Detailed Introduction

YL-09NP-复配外加剂

YL - 09 np early strength high efficiency water reducing agent


Products overview:


           YL - 09 np early strength jianshuiji early strength and water reducing components such as composite and become a kind of free chlorine concrete admixture, good early strength and water reducing performance, under the condition of low temperature environment greatly improved concrete early and late strength, significantly increase the pumpability, improve the workability, as the main measures of speeding up construction schedule and improve working efficiency has been widely applied in all kinds of engineering.

The main technical performance:


         1, the dosage of 1.5 2.5% of gelled material, can reduce the unit water consumption is 10-15%.
         2, added to the product under the condition of the same slump, 10-15%, and can save cement strength is not reduced.
         3, suitable for steam curing, the rapid growth of the strength in the same water and slump conditions, concrete strength by 50-120% a day, three days strength increase 40-100%, 7 days strength increased 30-80%.
         4, late added to the product of the concrete strength increases correspondingly.
         5, 5 ℃ to 30 ℃, the suitable conditions of concrete engineering, can speed up the template turnover increase progress, economic and technical results are good.
        6, the product not retarded air-entraining, has extensive adaptability to cement, can improve the main mechanical properties of concrete in an all-round way, improve permeability in concrete, had no effect on drying shrinkage of concrete.
