Due to the increasing number and quantity of admixtures and the working performance of concrete varing greatly over time, the traditional working test method can not meet the requirements of modern engineering technology. Therefore, a kind of intelligent new concrete concrete rheological parameter measurement and control equipment is designed.This paper introduces the basic calculation formula of rheological parameters and the causes of errors in collected data in the measure and controller of concrete workability; When the rheological data is analyzed,the data is collected and lowpass filter processed and the Pauta, criterion is used to eliminate the error in LabVIEW.The results show that Combining two methods is effective to deal with the collected data and make the results of the rheological parameters test more accurate and reliable.
