liquid being forced from the suspension is filtered through the portion of the non-flowable body maintained upstream of the liquid permeable section.

摘要： Shaped bodies of particulate material are produced by introducing an easily flowable slurry of water and particulate material into a mold with perforated walls and applying a sufficiently high pressure to the slurry in the mold so as to express a sufficient proportion of the liquid to allow physical contact and interengagement between the particles. The extrusion is carried out continuously in an extension process including: (A) introducing the slurry under high pressure, (B) conveying the slurry through a shaping section to (C) a draining and consolidation section with drain holds or slits (3), to leave the extruder through (E) an exit section in the form of a solid body (4).

摘要： A cementitious pipe as a tubular wall of fibre-reinforced cementitious pseudo strain hardening (PSH) matrix. The matrix and a wall thickness to diameter ratio within a range are such that the pipe exhibits characteristic behaviour in diametral quasi-static bending under a 3-edge bearing method. The behaviour is such that a stress versus relative displacement curve for the pipe exhibits a substantially linear elastic region having a first slope within first limits, and from the LOP to the MOR for the pipe, a PSH region which, beyond a possible transition region, has a slope which is less than that of the elastic region and is within second limits.
