Objective To improve the detection method of bulk densityof powder materials, in order to improve the accuracy and efficiency ofthe detection results of cement. Methods Through the improvement ofauxiliary metal rod rotation technology at the pipe to loosen thematerial and make it fall naturally, the detection data before and afterthe improvement of cement volume density detection technology werecompared to find a more environmentally friendly, faster and accuratetest method. Results The improved test data did not fluctuate due to theequipment displacement, and the cement bulk density remained at ${1.03}\mathrm{\;g}/{\mathrm{{cm}}}^{3}$ inthe loose state, the whole test process took a short time ( ${1.5}\mathrm{\;{min}}$ ), there was no dustin the test process, and the test results did not exceed the errorrange, all of which were better than the measured data before theimprovement. Conclusion The improved test method can improve theaccuracy and precision of cement performance test more scientifically,and can make the test results closer to the real value, which isfeasible, has certain social and economic value, and is worthpopularizing.
