Highly effective water reducing agent

1. Scope of application:
1. Suitable for precast and cast-in-place concrete, reinforced concrete, and prestressed reinforced concrete in the construction of various industrial and civil buildings, water conservancy, transportation, ports, municipalities and other projects.
2. Suitable for formulating early-strength, high-strength, high-impermeability, self-compacting pumping concrete and self-flow grouting materials.
3. It can be widely used in natural curing and steam curing concrete projects and products. This product has a significant water reduction and enhancement effect, especially in the early stage. It can greatly speed up the turnover of formwork and site, and shorten the construction period. For steam cured concrete products, adding the recommended dosage of this product can lower the curing temperature and shorten the curing time. Steam curing can be canceled in the high temperature season in summer. Applying one ton of this product can save 40-60 tons of coal.
4. It has good applicability to Portland cement, ordinary Portland cement, slag Portland cement, fly ash Portland cement and volcanic ash Portland cement.
2. Main performance:
1. The appearance of this product is tan powder. The product is non-toxic, odorless, non-flammable and has no corrosion effect on steel bars.
2. To improve the strength, adding the recommended dosage of this product to concrete can reduce the mixing water by more than 18% when the cement dosage and slump are the same. Its one-day compressive strength can be increased by 60-110%, three-day compressive strength can be increased by 40-100%, and twenty-eight-day compressive strength can be increased by 25-45%. The strength in the later period is significantly improved, greatly improving and improving The various physical and mechanical properties of concrete improve the compressive, tensile, flexural strength, elastic modulus and long-term strength of concrete.
3. Improve the workability of concrete mixture and increase slump. Under the same cement dosage and water-cement ratio, adding the recommended dosage of this product can significantly increase the slump of concrete and improve the workability of concrete. The slump can increase by more than 12cm.
4. Save cement. When the slump and strength are basically the same, adding the recommended dosage of this product can save more than 10% of cement.
5. Due to the low chloride ion content of this product, it has no rusting effect on steel bars, thus improving the durability of concrete.
