- Conforming to NT Build 427 (Scandinavian NORDTEST method)
DESCRIZIONE GENERALE
DESCRIZIONE GENERALE
This method, very popular in Scandinavia, is used for mix design and quality control mainly in concrete products plants, where low workable and zero slump concrete is used (for such products as hollow-core slabs, tubes and paving blocks).
The method is used for: mix design simulating selected production processes specimen preparation for strength test (fresh and cured) research of mix related phenomena (workability, curing time, admixtures etc.).
The compaction of the specimen is achieved by the simultaneous action of a low static compression , and of the shearing action resulting of the motion of the centerline of the test piece, which generates a conical surface of revolution, while the end of the test piece remain approximately perpendicular to the axis of the conical surface.
The machine is pneumatically operated.
The machines are supplied complete with one 100 mm dia. mould, accessories to perform the test and WIN-ICT software for the machine control, data acquisition and compaction curve processing and Excel Macro for gyratory compaction test complete of data processing: PC not included.
