Concrete admixture is added in the process of mixing concrete, which accounts for less than 5% of the cement mass, and can significantly improve the performance of concrete.
The characteristics of concrete admixtures are many varieties and small amount of admixture, which has a great impact on the performance of concrete. It has the characteristics of less investment, quick effect and significant technical and economic benefits. With the continuous progress of science and technology, admixtures have been used more and more, and admixtures have become the fifth important component of concrete in addition to the four basic components.
The admixture has a certain improvement effect on the anti-carbonization performance of concrete. There is a certain linear relationship between the carbonation depth and porosity of the concrete; the admixture has a great influence on the frost resistance of concrete, and the concrete with air-entraining water reducer The performance is better, but the early mixing agent alone does not improve the frost resistance of concrete.
Water reducer is a kind of concrete admixture which can reduce the water consumption of mixing under the condition that the slump of concrete is kept basically unchanged. Most of them belong to anionic surfactants, such as lignin sulfonate and naphthalene sulfonate formaldehyde polymer. After adding the concrete mixture, it has a dispersion effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement dosage and save cement.
For our company, we are manufacture of PCE liquid and powder .For PCE liquid, we have 40% and 50% solid content .We mainly supply DK-100,DK-200,DK-101,DK104 . Among them, DK-100 is the basic one for water reducing and DK-200 is for slump retention.
For PCE powder, we can recommend DKF-605 and DKF-606 which is our newly developed and enjoys good feedback at our mainland .
