Background
The cement paste is a mixture with a certain plasticity prepared by mixing cement with water, namely pure cement paste and cement paste without sand and stone. An artificial stone formed by hydration and hardening of cement is called as cement stone or hardened cement paste, sometimes referred to as cement paste. The cement paste fluidity is an index for evaluating the quality of naphthalene-based admixtures (testing the change of the water-reducing rate of the admixtures), but for polycarboxylic acid admixtures, the paste fluidity method is not very accurate, and the best method is trial mixing. The standard should be with a cement with a special test admixture. Some people in reality test the compatibility of the admixture with the actual cement. The fluidity of the cement paste has no standard value, and the high fluidity indicates good workability. The net cement flow degree represents a measure of the hydrostatic cement flow, which, at a given water addition, depends on the water demand of the cement. The fluidity is expressed in terms of the mean diameter (MM) of the extension of the cement paste on the flow table. The testing process of the fluidity of the cement paste is to quickly inject the mixed paste into the truncated cone circular mould and lift the truncated cone circular mould in the vertical direction, start a stopwatch to time at the same time, let the cement paste flow on a glass plate (the glass plate should be adjusted to the horizontal state) to 30s, measure the maximum diameter of the flowing part in two mutually vertical directions by a ruler, take the average value as the fluidity of the cement paste, and particularly provide the fluidity tester of the cement paste.
