Polycarboxylate polymer powder olycarboxylic acid powder breaks the convention in the production process and adopts thermal synthesis process, which can reduce production costs in terms of energy consumption. No release agent is added, and the purity of the produced products is higher, with the solid content controlled at around 98%. In terms of product performance, high-purity products have the characteristics of low dosage, high active ingredients and good collapse-preserving properties, further reducing customer costs.
Polycarboxylate ether superplasticizer has good dispersibility and flowability for cement at low dosage; When the dosage is greater than 0.12% to 0.22%, there is a very significant increase in the fluidity of the slurry; The loss of fluidity of the slurry within 1 hour decreases with the increase of the dosage.
The addition of water reducing agents can effectively reduce the amount of cement used in concrete, reduce the self weight of concrete, reduce the burden of construction, and reduce losses during the construction process.
excessive use of a retarder can result in slower setting speed of cement slurry, decreased concrete strength, increased concrete shrinkage, increased number of air bubbles in concrete, and decreased impermeability of concrete. Therefore, it is necessary to control the dosage of the retarder reasonably and avoid excessive use during the production process.
Concrete admixture is an important guarantee for the improvement of concrete performance. As an important admixture, water reducing agent can significantly improve the workability and physical and mechanical properties of concrete.
While maintaining the slump of the concrete, the water reducing agent can greatly reduce the water consumption for mixing and improve the quality of the concrete. However, due to multiple factors such as the decline in the quality of raw materials and the lack of professionalism of the staff, various phenomena will appear in the concrete mixture mixed with water reducing agent. The following will analyze and solve them one by one.
