Compactadora horizontal IBERTEST para la preparación de probetas de ensayos de resistencia de cementos y morteros
Triple mould EN 196-1 on the jolting table

Jolting table for preparing specimens for strenght testing of cement

Automatic horizontal jolting apparatus (jolting table)

Compaction machine, for preparing moulded specimens (40 x 40.1 x 160 mm) by compacting of the fresh cement mortar in the three-gang moulds.

Horizontal jolting machine is the reference equipment required by the EN 196-1 testing standard for compacting the fresh mortar as an intermediate step when preparing the specimens for flexural and compression strenght test of cements.

The specimen preparing by horizontal compaction is also the reference method for testing other materials such as gypsum, lime, masonry mortars and additives, according to EN 459-2, EN 1744, EN 1015-11, EN 13454-2, etc.

Product Description

General characteristics of the jolting table for cements strength tests

For testing compression strength of cement and mortar , it is necessary to prepare standard test specimens. The test specimens can be prismatic or cubic on depending of the test standards.

European standards specifies that the flexural and compression test must be performed on prisms specimens of 40 x 40 x 160 mm.

For preparing the specimens, defined amounts of cement, water, sand and additives (if any ) must be mixed, and then compacting the resulting mortar into triple-gang moulds.

Following the compacted leave the mortar to cure and harden before demolding. During hardening must avoid dehydration of the specimen, so it should be done under conditions of extreme humidity and controlled temperature.

The empty mould, along with the feed hopper is placed on the table of the jolting table and secured by two fast-action articulated grips. The table surface is properly machined to ensure perfect contact with the base surface of the mould.

The cement mould is then filled with the help of a specified spatulas and compacted in the sequence of operations defined by the standard procedure.

When starting the jolting table, the whole table, mould, hopper and clamping system is lifted by a rotating cam to then drops freely from a height (15.0 ± 0.3 ) mm.

The cam is driven by an electric motor, which sets a uniform rate of 1 revolution per second, giving a rate of 60 drops per minute, according to the test standard.

The table is rigidly attached to a rotating shaft by means of two light and strong arms. The rotation axis is fitted with ball bearings and is conveniently protected from dust and moisture.

In the center of its underside, the table has a rounded surface hammer, ready to strike against a flat top anvil. When the hammer rests on the anvil, the surface of the table is well levelled .

Advantages of the IBERTEST jolting table for testing compressive strength of cements, mortars and other materials.

  • The equipment complies with all the requirements and requirements set by the test standard EN 196-1. IBERTEST can supply a certificate of compliance with all technical requirements required by the test standard .
  • Very robust and reliable equipment that requires no mechanical maintenance.
  • The cam, the hammer and the anvil are wear items due to hit-friction during normal use. When the wear becomes excessive, the user can easily exchange the wear part with new spare ones. IBERTEST always maintains available stocks of the parts you may need.
  • The compaction table surface is also subject to wear and friction of the molds. In the design of the table is provided a removable steel plate, which also can be replaced by a new plate in the event of excessive wear.
  • Security: The IBERTEST horizontal jolting table has, as its main accessory , a soundproof protection cabin. The use of the cabin can attenuate the noise level below 80 dB, according to European health regulations. The soundproofing cabin has an access area through a folding door , allowing the assembly and disassembly of the mold on the table of the compactor .It has a gas spring , located on the side of the door, to facilitate the opening operation and prevent damage if accidentally drops.
  • Safety electrical interlock that prevents operation with the open cabin.
  • The control module is easily interchangeable . If necessary, the module can be easilly replaced by a new one by the user, without aid of the IBERTEST Technical Assistance and with no need for further adjustments.
  • Free choice of operating language : Spanish , English , French and Portuguese.


The compactor , as specified by EN 196-1 , must be securely attached to a concrete block , as a pedestal, seismically isolated from the rest of the pavement.

The entire block base must rest on a rubber sheet of minimum thickness 10 mm and a hardness of 50 ± 5 DIDC ( international grade rubber hardness ), this rubber sheet is available upon request .

To assemble the jolting table on the concrete block, 4 anchor bolts and leveling screws are comprised. For that purpose the machine has 4 tie plates located at its base. 

The assembly is completed by applying a thin layer of cement screed between the plates and concrete block, so as to ensure full contact and the elimination of vibrations.
