Non-metallic building materials plastic limit measuring instrument calibration specification
1 Scope
This specification is applicable to cement paste standard consistency and setting time measuring instrument, mortar consistency meter, asphalt needle penetration meter,
Calibration of the soil liquid plastic limit tester (hereinafter referred to as the plastic limit tester).
2 Overview
2.1 Cement paste standard consistency and setting time measuring instrument is based on the thixotropy of cement to measure the standard consistency of water
The special measuring instrument for the amount and setting time is to insert the standard consistency cement vertically under the fixed test force by the indenter.
In the case of a fixed time insertion depth or a fixed depth insertion time.
2.2 Mortar consistency meter is a special measuring instrument for measuring the consistency of mortar. It is a fixed test force through a standard cone.
Straight into the depth of the mortar to express.
2.3 Asphalt needle penetration meter is a special measuring instrument for measuring the penetration of asphalt. It is a certain test force through the standard needle.
The depth of the asphalt sample is vertically inserted under time and temperature conditions to express.
2.4 Soil liquid plastic limit measuring instrument is a special measuring instrument for measuring soil liquid plastic limit, which is through a standard cone in a certain
The test force and time are vertically inserted into the depth of the soil sample to express.
3 Measurement characteristics
3.1 Plastic limit tester sliding part quality
The quality requirements for the sliding part of the plastic limit measuring instrument are shown in Table 1.
