Equipment Process of Online Testing Fresh Cement Concrete Rheology

摘要

Transforming the cement concrete mixer, simulating twin-shaft mixing process on large mixing plant, adding real-time acquisition equipment of torque and speed, and achieving the online monitoring of concrete mixing process. The influences of speed and stirring time on the liquidity of fresh cement concrete was deliberated, so that it were analyzed from three indicators of concrete slump, stirring torque and compressive strength to determine the optimum stirring speed 48r/min, reasonable mixing time 40s ～ 50s, and mixing time less than 100s.
