Polycarboxylate superplasticizer is one of the concrete admixtures often used in concrete. It can reduce water consumption and improve the strength of concrete under the condition of the same workability and cement dosage.
The role of polycarboxylate superplasticizer
Polycarboxylate superplasticizer can effectively reduce the loss of concrete slump and improve the fluidity of concrete. In the past, the water-reducing agents used in concrete were generally ordinary superplasticizer admixtures such as pulp, and the water-reducing rate was very low. Appeared, the best superplasticizer for concrete can effectively improve the efficiency of cement use, save a lot of cement consumption, and increase fluidity.
In addition, the superplasticizer can prolong the time for concrete to set and solidify, which is more convenient during construction, and is also conducive to the control of concrete temperature. After the cement mixed water is stirred, a hydration reaction will occur, and a little flocculated structure will appear, so it can better improve the workability of the unsolidified concrete, and can better meet the requirements of the construction in high temperature areas. need. The use of superplasticizer can also significantly reduce the internal void volume of the cement, and the concrete will be more compact, so that the compressive strength of the concrete will be greatly improved.
Polycarboxylate ether superplasticizer plays an important role in the construction process of concrete. It can better improve the performance of concrete without changing the water consumption, and it will not affect the construction conditions of concrete. The above content is the introduction of the function of polycarboxylate ether superplasticizer in use.
