UHPC Optimal Mixing Process Parameters - Qinglong UHPC Mixing Technical Specification

The UHPC mixing time is generally 3-5 minutes, depending on factors such as mixer type, rotation speed, and batch size. Forced-action mixers are recommended at 40-50rpm with a 3min mixing time; planetary mixers run at 20-30rpm for 4-5min. Through process testing, Qinglong UHPC has optimized and determined the optimal mixing parameters, ensuring uniformity ≥98% and even fiber dispersion.

Process control key points: dry mix for 1min first to blend the powders evenly; then add water and superplasticizer and wet mix for 2-4min; add fibers in batches to avoid clumping; check uniformity before discharge. One project adopted the parameters recommended by Qinglong UHPC, achieving good mixing uniformity, smooth construction, and strength that met standards. Scientific mixing ensures material performance.

Mixing Equipment Selection

Forced-action mixer: high efficiency and good uniformity; planetary mixer: suitable for small batches; adjustable speed: adapts to different mix proportions; capacity matching: suited to construction volume. Suitable equipment is the foundation.

Process Parameter Optimization

Dry mixing time: 1-2min; wet mixing time: 2-3min; fiber addition timing: after wet mixing; total time control: 3-5min. Parameter optimization guarantees quality.

Uniformity Assessment

Visual inspection: uniform color with no clumps; fiber distribution: no agglomeration; flowability: meets requirements; complete records: traceable. Quality inspection is indispensable.

Precautions

Ambient temperature: affects mixing time; material temperature: controlled within a certain range; batch size: matched to the equipment; cleaning and maintenance: keep the equipment in good condition. Details determine success or failure.

Scientific mixing realizes material value. Qinglong UHPC provides professional guidance to ensure mixing quality.
