Product details
Measurement steps for water consumption of cement standard viscosity and setting time tester, standard Vicat apparatus, and standard viscosity tester:
After the mixing is completed, immediately load the prepared cement slurry into the test mold placed on the glass substrate, use a small knife to compact it, gently vibrate it several times, and scrape off excess slurry; After smoothing, quickly move the test touch and bottom plate onto the Vicat apparatus, and center them under the test rod. Lower the test rod until it contacts the surface of the cement paste, and tighten the screws1s～2sAfterwards, suddenly relax and allow the test rod to sink vertically and freely into the cement slurry. Stop sinking the test rod or release the test rod30sRecord the distance between the test rod and the bottom plate, and immediately wipe it clean after lifting the test rod; The entire operation should be carried out after mixing1.5minCompleted internally. Sinking the test rod into the clean slurry and keeping it away from the bottom plate6mm±1mmThe cement paste is a standard consistency paste. The mixing water volume is the standard consistency water volume of the cement(P)Calculated as a percentage of cement quality.
Cement standard consistency and setting time testerDetermination of standard Vicat setting time:
1 Preparation before measurement: When adjusting the setting time tester's probe to contact the glass plate, align the pointer with the zero point.
2 Preparation of test piece: Prepare a standard consistency slurry with the required amount of water according to the standard consistency. Fill the test mold once, shake it several times, scrape it flat, and immediately Put it in a moisture curing box. Record the time when all cement is added to the water as the starting time for the setting time.
3 Determination of initial setting time: The specimen is cured in a moisture curing box until water is added30minPerform the first measurement at that time. When measuring, from wet Cement standard consistency and setting time testerRemove the test mold from the gas curing box and place it under the test needle, reducing the contact between the test needle and the surface of the cement paste. Tighten the screws1s～2sAfterwards, suddenly relax and let the test needle sink vertically and freely into the cement paste. Observe if the test needle stops sinking or releases the test needle30sThe reading of the hour pointer. When the test needle sinks to a distance from the bottom plate 4mm±1mmWhen the cement reaches its initial setting state; The time from the complete addition of cement to water to its initial setting state is the initial setting time of cement'min'express.
