Polycarboxylate ether water reducing agent is a commonly used concrete admixture used to adjust the fluidity and workability of concrete. The size of its dosage will have an impact on the performance of concrete.
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.
East Chemical participated in Shenyang's first large-scale charity-themed city walking event with the theme of "Jointly Participating in Charity and Creating a Better Life"
Slow-release monomers, functional monomers, reactive monomers.
redispersible latex powders have a wide range of applications.
Method and selection of using hydroxypropyl methyl cellulose (HPMC) in different application scenarios. For concrete putty powder, choose HPMC with a viscosity of 100000 and mix it directly with dry powder in a ratio of 3/1000. When using, add water directly because the cellulose has been completely mixed with the putty powder and there will be no agglomeration phenomenon. For the preparation of building adhesives, choose cold water soluble cellulose with a viscosity of 200000 and adjust the dosage as needed. HPMC gradually shows consistency after being placed in water, reaching its maximum consistency within approximately ten minutes. For spraying applications, choose cold water instant HPMC, with a shorter initial viscosity time as long as it does not clump.
Hydroxypropyl Methyl Cellulose) is a water-soluble polymer compound commonly used in construction materials, medicine, food, cosmetics and other fields. Here are some details about the use of HPMC
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.
