The cement mortar fluidity measuring method is a method for measuring the fluidity of cement mortar and testing the water requirement of cement. The mortar prepared from different cements has the same fluidity, and the water consumption required by the mixed mortar is different, so that the experiment shows that the water requirement of different cements is large and small.

The fluidity of the cement mortar is measured by a jump table method, and is expressed by the number of millimeters of the bottom diffusion diameter after the mortar is subjected to a jump test on the jump table according to the specification. The larger the jump table spreading diameter, the better the mortar fluidity. When the water amount required by the mortar to reach the specified fluidity is larger, the cement is considered to have larger water requirement; conversely, the water requirement is smaller.

The table jump method is carried out by putting a first layer of mortar in a test mold on a table jump in advance, then uniformly tamping the second layer of mortar for 15 times from the edge to the center of the test mold by using a tamping rod, then loading a second layer of mortar, tamping the second layer of mortar for 10 times from the edge to the center of the test mold, and tamping the first layer to half of the height of the mortar, wherein the tamping of the second layer is not more than that of the tamped bottom surface.
