GQ-201 superplasticizer is the result of a non-air entraining a series of chemical reactions synthesis of superplasticizer, the main ingredient is naphthalene sulfonate formaldehyde condensates, water reduction, enhancement remarkable adaptability of cement well, we can fully enhance and improve the performance of concrete, widely used in roads, bridges, tunnels, dams, docks, power, water conservancy, civil construction and steam curing and prefabricated nature conservation. Homogeneity ◎ Specifications: ◆ Appearance: brown or brown peg color toner was liquid. ◆ powder Solid content ≥92%, liquid solid content 40 ± 0.2%. ◆ powder fineness: 0.315mm sieve ≤10%. . ◆ paste fluidity ≥230mm ◆ PH value: 7-9. ◎ The main technical performance: ◆ powder dosage is 0.5-1.5% gelling material, the liquid content of 1.5% -3% water reduction rate of 15-25%. ◆ early strength and enhance the effect is remarkable, strength can be increased 20-60% ◆ water-cement ratio in the same situation, can increase the slump more than 10cm. ◆ that same strength of concrete at the base of the case, can save 10-20% of cement. ◆ concrete superplasticizer incorporation GQ-201, the workability and working remarkably improved. ◆ after the incorporation of the agent, can improve the compressive, tensile and flexural strength and late strength of concrete. ◆ Can be used with other components of complex, various types of additives formulated to meet the different requirements of engineering applications.
