What is the water reduction rate of polycarboxylic acid water reducer

How much can the water reduction rate of polycarboxylic acid high-performance water reducer reach? First of all, we should know that the water reduction rate of polycarboxylic acid water reducer refers to the percentage of water consumption that can be reduced under the specified dosage, that is, the water reduction rate. For example, it was originally necessary to use 100g of water to make the mortar mix.

After adding the water reducing agent with the specified output, the mortar is stirred out with 82 grams of water. The conclusion is that the water reducing rate of the polycarboxylic acid water reducing agent under the specified output is 18%. This is mainly related to the solid content or parameters. The water reducing rate of the general high-efficiency water reducing agent can reach more than 40%, which has not been seen before.

It is also not applicable in actual production. One is the cost problem and the other is the construction problem. The of polycarboxylic acid is generally less than 45%, and naphthalene is generally only more than a dozen, less than 30%. Generally, polycarboxylic acid water reducer manufacturers will provide the water reduction rate of polycarboxylic acid water reducer.

However, the water reducing effect of polycarboxylic acid water reducer will be reduced if it is placed for a long time. Moreover, the water reduction rate of polycarboxylic acid water reducer is only the result obtained by the manufacturer under specific experiments, which has a great relationship with other materials in the concrete mixing process, so it can not be calculated by relying on a specific value.
