Cement fluidity electric jumping table (also known as cement mortar fluidity tester) is used for the fluidity test of the new standard GB/T2419-2005 "Cement mortar fluidity determination method" issued in 2005. It is the only designated standard in this standard. with instruments.

Instructions:

1. Connect the plug to the corresponding hole of the counter, and connect the counter to the power supply. If the jumping table has not been used within 24 hours, first empty jump 25 times in a cycle.

2. Materials and quantities to be weighed in one test: cement 300 grams, standard sand: 750 grams, water: calculated according to the predetermined water-cement ratio. The making of mortar is carried out according to the relevant regulations of GB/G17671.

3. Put the mixed cement mortar into the mold quickly in two layers. The first layer is installed to about two-thirds of the height of the truncated cone. Use a knife to make 5 times in two directions perpendicular to each other, and then use a tamper. The stick is evenly tamped 15 times from edge to center. Then install the second layer of mortar, which is about 20mm higher than the truncated cone round mold. Similarly, use a knife to make 5 times in two directions perpendicular to each other, and then use a tamper to tamper evenly from the edge to the center 10 times. The first layer of tamping depth is tamped to one-half of the height of the mortar, and the second layer is tamped to no more than the surface of the tamped bottom layer. The tamping sequence of the tamping rod is in accordance with the provisions of Article 6.3 in GB/T2419-2005 "Determination of the fluidity of cement mortar".

4. After tamping, remove the mold sleeve, tilt the knife, and wipe off the mortar that is higher than the truncated cone round mold at approximately horizontal angles from the middle to the edge, and wipe off the mortar that falls on the table. Lift the truncated cone upright and gently remove it. Immediately press the "Start" button of the counter to complete a cycle of 25 beats.

5. After the beating is completed, use a vernier caliper with a range of 300mm to measure the expansion diameter of the bottom surface of the rubber sand in two directions perpendicular to each other, calculate the average value, take an integer, and express it in mm. The average value is the fluidity value of cement mortar.

6. The test should be completed within 6 minutes from the start of adding water to the mortar to the end of the diameter measurement.

Operating procedures:

1) Check whether the power supply is complete before use, and perform idling to check whether each control element works normally.

2) Prepare the sample according to the specification, wipe the table top, the inner wall of the test mold, the tamper, etc. with a damp cloth.

3) Put the mixed mortar sample into the test mold in two layers. The height of the first layer is 2/3. Use a knife to draw 5 times in each direction, and use a small knife to draw 10 times and evenly press 10 times. Scrape the test mold.

4) Gently lift the test mold vertically, start the jumping table, and complete 30 jumps within 30±1s.

5) After the beating is completed, use calipers to measure the diameter of the bottom surface of the mortar and the diameter in the vertical direction, and the average value is calculated as the fluidity of the cement mortar with this amount of water. The test must be completed within 5 minutes.

6) Regularly maintain and clean all instrument components every six months.
