Workability and Consistency of Fresh Concrete

54-C0195/E
ASTM defines Workability as “the property determining the effort required to manipulate a freshly mixed quantity of concrete with minimum loss of homogeneity”. It reflects the ease and homogeneity of how fresh concrete can be mixed, transported, placed, compacted and finished without segregation. Many factors can affect workability: water content, cement content and type, admixtures, aggregates grading and type.

Slump Cone Test Sets

The slump cone, also known as Abrams cone, is used to measure workability of fresh concrete

Standards AASHTO T119 ASTM C143 EN 12350-2

Portable slump cone test kit 54-C0149/B, 54-C0150/C
Description

 

We propose various sets. Versions 54-C0149/B and 54-C0150/C are particularly suitable for site inspectors as are handy, easy transportable and with housing for all parts.
All cones are seamless and robust. Cones only and components are also available. See accessories and spares.
The slump cone is also known as Abrams cone, from the name of the inventor.

  • Completely electromechanically operated
  • Conforming to EN 12697-33, 5.2 method and ASTM D8079
  • 21” All-in-one touchscreen PC controlled , PC and software included
  • Includes the compaction procedure defined in the brand new EN 12697-33 method 7.3, providing at the beginning a controlled displacement compaction which can grant a flat surface followed by a load compaction phase , which can replicate the real compaction on the road surface
  • Base and foot adjustable heating system available as option
  • Mould dimensions: 500 x 400, 500 x 300, 400 x 300, 300 x 300 and 320 x 260 mm, 195 mm height
  • Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard
  • Vertical balanced of sliding cover for easy access and complete three side view
  • Maximum compaction load 30 kN
  • User defined controlled linear speed up to 300 mm/sec and adjustable pause at the mould inversion point
  • Ideal for producing test beams for 4-Point bending (EN 12697-24, EN 12697-26, AASHTO T321) and slabs down to 38 mm
  • Vibrating roller option, adjustable from 10 to 50 Hz
  • PRO-COMPACT* closed loop control slabs Customization of compacting cycle which can be saved and recalled from the database
*PRO-COMPACT closed-loop is an innovative mechanical and electronic control that combines orthogonality of the load, pendulum motion of the head and sinusoidal non-friction forward-reverse carriage movement. This results in an optimally compacted sample that features Planarity Regularity and hOmogeneity (PRO). The combined load/displacement compaction procedure provides at the beginning of the test a controlled displacement compaction, which can grant a flat surface of the compacted slab, followed by a load compaction phase, which can replicate the real compaction on the road surface.

Vebè Consistometer

This test method is used to measure the consistency of stiff to extremely dry concrete.

Standards EN 12350-3 ASTM C1170 ASTM C1176

54-C0195/E
Description

 

This test method is used to measure the consistency of stiff to extremely dry concrete. Consistency is measured as the time required for a given mass of concrete to be consolidated by vibrating in a cylindrically shaped mould. The small vibrating table operates at a fixed amplitude and frequency.

Versions available:

  • 54-C0195/E conforming to EN 12350-3
  • 54-C0195/C conforming to ASTM C1170 – Procedure A, to ASTM C1170 – Procedure B (using accessory 54-C0195/C1) and to ASTM C1176 (using the accessory 54-C0195/C2)
  • 54-C0195/D conforming to ASTM C1176


The operating principle is practically identical and the units differ from one to the other in the shape of the container and swivel arm with surcharge weight. The 50 lb (22.7 kg) surcharge weight required by ASTM C1170-Procedure A, which is part of the 54-C0195/C unit, can be replaced by the 27,5 lb (12,5 kg) sliding weight to Procedure B and/or by the 20 lb (9 kg) sliding weight conforming to ASTM C1176 (see accessories). Otherwise it’s available the equipment conforming to ASTM C1176 supplied along with 20lb (9kg) surcharge weight. In the EN model the weight of the moving part is 2.75 kg.
