Mortar setting time measuring instrument using method

Use method of mortar setting time tester :

1. Put the evenly mixed mortar into the test mold, smooth it about 10mm from the upper plane, and place the test mold on the pressure disc. At this time, rotate the zero nut supplier Hebei Dahong Experimental Instrument Co., Ltd. Set the pressure gauge to zero.

2. Then manually press the pressure bar downwards by hand, and push the test needle into the mortar 25mm within 10s. At this time, the pressure gauge is shown as * measured value, and the adjustment nut is adjusted to the high position of Zui ( It is flush with the upper end of the test needle holder. The pressure rod is released and the test needle is reset under the action of the spring force. The supplier Hebei Dahong Experimental Instrument Co., Ltd. repeats every half hour. When the resistance value reaches 0.3MPa, it is changed to 15min. Once, until the resistance value reaches 0.7 MPa.

3. Calculate the penetration resistance of the mortar.

4. After the test, wipe the workbench panel, test needle and contact surface; remove the sample from the test mold, wipe it clean, and apply oil to prevent rust.

The mortar clotting time tester ends:

1. Wipe the workbench panel, test pin and contact piece clean. Work surface should not be stressed (less than 1Okg).

2. Take the test sample from the supplier Hebei Dahong Experimental Instrument Co., Ltd., scrub and clean the oil and rust, and use the release agent before use.

3. The sliding part should be lubricated frequently to make the instrument work normally.

4. It should be placed in a quiet and non-corrosive and non-medium environment at room temperature around 20 °C.
