Water reducing agent technical requirements

1. The water-reducing agent should be of stable quality. The water-reducing agent should have good compatibility with cement and admixtures. When multiple admixtures with different functions are used in combination, there should be good adaptability between the admixtures and between the admixtures and cement.
2. The technical requirements of high-efficiency water-reducing agents should comply with the provisions of Table 1. The technical requirements of polycarboxylic acid-based water-reducing agents should comply with the provisions of Table 2. The homogeneity of the water-reducing agent should comply with the current national standard "Concrete Admixtures" (GB8076) regulations.
Naphthalene series high-efficiency water reducing agent
Naphthalene-based superplasticizers can be divided into high-concentration products, medium-concentration products and low-concentration products according to the Na2SO4 content in their products. Most naphthalene-based superplasticizer synthesis plants have the ability to control the Na2SO4 content within Capacity below 3%, some advanced companies can even control it below 0.4%. The Na2SO4 content between 15% and 20% is a low-concentration type, and below 5% is a high-concentration type.
