1, Difference: Water reducer products can keep the working degree of cement paste, mortar and concrete unchanged and significantly reduce the mixing water consumption, which can significantly improve the concrete strength, improve the frost resistance and impermeability of concrete or reduce the cement consumption. Retarders delay the setting time of concrete and have no obvious influence on the later strength, and prolong the hydration and hardening time of cement, so that fresh concrete can maintain plasticity for a long time, thus adjusting the setting time of fresh concrete.

2. Let's say that * * * is the same: because both of them are admixtures that react with cement and water by mixing them into concrete materials, they realize a certain function in the process, and at the same time, sodium gluconate is a chemical product that can be used as raw materials in both products.
