摘要：

A simple gravimetric method is devised to determine the percent flyash in flyash blended cement. Insoluble residue of the sample was determined by the British Standard method. The flyash content was calculated by taking the insoluble residue in ordinary Portland cement and flyash to be 0.46% and 70.74%, respectively. The accuracy and precision are good and the standard deviation of the method is less than 1% for three determinations.
