Fluidity changes of sodium tripolyphosphate cement paste

Some experience about the application of retarding and plasticizing components is that sodium gluconate and other hydroxycarboxylates should be used in cement with more tricalcium silicate minerals, and polyphosphate, especially sodium hexametaphosphate and sodium tripolyphosphate, should be used. When adjusting the retarding and plasticizing components, we should pay attention to the mixing limit of each component, and consider the retarding property of each component after superimposition. We should not add excessive retarding components only to adjust the liquidity loss of the slurry. This kind of non-condensation accident caused by excessive use of retarding components in order to control the fluidity loss of the slurry is often seen.

After the initial fluidity comes out, we can adjust the retarding and plasticizing components to control the loss of the fluidity of the paste for one hour, and initially find out one or two better compositions. This step only needs to find out which compound scheme has the least loss of liquidity. At this stage, it does not require the greatest liquidity and no loss for an hour, but only consider which raw materials have obvious improvement effect.

When compounding, it is better not to use too many retarding components. Generally, the binary retarding components are enough. One of the excessive retarding components is difficult to control, and it also makes the production organization and management more difficult. The binary combination of hydroxycarboxylate and polyphosphate is enough to solve the general slump loss.

In addition to sodium gluconate, cement with more aluminate minerals must be compounded with some auxiliary components such as sodium tripolyphosphate. Additionally, adding monosaccharide has certain synergistic effect on sodum gluconate.
