Sensitivity of Polycarboxylate superplasticizer for dry mix mortar to dosage and water consumption
Because polycarboxylic acid superplasticizers are very sensitive to the change of raw materials, coupled with high water reduction rate, low cemelling material mix ratio, small water consumption and other factors, the performance of water reducing agent is very important to the water saturation of concrete. If the amount of concrete is excessive, there will be unfavorable phenomena such as concrete segregation, seepage, slurry running, hardening, and excessive air content. On the other hand, concrete will appear dry, poor workability, and large slump loss. And other issues. Therefore, in response to this issue, the following suggestions are made:
(1) The modified raw materials should be used for trial blending test to adjust the mixing amount to achieve the best effect;
(2) in the use of the process must strictly control the amount of Polycarboxylate superplasticizer for dry mix mortar and concrete water consumption;
(3) for raw materials in the concrete test of water reducer, try to adjust the water reducer to "slow" type, in order to achieve the purpose of insensitive to raw materials and water consumption.
