Verification method:
Appearance inspection: Items a, b, and c in the technical requirements shall be inspected visually and manually.
Use a balance to weigh the total mass of the test cone and sliding rod.
Use a vernier caliper to measure the size of the test cone and the size of the conical metal cylinder.
Use a universal angle ruler to measure the deviation of the test cone.

Maintenance and upkeep:
When storing or using the standard cone, strict protection should be taken to avoid damaging the outer cone surface and cone * of the standard cone.
After the completion of the experiment, the instrument should be cleaned and coated with anti rust grease.
Store the instrument with a cover when not in use.

Structure:
The instrument mainly consists of a chassis, a bracket, a digital ruler, a standard test cone (with a scale), and a container for storing materials.
The chassis and pillars are connected together using keys, spring washers, and nuts. The horizontal arm is controlled by two fastening screws to slide up and down on the column, and the scale moves on top of it. Loosen the left fastening screw on the column, the cross arm can move up and down, and then fix it in the desired position. The digital ruler can be zeroed at any position, and the vertical depth of the standard cone can be directly read on the ruler.

Introduction:
Widely used in construction sites, highway bureaus, quality supervision bureaus, research institutions and other testing and research units. Used to determine the flowability of mortar (generally referred to as consistency), the consistency of mortar is represented by the number of centimeters that a standard cone with a certain geometric shape and weight can freely sink into the mortar mixture under its own weight.

Parameters:
Depth of immersion: 0-14.5 centimeters.
△ Sinking volume: 0-229.3 cubic centimeters.
△ Small scale value (sinking depth): 1 millimeter.
Cone angle: 30 °.
△ Height: 145 millimeters.
△ Cone seat diameter: 77.72 millimeters.
The combined weight of the cone and sliding rod is 300 ± 2 grams.
△ Dimensions: 360 × 300 × 920.

Technical requirements:
The gear rack that drives the dial should be clean and free from deformation.
The position of the dial is fixed, and the scale lines should be clear and free of deformation.
The sliding rod and test cone surface should be straight and smooth, and fall freely by their own weight without any tightness or looseness.
The total mass of the test cone and sliding rod is 300 ± 2g.
△ Cone size: height 145 ± 1mm, cone base diameter 75 ± 1mm, cone angle 30 ± 1 °.
When the test cone is in contact with the base plane, the large deviation of the test cone shall not exceed 1.5mm.
△ Conical metal cylinder size: height 180mm ± 2mm, cone bottom diameter 150 ± 2mm.

Verification items and conditions:
△ Verification items:
1. Appearance inspection.
2. Check the total mass of the test cone and sliding rod.
Measure the dimensions of the test cone and conical metal cylinder.
Verification tools:
1. Balance: Weigh 1000g and have a sensitivity of 1g.
2 Vernier calipers: measuring range of 300mm, division value of 0.02mm.
3 universal angle rulers.
