Low-molecular-weight functional mother liquor with a maximum water-reducing rate of up to 40% and a certain slump-retention performance. Concrete workability can be maintained for up to 1.5 h. Concrete paste viscosity is relatively low, with relatively low dosage sensitivity and good adaptability. Suitable for high-rise pumping, manufactured sand with high stone powder content, high-grade concrete, and concrete with relatively high viscosity.
