Instruction

This instrument is manufactured according to ISO9597-1989, and is used to test the standard consistency of cement. volume stability due to water volume, setting time and free calcium oxide.

Technical Parameter

1. Total weight of sliding part: 300+1g
2. The maximum stroke of the sliding part: 70mm
3. Dimensions (Lx Wx H): 170X110X 300mm
4. Net weight: 3.7Kg

Structure and Function

The main body of the instrument is connected by a bracket and a base. The upper part of the bracket is machined with two concentric smooth holes with a diameter of 12mm to ensure that the sliding part can descend vertically during the test.

The effective length of the test rod for standard consistency determination is 50mm±1mm, and the diameter is φ10mm±0.05mm. The effective length of the test needle for determining the coagulation time is 50±1mm. The effective length of the final coagulation needle is 30mm±1mm, and the diameter of the test needle is φ 1.13mm±0.05mm, the cone test mold for holding cement is 40mm±0.2mm deep, the top inner diameter is φ65±0.3mm, the bottom inner diameter is φ75±0.5mm, the test mold is equipped with a larger than the test mold, and the thickness is > 2. 5mm flat glass bottom plate. The sliding part can fall freely by gravity in the bracket hole of the Vicat instrument, and there should be no tightness or looseness.
