Mortar consistency meter calibration method
●Appearance inspection technical requirements include visual inspection and manual inspection.
●Use a balance to weigh the total mass of the test cone and slide 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.
Mortar Consistency Meter Maintenance
●When storing or using the standard test cone, attention should be paid to strict protection and the outer cone surface and tip of the standard cone must not be damaged.
●After the test, the instrument should be cleaned and coated with anti-rust grease.
●Keep the instrument covered when not in use.
Technical requirements for mortar consistency meter
●The rack driving the dial should be clean and free of deformation.
●The position of the dial is fixed, and the scale lines should be clear and without deformation.
●The surface of the sliding rod and the test cone should be straight and smooth, and they should fall freely by their own weight without any tightness or looseness.
●The total mass of the test cone and slide rod.
●Test cone size height, cone bottom diameter, cone angle.
●When the test cone is in flat contact with the base, the maximum deviation of the test cone shall not exceed
●The height of the conical metal cylinder and the diameter of the cone bottom.

How to use the mortar consistency meter
●Put the mixed mortar into the container at one time, insert it with a tamper with a diameter of 10 times, tap the container several times, and place the container under the tip of the test cone. And align the center of the container with the tip of the test cone.
●Adjust the cone holder so that the tip of the standard cone is in contact with the surface of the mortar mixture and tighten the screws.
●Adjust the pin nut and the pointer to align with the zero position, and move the dial lifting frame to make the lower end of the rack lightly contact the upper end of the test cone slide rod.
●Loosen the test cone fixing screw and allow the standard test cone to sink freely into the mortar mixture. Tighten the fixing screw for a few seconds.
●Rotate the pin nut so that the lower end of the rack is just in contact with the test cone slide rod. Read the sinking distance from the dial in centimeters, which is the consistency of the mortar.
●Take the average of two tests.
Mortar Consistency Meter Operating Instructions
●Wipe the inside of the container, place it on the workbench, then turn on the power switch and the machine will start charging.
●The newly prepared mortar mixed according to the calculated mix ratio is poured into the slurry container until it is about centimeters away from the top of the cylinder, and the slurry container is vibrated to make the mortar surface level.
●Place the container on the tester so that the standard cone tip is in perfect contact with the slurry surface. Tighten the setting screw for better indication and mark the zero point.
●Press the start button to make the standard cone drop vertically and freely, and the time of sinking into the mortar is controlled to read out the sinking amount in seconds.
●After each test, the instrument usage must be recorded on the instrument and equipment status sheet.
Precautions for Mortar Consistency Meter
●Do not leave or chat with others during the test.
●Non-test personnel are not allowed to use this instrument.
●After each use, wash and dry.
Introduction to Mortar Consistency Meter
This instrument is widely used in testing and research units such as construction sites, highway bureaus, quality supervision bureaus, scientific research institutions, etc. Used to measure the fluidity of mortar. General fluidity, also known as consistency. The consistency of mortar is expressed by the number of centimeters that a standard cone of certain geometry and weight sinks freely into the mortar mixture under its own weight.
Mortar consistency meter parameters
●Sinking depth meters.
●Sink volume in centimeters.
●The minimum scale value is sinking depth in millimeters.
●Conical angle.
●Height mm.
●The diameter of the cone seat is meters.
●The combined weight of the cone and the slider is gram.
●Outline dimensions.
Structure of Mortar Consistency Meter
The instrument is mainly composed of chassis bracket, digital display scale, standard test cone, scale and material container.
The chassis and uprights are connected together using key spring washers and nuts. Two set screws on the cross arm respectively control it to slide up and down on the column and the scale to slide on it. Loosen the left set screw on the upright column and the cross arm can move up and down and then be fixed in the desired position. The digital scale can be zeroed at any position, and the vertical sinking depth of the standard test cone can be read directly on the scale.
