Abstract：This paper tested the solid content of poly carboxylic acid water reducing agent(PCE) by weight method and sys-tematically studied the liquor types,sample quality,the baking time,temperature,composite material on the impact of test values. Results showed that,when test the solid content according to the existing national standard GB/T 8077—2012 "Methods for testing uniformity of concrete admixture",the measurement of solid content of PCE was prone to deviate from this theoretical value be-cause of using different testing methods. When the amount of sample near 4 g and the drying time between 4~6 h and the drying temperature to 105℃,the test value agreed well with the theoretical value of PCE.
